Using a magnetic drill for drilling steel is the easiest quickest and most economical way to make lots of different size holes in steel beams and thick steel.
I have owned the rotabroach Panther for many years and i have to say that it is one of my favourite machines that I have in my tool kit!!
7:29 Robin, dont forget to use those safety glasses on your head to protect your eyes from flying swarf. That stuff will take your eyes out.
3:09 nice swimming pool you've built Robin. ;)
Another excellent video. Having the right tools always makes the job easy!
Great bit of kit!
Great job, Robin
Use straps not only for drilling upside down, but for drilling into a side as well if possible.
A very civilised way of drilling steel on site👊 Cheers Robin
Cheers Del!!
That's fast, I wasn't expecting that.
You forgot to wear your eye protection after telling us of the dangers of the shavings around 7min 30 secs.
OK, fair enough, but easily done when explaining thing to others. Let's not be too harsh out there!
Brilliant Robin seen a lot of these drills on site but never knew how quick and efficient they clearly are .... Noting the safety issues that you rightly highlighted from previous experience which is something that always concerned me as it is a heavy bit of kit. But fantastic to see it in use by and expert 👍
Great Drill for drilling beams 👍🇮🇪☘️🤟
i have used these magnetic drills over and over again in many occasions while i was a contractor,i rented them for the day as i needed them,but these things are golden mate,they do a brilliant job :-),you can't do it more easy then this,keep it up you are a craftsman Robin Clevett
Looks like it would be good for safe cracking!
i spent a summer when i was fifteen drilling two inch holes for my dad in the city , hundreds of holes every day for the six weeks of my holiday !!!
Great video !! thanks
Cheers Robin 🍻👍
Hi Robin, was watching old vid of you with Roger and ply rafter template you set up for skil saw with 30 rafters, Roger said to you, " aw I see, there's no flies on you"..when I said that to my mother, she was 70's at the time, she said " no, only dead ones"😉
My mother used to threaten to throw people out of the window no matter how big they were when she was annoyed. She was 5 foot!
I like the in door pool
You can also get twist drills that fit in a rotabroach chuck
Beautiful tool.
Learning tips and tricks with magnetic drill. I am interested in the gloves when working with steel beams.
My prayers with you and your family. Allah give you healthy long life with full of peace and happiness. Aameen.
Best wishes from Leicester ENGLAND.
What a great piece of kit that is just need to find a couple of volts 😄 to hack into
I've got a JEI minibeast. You can just about get it in between 2 joists. Plumbers and electricians are spoiled on my jobs. Got me out the shit a few times also like the job I'm on now where the position of a connection got messed up. Highly recommend
Have fastened wood to steel using bolts & predrilled holes or ramset gun but for quite awhile have been using wafer head self drilling/tapping screws for up to 16mm steel plate.
Be good to know what brand wafer head you use. Thanks in advance.
No eye protection on the second hole 😂👌
When not using the machine coolant bottle, (if horizontal or countersink bit) I use a Oasis bottle with a 1mm hole in the lid and much cheaper soluble oil diluted with water. You can squirt a very fine flow on your bit as much as needed. I have a small cheap mag drill and a big boy Rotabroach Element 100.
Sub floor is bang on level
Interesting tool. Manufacturer not available in US, but others are offered at prices $220 😒, $800, $1,000. Seems reasonable for a portable drill press. Even if it is manual feed. Thanks for the video.
I'm glad you mentioned that safety bit about drilling upside down at the end of the film. Nothing makes one more nervous than standing on a tiny stepladder with one of those beasts above you.
My steel supplier let me borrow a Mag. drill and I was doing exactly as you describe first time ever use, stepladder etc. Unbeknown to me my ever helpful wife was behind me, camera in hand, just as I switched the drill on she took a pic. The camera 📸 flash scared the life out of me, l couldn't believe that I wasn't electrocuted 😱🤣..... One one of our many laughs on our major renovation project... Loving your professionalism on everything Rob. 👍👍
30 years lol how time flies
you should not wear gloves when operating such drill, if the glove will get caught you may lose some fingers etc.
just saying...
love your videos mate
HSE’s guidance states that gloves should not normally be worn by operators of pillar drills, undertaking this type of drilling work, due to the risk of becoming entangled with moving parts
Doing some ‘home improvements’ I need to drill some holes to the underside of a beam so I clamped a drill stand to the underside of a beam with an electric hand drill attached it did the job effortlessly, wasn’t worth buying a Mag drill
….then we should (always) put our eye protection on before starting to drill…so sharp those bits of swarf….
Centre punching your pencil marks makes centring the cutter so much easier, you can literally do it with you eyes closed.
Nice tip that!
Came to say the same. Spring that centre pin right into it for pin point accuracy.👍
Been using my rotabroach for years . The magnet is so strong ,I use mine to drill 12mm holes to accommodate a 10 mm rod to suspend a plate for a sliding partition: the power is unreal. I took my guard off (bad practice) and I use wd40 as a lube for the cutter to cut through the beam . Beware though… take your time when drilling as I’ve had a few cutters shatter over time.
I will never need to use a tool like that. Still, definitely want one.
Love the l”” it’s important to use PPE .. then leave the glasses ontop of ur head lol hey at least u had them
I use a Milwaukee cordless mag drill, it’s got a permanent magnet so no worries about power cuts, but still use the strap when upside down.
I am yet to try one mate are they good???
@@ukconstruction excellent bit of kit. They have quick release collar for the cutters too. Saves faffing around with Allen keys. Not having trailing leads is a godsend on a busy site especially when you are up high in a basket
@@markevans9130 Nice one Mark, I will get one!!
Agree with that Mark, great tool, good solid magnet, easy to use and surprisingly light in weight. 👍
they used to be called broaching drills back when you had to plug things in !
im suprised how littel lubricant you use robin. i use way more with mine. if i dont i find the cutters get very hot and dull quickly.
i use a waterbased oil for metal bandsaws that recirculate the oil. its white . a few letres is 35 euro or so and a cap or 2 of oil will create a litre of coolant. works out way cheaper than those spray bottles.
a mag drill is an amzing luxury to have. i couldnt live without mine and i dont use it that much but when i do it saves so much hardship
milling cutters and gloves is not a combination that always works well... as a toolmaker in the distant past i can speak with experience
A coworker had finished drilling a hole and hit the switch to disengage the magnet but accidentally started the drill again while he was holding the bit, his glove got caught up in the rotating bit and pulled his thumb off.
@@youtubecensorseverythingIsay yep I reached in to change a tool on a cnc . Was lucky it just pulled my glove off could have been much worse. Tools like to grab stuff
We were never allowed to wear rings or any other jewellery in the workshop as it could get caught on the ‘birds nest’ of swarf that spins.
Glad to see it is a Rotabroach. They claim to be the original and was all I ever used in UK. British firm I believe. Not very common in Oz. Holemaker seems to be the brand here. Great tools and so useful. A basic but reasonable one here is $1000 so bit of a luxury unfortunately.
Some of my friends don't believe I watch videos of blokes drilling holes in metal...
does the tin lid not cover that part filled with water ??
ideally eye protection needs to be worn in front of your eyes and not on your head!!!
I must be 2nd - You forgot your safety glasses on one of the holes - I would have edited that out. Love your channel.
It's like a plug cutter
“As loose as a goose” 😂
Hi Robin just a quick one. Your ear defenders are they comfy to wear and don't pressure your head? I've got a set of husquvanas but find I get a headache as they sit quite tight! Thanks
3:38 The Hole Idea :-)
Nice bit of 'Summer' weather you've been having Robin I see 😞
Hi. Who supplies your steel. I'm just nosy cos I'm in the steel trade.
How wide is it? Can they drill into the web of a beam?
These r weapons need to get 1
Hi Robin, So can I fire a nail through a 47mm wall plate first plus a bed or mortar and then into the steel with one of them guns...???
Certainly not sir! Not the done thing.
That goose. Was it in a clubhouse…….😂
Only you know our lingo bro!!!
I agree on using them for certain loads and for bolting steels to steels but if it’s just for a wall plate then a paslode spit gun or the older Hilti would be more than man enough. They are much more efficient you’d have your wall plates set and a few pairs of rafters cut and up into position by the time you’ve drilled those holes.
swarf Mr Clevett lol
1st
Hi Robin
Hi Robin did you know that cembrea make a set of cutters for a hand held drill.
Since when has a cordless drill and fresh drill bit not done the job?
Hi Mate i have seen some but not sure who made them!!
@@ukconstruction To be fair all the major tool brands have HSS bits capable of drilling a 10mm hole in seconds.
Lots of mag drills now come with a lube bottle to drip feed while cutting. Nice Wera ratchet screwdriver. 6:18
So does this one and I mention it in the footage!!
I'll pay more attention next vid. Sorry.
You can’t beat a tool in your arsenal 😂
If I heard correctly Robin you drilled a 14mm hole for a 12m bolt. If that for expansion or some other reason?
Its the perfect size enabling the bolt to fit without damaging threads etc
The technical term is clearance drill. Tables are available on the Web for the various metric thread sizes. 14mm is a bit sloppy for engineering fits, but I'm sure it gives Robin a little wiggle room in timber.
If you drilled the holes 12mm - when it came to bolting up you would only get one bolt through - out of however holes you drilled.
If the power cuts and stops the magnet 🧲 is there not a risk that the whole unit will start spinning? Or is there not enough torque left in the winding down drill bit?
It'll spin and probably snap the broach off if the hole is deep enough, if not it'll just wind down
@@youtubecensorseverythingIsay so when it spins would that not be dangerous to the operator? Arm breaker etc? Or not powerful enough?
@@mr-mojo-risin1248 they wind down pretty quick, I haven't heard of any broken limbs but if it's being used on its side or upside down it's necessary to use a safety strap or clamp it to the beam.
@@youtubecensorseverythingIsay yeah I just wondered about the torque once the magnet stopped. Didn’t know if it had a clutch or whatever, could catch you by surprise y’know. I’m not a driller so I’m speaking from a point of ignorance! Thanks 👍
Always use a safety strap using one upside-down incase the power fails.
Did you not hear me say that on the footage?
@@ukconstruction
I must have missed that
Apologies
I Blame the Mrs for distracting me
@@the1beard Theres no way the Mrs was distracting you when Robin is on the screen. When i watch these vids my wife practically drools over me shoulder.
@@m4inline
😂👍
Gloves shouldnt be worn with rotating machinery, lathes, drills etc, due to the chance of entrapment. (Ok with off hand grinders due to the disc guard position).
Hello boys
The magnetic one I've used is X10 times slower than that 😂😂
Not teaching you to suck eggs but I always centre punch before drilling keeps the spring loaded guide in place as they can wobble and jump off as the bit wears
Only a true pro carries on unaffected after being half-strangled by glasses cord (@8:10) 🤓 That safety gear can be dangerous!
Your not kidding. I once poked myself in the eye with the arm of my safety glasses as I was putting them on. Who’d have thought you need two pairs!
Pump that water out
My Mrs thinks this bloke's better looking than George Clooney.
I hesitate to offer advice to a master craftsman, but you are used to wood, I work with steel. NEVER ever wear gloves when you are producing long swarf - particularly cut proof gloves. The torque in that machine will absolutely be enough to pull the glove in and absolutely will NOT stop just because there is a hand inside - I don't care how strong the victim is - they will lose! I know this from experience and still have nightmares occasionally 30 years later - I had to help cut the poor sod free.
I appreciate your experience and that makes perfect sense, but if I filmed that without gloves then I would be criticised!! many thanks for your helpful and accurate comment mate
Robin, personally speaking, I would lift the tool out much more frequently to break the chips and to get more lubricant/coolant at the cutting edge.
U marry all different types of materials. That one steel beam has more load bearing capacity than all the bricks and mortar in the whole house. U bolt a 2x6 to that beam. It’s like a piece of paper and a chunk of steel. It just seems like overkill, the size and strength of that I beam. Enjoy all the tools. I’m like a kid in the candy store. I absolutely look forward to every video. They must miss u at Skill Builder. RC is quite the draw
Bill its nothing to do with adding strength, just gives Robin something to shoot nails into for the next phase of timberwork built onto it.
Why not get the steel fabricator to put holes in 🙄
I mentioned in the video that we sometimes have the holes done before the steels arrive on site, however due to lead times etc and also final positioning etc we sometimes prefer to do this ourselves
Take off the shirt bro. I hope I have your shape at your age!
