Thanks Roger, what a great tip. I’d thought the cheap ones from eBay virtually disposal, but this means I can use them again and again - brilliant. Regards, Gerry
wow, thanks. I was thinking it was the cheap saws I bought, or that I had been using them improperly when one of them started feeling really dull on the 3rd use. But if it's true that some people are using them 3-4 times and throwing them away then I don't feel too incompetent myself. I didn't have soft bricks but I do have a bunch of old, broken roof tiles and that seems to have worked alright.
I remember the original diamond hole cutters it was a specialist job them days with 2 rods secured in the concrete n a huge slow revving drill secured on the rods with a water pipe on the hole cutter 6 inches 8 inches no problem n the hole was just perfect It cost me £120 for a 110 mm non diamond tipped cutter how things have changed n the Hitachi Hummer drill was over £500
If you cut a peace of sponge the size of the cutter en put it the cutter and then dip it in water it wil release the water as you are drilling the hole so you don’t need to stop as often and there is a constant flow of cooling water around the cutting-edge
Can this cut through stucco typically found on outside of homes? I need to cut a 1 inch diameter and about 1.5 inch deep hole on the side of my garage to install a surveillance camera
Would you know if you can get a special tool like a hole saw so I drill around the nails in architrave so I don't have to pry the architrave off the wall and damage the plaster.
To use the holesaw without the pilot just make a hole in a piece of MDF or similar. Then remove the pilot drill and use the pre drilled hole as a guide over the nail.
Low speed for core drilling but be very careful if you have a drill with a lot of torque because at the very least you'll sprain your wrists if the core jams, and it's painful, believe me.
Teh problem with core drills of that size is that they are segmented so they can chip the tiles. If you start gently you will be fine. I use the Forgemaster range but any diamond core drill should do it.
Rather than constantly stripping off the coating and wearing out your bit you should just be using water or a proper lubricant/coolant while drilling with it. You won't need to do this trick he shows and your bits will last much longer.
Cannot understand how these are so cheap and still work. I guessed that it was carbide and silver paint..but even that brick would have stripped coating if so. The glazing is lack of water, or mineral oil, plus running too fast with too much pressure. Well now I'm going to get one and try it on glass.
Fitted 10mm porcelain tile couldn't stop them chipping out for love no money to tile saws 2 different new blades but the tile was just crap holesaw go through fine but to brittle to cut.
The hardest “Stone” for grinding is a “Diamond,” my “Birthstone”. “And he beheld them, and said, What is this then that is written, The stone which the builders rejected, the same is become the head of the corner? Whosoever shall fall upon that stone shall be broken; but on whomsoever it shall fall, it will grind him to powder.” Luke 20:17-18 KJV
Do us all a favor next time. Wear eye protection. And don't hold the bit in your left hand and your drill's trigger in your right at the SAME time. Don't prove Darwin correct.
Nice tip 👌🏼, I do that on my grinder blades .
Always put minimal pressure and let the blade do the work or it will overheat and glaze over 🧱👍🏽
Thanks Roger
Thanks again Roger. Awesome to know.👍
I look forward to these little TIPS keep them coming thanks
Great tip Roger
Thank you for this video. Be blessed.
Thank you Roger! :)
Top tip, Thanks Roger
I do landscaping and we always have a block of sandstone for the diamond blades 👍🏻👍🏻👍🏻
Thank you very much for your tip. Godbless you.
Roger your brilliant 👌
appreciate it, thank you!!
Great advice thanks man
Great tip

thx
wow it works subscribing
This is great❤❤
Wow your vids make me look pro bro 😎 love it!!
I ❤️ this guy!! 😁👌
Alway brilliant advice from Roger. Try Drill corebit into a piece of sponge. Then dip in to water it will keep core bit cool.
Great video batman.
I like the makita drill.

After few seconds tile will smashes the sponge while rotating, there is practical problems
Top Tip is that!
Good tip Roger. Something I hadn’t thought about doing! Just shows even the cheap eBay sets can be used more than once.
Diamond, geezer :)
I had two old porcelain basins I wanted to drill holes in to make sinks. This video helped me to cut the holes just perfect. Thank you so much!
Keep it clean for the win- 💯
What do you think of these compact circular saws? My AEG ripsaw is so heavy and I rarely use its maximum depth.
This video is a diamond in the rough
Buy in Lidl. They are cheap but works. I only spit little water on and dril...
Great guy
Its like dressing a blade
Just the dressing blocks are very expensive
can I use a diamond bit to make holes into a abs board?
Can this cut through stucco typically found on outside of homes? I need to cut a 1 inch diameter and about 1.5 inch deep hole on the side of my garage to install a surveillance camera
Excuse me sir, can I use these diamond gears to hollow out the gemstones
Drill guide holds hole saw in place during cutting!
Just put the wet sponge on the wall above it and let it trickle down over the bit as you go, one sponge wetting per hole.
The heat is also a big killer, I dip the hole saw in water a few time as I go.
I used to do that but I found that getting it hot and then cooling it quickly cracked the braze. Better to keep it cool all the time.

Would you use the drill on the high or low setting for this application please.

Nice one, Roger. How do you start the hole off without the hole saw slipping?
Start in an angle, so just one small section of the blade do touch, he does show it quickly when he his outside and start drilling in the brick.
@@AustraliaClaude Thanks! Yes, I see what you mean.
havent you shown us this before, got some DejaVu happening here!
It was in the bathroom videos but we thought it might get more views as a stand alone.
Great tutorial Roger, thanks. Any chance you do a video on cutting slabs with an axilgrinder and best disks to use? Thanks.
Angle grinder? Use a diamond blade..
You done this before
Thanks for the tip! Do you go all the way through the wall with this same bit, or do you switch to a different one to save the diamond bit?
I usually change bits once I am through the tile.
I thought I saw this posted some time ago already?
Hi Roger
Can you recommend a good 4 inch core bit to drill through tiles and into masonary.
I want to install an extractor fan in my bathroom.
Teh problem with core drills of that size is that they are segmented so they can chip the tiles. If you start gently you will be fine.
I use the Forgemaster range but any diamond core drill should do it.
Good call Roger. Every day is a school day
how do you stop them from slipping on smooth tiles
Make up a guide by cutting through a piece of plastic then hold it on the wall.
Put the wet sponge inside the bit.. dip into water periodically
Too much water is not recommended by some drill bit reps roger?
Have a look at our Hilti video on diamond cutting. They flood it.
Rather than constantly stripping off the coating and wearing out your bit you should just be using water or a proper lubricant/coolant while drilling with it. You won't need to do this trick he shows and your bits will last much longer.
Can you use this to cut through a concrete patio block?
It might do one slab but generally you would need a heavy duty core for concrete. What size hole?
@@SkillBuilder 1 inch in diameter, 1.75 inches deep

Dude! Eye protection, please- we need you.
I swear I've seen this in another video you've posted.
He did he done it with a hole saw set with an SDS, i'm sure he said run it through sand though.
@@reubenklang3968 No not sand but maybe sandstone. Anything that is gritty.
Where are your ear defenders/plugs? Its noisy work using a core bit.
Pardon!

Yeah, we all have old bricks lying around the house 🤨
Old video reposted 🤔
But wetting the diamond bit would not make it rusty.
The rust goes within seconds
