Tips film #41 - Analyze tool wear in solid carbide drilling

- The goal in solid carbide drilling is to obtain a balanced wear across the drill’s cutting edge. Uneven tool wear indicates a problem in the drilling process that can result in shorter tool life, tool breakage and damaged components. In this film, we demonstrate how to identify tool wear problems and workpiece errors when using solid carbide drills. For more information visit www.sandvik.coromant.com/solidroundtools

I respect how still you stand while speaking... like a damn chuck head...only your mouth moved.
Priceless. Ty.

Good stuff.

What I'm missing is information about spot drilling in combination with solid carbide drills (when to use or not and choice of angles).
I called my sandvik rep and got this: Anything over 8Xd definitely need pilot. 5xd you may want to spot with something with a spot drill with an angle equal to or greater than the drill being used. Also, when drilling radially a small spot may prevent drill walking. When you start drilling deeeeeeeep holes 12XD -18XD and up you should always call and make a plan of attack with your local tool rep.
Hi,
Thank you for this input. We will add this to the list of subjects for future tips films.

Hello Sandvik, I heard that the surface finish of the chip also says a lot. Shiny means a good cutting speed, dull is too slow. Do you agree?
Yes you can say the surface finish of the chip indicates you have the correct data for a successful operation but the shape of the chip is the most important factor when determining excellent chip control. Other factors can contribute to a shiny finish of the chip such as material hardness, coolant type and concentration with a dull chip showing not enough heat in the process so the solution would be to increase the speed.
