Drilling Carbon Fiber Chassis
I would like to have some experienced chassis builders let me know on drilling holes and countersinking into a Carbon Fiber Chassis.
I have never quite been able to get a smooth hole or countersink. When drilling through on my drill press even with a block of wood under the chassis to drill through and into the hole is not smooth edges like at the factory where a chassis is made.
Basically the holes on the exit side may get a little splintered. Do they use like a grinding stone drill bit or faster speeds or certain feed rate?
On countersinks I find the end finish is not as nice as the factory did. I use the 90 degree for metric and a sharp mult-flute countersink. Is this a special grinding countersink tool?
