Cutting a drilling CF?
« on: August 15, 2022, 09:55:16 AM »
What’s the best way of cutting and drilling CF without damage?

I have some CF gear I need to trim a little and drill some holes for axles and mounting bolts.
Thanks

A high speed steel 1/8” drill will go through 2” of carbon composite before it’s defunct. A carbide bit is better. Spin the bit fast. You can use isopropyl alcohol as lube. Diamond scroll saw blade from Amazon works great for cutting composite. Sandpaper works too.

Thanks Howard.
I need to trim some off. Can I use a Dremel tool with a cut off wheel?

Dremel tool cut off disk works great on composite stuff. Belt sander is nice too. Cut and sand lightly or you'll fuzz the end. I try not to use saw blades, they go south quick. I use one of those respirators with the rubber face cup from home depot. It's the only thing I've found that doesn't leak. Once that CF is inside your body, it don't leave. That stuff floats in the air for a long time so, do your job then leave the area for a while.
