Can you drill holes in carbon fiber?

Can you drill a hole in carbon fiber handlebars?

Never, ever drill or damage the structure of carbon fibers in any way. It’s akin to cutting a woven rope with a knife, you’ll weaken it’s strength tremendously and that’s definetely not what you want in such a stress loaded device as a handlebar even if it seems overbuild.

Yes, there is a slight weight gain, but we’re talking less than the difference between an aluminium and titanium bottle cage bolt.

How do I know if my carbon fork is damaged?

Carbon rods will never tap well. The structure is like wood, with fibers running along the length. The material will tend to shatter and crumble rather than cut like metal.

Is it safe to cut carbon fiber?

How do you cut carbon tube?

When cutting composites, it is ideal to use a diamond coated abrasive cut-off blade rather than a toothed blade. Teeth can catch the fibers and tear the material resulting in splintering or delamination. Thicker tubes may generate enough heat to re-activate the epoxy causing the blade to “gum-up”.
