NACHI Diamond Drill Bit Crystal Coat DCDCF0550 1pc

Drill for cutting holes in CFRP
-Drill suited to cutting holes in CFRP, which is a difficult-to-machine material
-Reduces CFRP delamination and exit burring for high-quality drilling
-Small cutting resistance and excellent wear resistance help increase tool life

Suitable for cutting holes in CFRP
CFRP is a composite formed by curing carbon fiber impregnated with resin.

It is highly resistant to wear, heat, and oxidation, and also boasts excellent thermal elasticity. It has strength and stiffness comparable to iron, steel, and other metals, yet is far lighter, a characteristic that makes it a popular choice of material for building aircraft.

CFRP, however, has the following drawbacks:
-High hardness of carbon fiber
-Easily delaminates due to low resin strength
-Low cutting-heat resistance of resin at 200?

Crystal diamond coated drills feature a unique cutting edge design that delivers excellent cutting performance and diamond coating with enhanced crystallinity. The reduced cutting resistance and increased resistance to wear will ensure a longer tool life for use with difficult-to-machine materials.
