Features and benefits

DAL drills for machining of CFRP-metal stack materials.
Material-specific SC drill for combinations: CFRP-Ti-Al as well as CFRP-Ti, CFRP-Al, and also straight Ti or Al; with double-angle point design for bur-free exits when exiting metal side of stack.
Sharp cutting edge to cleanly cut CFRPs as top layer in CFRP-metal stacks.
The drill diameter is ground to a k6 tolerance and can achieve hole tolerances of H8.
Excellent centering capabilities.
