Colt 10150700 FCE Professional HSS Pen Blank Drill Bit, 7mm

Pen making demands exceptional speed, accuracy, and long service life and Colt's 5 Star bits deliver in spades. These brad point bits will zip through all types of materials, even plastic, faster, more accurately, and with less heat, than any other bit. The 5 Star cutting tips are optimized for end grain drilling to bore extremely fast and make exceptionally clean entry and exit holes. Large parabolic flutes remove chips and debris without burning or jamming. All these features make the bits capable of end grain drilling the full length of a blank in a single pass - a real time saver! Not inexpensive, but well worth the price in terms of speed, accuracy, service life, and headaches saved. Made from tough, long-lasting M2 HSS. Bits are approximately 6" long. The shanks of bits 27/64" and 11mm or larger are reduced to 25/64". Germany
