I make hundreds of pens every year and cannot believe the performance of the COLT Pen Bits. The fastest drilling, chip removal, no heat build up (which cracks most exotic woods), no bottom blowouts, and a perfect hole every time.

These precision drill bits are made from M2 High Speed Steel for longer life. They can drill up to 1,000 holes without sharpening depending on the density of the wood. The patented self-cutting drill point design guides the bit straight in end grain and guarantees a clean entrance and exit hole.
These precision Colt drill bits are made from M2 High Speed Steel for longer life. The patented self-cutting drill point design guides the bit straight in end grain and guarantees a clean entrance and exit hole. The deep parabolic flute shape clears the chips without repeatedly having to back the bit out during the cut. Friction is also reduced by the concave shape of the outer flute area, making for faster drilling and less heat build up. We offer these bits in 7mm, 8mm (letter O size), 10mm and 3/8".
The 7mm bit measures 109mm (4.29") overall length.
The 8mm bit measures 117mm (4.61") overall length.
The 10mm bit measures 133mm (5.25") overall length.
The 3/8" bit measures 125mm (4.92") overall length.
