Pocket Cutter Bits - for Automatic Knife Coil Springs

Create clean, accurate coil spring cavities for spring-assisted folding knives with these Heavy Duty Coil Spring Pocket Cutter Bits. Designed specifically for precision knife makers, these high-performance annular cutting tools provide fast, accurate, and virtually burr-free holes in steel materials, making them an essential tool for creating reliable spring pockets and other precision applications.

 

Unlike traditional twist drills that cut through the center of the hole or hole saws that can tear and leave rough edges, annular coil cutters remove material around the outside edge of the hole while ejecting the center as a solid slug. This hollow cutting design eliminates the dead zone found in standard drills, resulting in smoother cuts, reduced cutting resistance, and improved hole quality.

 

Manufactured from high-speed steel for durability and long service life, these pocket cutter bits are engineered for use with steel materials and deliver consistent performance when properly lubricated. They are designed to work with the B11122 guide system and provide the precision required for custom folding knife construction.

 

Available in multiple diameters to accommodate different spring cavity requirements, these Heavy Duty Coil Spring Pocket Cutter Bits are ideal for professional knife makers and hobbyists building spring-assisted folders.

 

Note: Pocket cutter head versions are only compatible with the B11122 guide. Proper cutting speed and lubrication are recommended for best performance and tool life.
