DOTCO 14-2421 Router Bits with 1/4" Shanks Accessories are designed for use on Dotco 12-10, 12-20, 12-25 and 12-40 series and comes in 4 dimensions, A: 1", B: 3/8", C: 1/4" and D: 1/8". The minimum router bit length (OAL) to be used is determined by the formula: OAL = 1-13/16''+C+P (series 12-10); OAL = 2''+C+P (series 12-20 & 12-25). "C" is the "C" dimension of the router guide and "P" is the desired protrusion of the router bit. DOTCO 14-2421 Router Bit with 1/4" Shanks Accessories are made of high quality material and engineered to outlast and outperform the competition in the harshest environments. With years of experience, Dotco's engineering and manufacturing techniques produce pneumatic tools that are small, comfortable, lightweight, and can withstand the most rugged environments. Crafted with meticulous attention to detail, the Dotco tool is engineered for compatibility with 1/4" Shank Bits, offering versatility in routing operations. The 1/4" Shank capacity of the Dotco 14-2421 Router Guide makes it suitable for a diverse range of routing tasks, allowing users to work with different materials and achieve desired outcomes.

Important: Insert bit into the collet as far as possible, then pull out 1/16" and tighten the collet.

In an emergency: If it is necessary to pull out the bit more than 1/4", be sure to insert a short length of blank shank (not to exceed 5/8” long) in the bottom of the collet before inserting the bit.
