Variable position chamfer tool. Drill and deburr or chamfer
in one operation!

• Converts any standard twist drill to a step drill or chamfering tool for counter-sinking or deburring.
• Stocked for all standard drill sizes from 1/8' to 1" or 3mm to 25.5mm.
• Economical alternative to custom multi-diameter drills.
• Unlike a multi-diameter drill, the Cham-Bit can be disassembled from the drill and easily
resharpened over and over.
• Rugged cutter and collar interlock to the drill with a combination of three set-screws forming
a positive stop of great strength.
• Optional Stop-Bit back-up spacers can provide an alternative positive stop backed all the way
up your tool holder for precise positioning.
• Added support of the combination tool reduces chatter and assures concentricity of the chamfer.
• Stocked with standard 90º included angle. 82º, 100º and 120º also available on special order.
• Special orders welcome for drills other than standard jobber drills–such as parabolic,
core, inserted, and solid carbide.
