Keo 906-000-211 Combo Drill Countersink Size 12 Hss

Product Description

The KEO 906-000-211 is a combination drill and countersink designed for creating pilot holes and countersink seats in a single operation. Built from high-speed steel with a bright uncoated finish, this tool handles both drilling and countersinking without a tool change. It features a 3/16 inch body diameter, a 1/16 inch drill point diameter, and a 60-degree included angle with a bell-style cutting edge. The 118-degree drill point angle suits general-purpose metalworking and fabrication applications. Right-hand cut geometry is standard for conventional spindle rotation on most drill presses and machining centers.

This combo drill countersink is suited for machine shops, maintenance facilities, and fabrication environments where countersink prep work is performed on metal stock. The size 12 trade designation fits standard toolholding setups. With an overall length of 1-7/8 inches, it is compact enough for tight fixturing situations. The double end type provides a second usable cutting end, extending tool life between replacements. Licensed machinists and tool-and-die professionals are the primary users of this style of combination tool.
