Keo 955-000-081 Spotting Drill 1.25 in 90 Deg Hss

Product Description

The KEO 955-000-081 is a single-ended spotting drill designed to create accurate starter locations for twist drills, reamers, and boring tools. Built from high-speed steel with a bright, uncoated finish, it features a 90-degree point angle that produces a clean, precise cone seat to guide follow-on tools and reduce walking. The 1.25-inch cutting diameter and 2-inch flute length handle general-purpose spotting on a range of ferrous and non-ferrous materials. This tool is installed in manual mills, CNC machining centers, and drill presses by machinists and tool-and-die professionals.

This spotting drill is suited for production and maintenance machining environments where accurate hole location is critical before drilling, reaming, or countersinking operations. The straight cylindrical shank accepts standard collet chucks and drill chucks sized for 1.25-inch shanks. Its general-purpose rating makes it appropriate for use in job shops, manufacturing cells, and MRO operations across a wide range of workpiece materials including mild steel, aluminum, brass, and plastics.

Designed as a general-purpose spotting drill for use in standard collet chucks and drill chucks accepting a 1.25-inch straight cylindrical shank, compatible with manual and CNC mill spindles and drill presses configured for that shank diameter.

Installation Notes

A licensed machinist or qualified operator should install this tool with the machine spindle fully stopped and locked out per applicable safety procedures. Verify chuck or collet runout before operation to maintain location accuracy. Use appropriate cutting fluid for the workpiece material when operating at higher spindle speeds. Do not force the tool into cut; allow the geometry to establish the spot at a controlled feed rate.
