Keo 955-000-039 Spotting Drill 3/8 in 90 Deg Hss

Product Description

The KEO 955-000-039 is a single-ended spotting drill designed to create precise center starts for follow-on drilling operations. Built from high-speed steel with a bright uncoated finish, it features a 90-degree point angle and a 0.375-inch cutting diameter. The 2-inch overall length and straight cylindrical shank make it compatible with standard drill chucks and tool holders. With two spiral flutes and a right-hand cutting direction, this drill produces clean, accurate spot marks on a wide range of workpiece materials. Machinists and toolroom technicians rely on spotting drills like this to eliminate drill walk and ensure hole location accuracy before full-depth drilling.

This spotting drill suits general-purpose metalworking applications in job shops, machine shops, and maintenance environments. The 90-degree included angle aligns with common drill geometries, making it straightforward to use before standard twist drills. Its compact 2-inch OAL is appropriate for benchtop drill presses, CNC machining centers, and manual mills where clearance is a consideration. The 1-inch flute length provides adequate chip clearance for typical spotting depths.

Key Features

• 90-degree point angle aligns with standard general-purpose drill geometry for accurate spot starts
• High-speed steel construction provides hardness and wear resistance across common workpiece materials
• Bright uncoated finish suitable for general-purpose dry or light-lubrication cutting
• Two spiral flutes support chip evacuation during the spotting operation
• Straight cylindrical shank fits standard drill chucks and collet holders without adapters
• Right-hand cutting direction for use with conventional clockwise spindle rotation

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and straight-shank collet systems with a 3/8-inch bore capacity.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank fully in the chuck or collet and verify runout before use. Power down or lockout the spindle before changing tooling. Use appropriate cutting fluid or dry cutting conditions as dictated by the workpiece material and shop practice.
