Keo 955-000-025 Spotting Drill 5/16 in 118 Pt Hss

Product Description

The KEO 955-000-025 is a single-ended spotting drill designed to accurately locate and start holes before a follow-up twist drill or boring operation. Manufactured from high-speed steel with a bright uncoated finish, it features a 118-degree drill point angle that produces a clean, precise indentation to guide subsequent tooling. The cutting diameter is 0.3125 inches (5/16 inches), the overall length is 1.5 inches, and the straight cylindrical shank diameter is 0.3125 inches. It cuts in a right-hand direction with a two-flute spiral configuration suited for general-purpose spotting work. Machinists, tool-and-die workers, and fabrication tradespeople are the primary installers.

This spotting drill is intended for use in general-purpose machining applications where accurate hole location is critical prior to drilling, reaming, or tapping. It fits standard drill chucks and collet holders that accept a 5/16-inch straight shank. The 5/8-inch flute length provides adequate chip clearance for the shallow depth inherent to spotting operations. It is appropriate for use in bench drill presses, knee mills, CNC machining centers, and manual lathes across light fabrication, maintenance, and production environments.

Key Features

• 118-degree drill point angle for accurate hole location and minimal wandering
• High-speed steel construction provides durability across a broad range of workpiece materials
• Bright uncoated finish - no coating buildup to affect dimensional accuracy
• Two-flute spiral geometry promotes chip evacuation during spotting operations
• Straight cylindrical shank accepts standard drill chucks and ER collets
• Single-ended design for straightforward replacement when point dulls

Compatibility

Designed as a general-purpose spotting drill compatible with any drill press, milling machine, or CNC machining center equipped with a chuck or collet holder sized for a 5/16-inch straight shank.

Installation Notes

A licensed machinist or qualified fabrication technician should install and operate this tooling. Always power down and lock out the machine spindle before changing or inspecting cutting tools. Secure the shank fully within the chuck or collet to the manufacturer-recommended engagement depth before operation. Inspect the drill point for wear or chipping before each use and replace the tool when point geometry is compromised to avoid inaccurate spot locations.
