Keo 956-000-155 Spotting Drill 5/8 in Solid Carbide

Product Description

The KEO 956-000-155 is a solid carbide spotting drill designed to create accurate starter holes for subsequent drilling operations. With a 142-degree point angle and a 0.6250-inch cutting diameter, this tool establishes precise hole locations and reduces drill walk before the primary drill engages. The straight cylindrical shank and spiral flute geometry support consistent chip evacuation and stable tool holding in standard drill chucks or collet systems. Weighing 0.45 pounds, it suits bench-top drill presses, CNC machining centers, and manual milling setups alike. Machinists, toolroom operators, and production floor technicians working in metal fabrication and general manufacturing are the primary users.

This spotting drill is suited for general-purpose spotting operations across a range of workpiece materials where a bright, uncoated carbide tool is appropriate. It is sized for applications requiring a 5/8-inch diameter entry point with a shallow, defined seat for follow-up twist drills or specialty drills. The 1-1/8-inch flute length accommodates typical spotting depths without over-penetrating the workpiece. The right-hand cutting direction matches standard spindle rotation on conventional machining equipment. Single-ended construction means the tool is run from one end only, which is standard for this class of spotting drill.

Key Features

• 142-degree point angle centers accurately and reduces lateral deflection at drill start
• Solid carbide construction provides rigidity and wear resistance in production environments
• Bright/uncoated finish suits a wide range of general-purpose metal spotting applications
• Spiral flute design with 2 flutes promotes consistent chip clearance during spotting
• Straight cylindrical shank compatible with standard collets, chucks, and tool holders
• 3-1/2-inch overall length fits most standard spindle clearances on drill presses and machining centers

Compatibility

Designed as a general-purpose solid carbide spotting drill suitable for use in CNC machining centers, drill presses, and manual mills equipped with tooling compatible with a 5/8-inch straight cylindrical shank.

Installation Notes

This tool should be installed and operated by qualified machinists or toolroom technicians familiar with rotating cutting tool safety practices. Secure the shank fully within the collet or chuck to the recommended grip depth before running the spindle. Verify spindle rotation direction is right-hand before engaging the workpiece. Inspect the cutting edges for chips or wear before each use, as carbide is brittle and a damaged tool should not be run.
