Keo 956-000-133 Spotting Drill 5/16 in 90 Deg Solid Carbide

Product Description

The KEO 956-000-133 is a solid carbide spotting drill designed to create precise, centered starting points for follow-up drilling operations. Built with a 90-degree point angle and a 5/16-inch (0.3125 inch) cutting diameter, this tool establishes accurate hole locations and reduces drill wander on flat and angled surfaces. The bright, uncoated finish suits general-purpose machining across a range of workpiece materials. With an overall length of 2.5 inches and a 1/2-inch straight-cylindrical shank, it mounts securely in standard drill chucks and collet holders used in machining centers, manual mills, and drill presses. Machinists and tool-and-die professionals install this drill as a preparatory step before reaming, tapping, or deep-hole drilling.

This spotting drill is suited for general-purpose spotting and center-marking applications in both production and job-shop environments. The 2-flute spiral flute design promotes chip clearance during the spotting pass. The right-hand cutting direction is compatible with standard CNC and manual spindle rotation. Typical applications include spotting holes in steel, aluminum, cast iron, and similar materials where precise hole location is required prior to finish drilling or boring operations.

Key Features

• 90-degree point angle for accurate hole spotting and reduced drill wander
• Solid carbide construction for rigidity and wear resistance in general-purpose machining
• Bright/uncoated finish suitable for a broad range of workpiece materials
• 2-flute spiral flute geometry for efficient chip evacuation during spotting passes
• Straight-cylindrical 1/2-inch shank fits standard chucks and collet holders
• Single-ended, right-hand cut for use with standard spindle rotation

Compatibility

Designed as a general-purpose spotting drill compatible with CNC machining centers, manual milling machines, and drill presses equipped with 1/2-inch or larger chuck or collet systems.

Installation Notes

This tool is installed by machinists in milling and drilling setups. Power down and lock out the machine spindle before changing tooling. Secure the shank fully in the collet or chuck to the recommended grip depth before operation. Inspect the cutting edges for chips or wear before each use, as carbide tools can fracture if run at improper speeds or feeds for the workpiece material.
