Keo 956-000-035 Spotting Drill 3/4 in 90 Deg Cobalt M-42

Product Description

The KEO 956-000-035 is a cobalt M-42 spotting drill designed to create accurate center locations and chamfered entry points for follow-on twist drills, reamers, and boring operations. Built with a 90-degree point angle and a 0.750-inch cutting diameter, this drill produces consistent, well-defined spots that guide subsequent tooling and reduce walking on flat or contoured workpiece surfaces. The M-42 cobalt steel construction provides elevated heat resistance and edge retention compared to standard HSS, making it a practical choice for production environments where tool life and dimensional repeatability matter. Licensed machinists and toolroom professionals are the typical end users.

This spotting drill is suited for general-purpose metal-cutting applications on manual mills, CNC machining centers, and drill presses. The 90-degree included angle is compatible with the majority of standard twist drills, making it a common choice when drilling into steel, cast iron, aluminum, and similar workpiece materials. The bright, uncoated finish makes tool wear easy to monitor during service. With an 8-inch overall length and a 0.750-inch straight cylindrical shank, it seats directly into standard collet chucks and drill chucks without adapters in most setups.

Key Features

• Cobalt M-42 tool steel for superior heat resistance and edge retention over standard HSS
• 90-degree point angle matches most common twist drill included angles for consistent pre-spotting
• 0.750-inch cutting diameter with spiral fluting and 2-flute geometry for efficient chip evacuation
• 1.875-inch flute length provides adequate depth for spotting without excessive dwell
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Right-hand cut, single-ended design for standard spindle rotation setups

Compatibility

Designed as a general-purpose spotting drill for use in standard straight-shank collet chucks and drill chucks accepting a 0.750-inch shank diameter.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before installing or changing tooling. Ensure the shank is fully seated and properly clamped in the chuck or collet before initiating a cut. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup.
