Keo 956-000-149 Spotting Drill 3/8 in Solid Carbide

Product Description

The KEO 956-000-149 is a solid carbide spotting drill designed to create precise starter holes for follow-on drilling operations. Built with a 142-degree point angle, it produces accurate center locations that reduce walking and improve hole position repeatability on a wide range of workpiece materials. The 3/8 inch cutting diameter and straight cylindrical shank make it compatible with standard drill chucks and collet holders. With an overall length of 2.5 inches and a 0.875 inch flute length, this tool is suited for close-tolerance spotting work in machine shop and production environments. Machinists, tool-and-die makers, and CNC operators are the primary users.

This spotting drill is intended for general-purpose spotting applications on CNC machining centers, drill presses, and manual mills. It is well suited for creating lead-in points before twist drilling, countersinking, or reaming in metalworking, fabrication, and job shop settings. The bright uncoated finish keeps regrinding straightforward, and the right-hand spiral flute geometry provides efficient chip clearance during the spotting pass. Two flutes with right-hand cutting direction are standard for this tool type.

Key Features

• 142-degree point angle for accurate spot location and reduced drill walk
• Solid carbide construction for rigidity and wear resistance in metalworking applications
• Bright uncoated finish allows easy visual inspection and simplifies regrinding
• Straight cylindrical shank fits standard drill chucks and ER collet systems
• Two-flute right-hand spiral geometry promotes clean chip evacuation
• Single-ended design for consistent tool setting in production setups

Compatibility

Designed as a general-purpose spotting drill for use in standard 3/8 inch straight-shank toolholders, drill chucks, and ER collet systems on CNC machining centers, drill presses, and manual mills.

Installation Notes

Install the shank fully and evenly into a clean, properly sized collet or chuck before tightening to the toolholder manufacturer's specified clamping torque. Ensure the spindle and workpiece are secured before starting the machine. Use appropriate cutting speeds and feeds for solid carbide spotting drills based on workpiece material. Inspect the cutting point for chipping or wear before each use, as carbide tools can fail suddenly if operated with damaged geometry.
