Harvey Tool 39862-C3 Spotting Drill 1/16 in Solid Carbide

Product Description

The HARVEY TOOL 39862-C3 is a solid carbide spotting drill designed to create precise starter holes for subsequent drilling operations. With a 1/16 inch (0.0625 inch) cutting diameter and a 140-degree point angle, it accurately centers hole locations and reduces drill walking on flat or angled surfaces. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in ferrous materials. At 1.5 inches overall length with a 0.186 inch flute length, this is a compact tool suited for close-tolerance work on CNC machining centers and manual mills in production and job-shop environments.

This spotting drill is intended for general-purpose spotting and centering applications across a range of workpiece materials. Its short flute geometry and rigid solid carbide construction minimize deflection when establishing hole entry points. The straight cylindrical shank fits standard collet chucks and drill chucks with a 1/8 inch bore. It is well suited for machinists and toolroom technicians working with tight positional tolerances on small-diameter hole patterns in metal fabrication, mold making, and precision machining applications.

Key Features

• 140-degree point angle for accurate spotting and reduced thrust at hole entry
• AlTiN coating provides elevated heat and wear resistance in ferrous and hard materials
• Solid carbide construction delivers rigidity and dimensional stability in small-diameter tooling
• Spiral flute geometry with 2 flutes aids chip evacuation during spotting operations
• Single-ended design with straight cylindrical shank for direct collet or drill chuck mounting
• Harvey Type I point geometry optimized for spotting and countersinking pre-drill locations

Compatibility

Designed as a general-purpose spotting drill compatible with CNC machining centers, knee mills, and drill presses using standard 1/8 inch straight-shank collet or drill chuck toolholders.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tool practices. Ensure the machine spindle is fully stopped and the tool is securely clamped in the toolholder before beginning any setup. Verify runout at the shank before use, as excessive runout on small-diameter carbide tools can cause breakage. Follow applicable shop safety procedures and machine manufacturer guidelines for spindle speed and feed rate selection.
