Harvey Tool 39890-C3 Spotting Drill 0.09 in 2-flute Carbide

Product Description

The HARVEY TOOL 39890-C3 is a 2-flute solid carbide spotting drill designed to accurately locate and start holes before drilling operations. Built to Harvey Type I point geometry, it features a 140-degree point angle that reduces walking and delivers consistent center marks across a wide range of materials. The AlTiN coating provides thermal resistance and extended tool life in ferrous and high-temperature alloy applications. At 0.09 inches in cutting diameter and 1.5 inches overall length, this compact drill suits close-tolerance machining work in both production and job-shop environments.

The 39890-C3 is suited for general-purpose spotting operations on CNC machining centers and manual mills. The straight cylindrical shank at 0.125 inches diameter fits standard collets and toolholders common to light-duty spindles. Its single-ended spiral-flute design makes it appropriate for spot-drilling prior to twist drilling, reaming, or tapping in steel, stainless, cast iron, and similar materials. Machinists and toolroom technicians working in aerospace, automotive, and general fabrication shops are the primary users.

Key Features

• 140-degree Harvey Type I point angle reduces drill walk and improves hole location accuracy
• AlTiN coating provides heat resistance and wear protection in ferrous and high-alloy materials
• Solid carbide construction delivers rigidity and tool life beyond high-speed steel alternatives
• 2-flute spiral design clears chips efficiently in short spotting cuts
• Straight cylindrical shank at 0.125 inches fits standard collet systems
• Single-ended design for straightforward toolholder setup

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard straight-bore collets and toolholders accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before loading or changing tooling. Seat the shank fully and evenly in the collet before tightening to prevent runout. Confirm spindle speed and feed rate are appropriate for the workpiece material and cutting diameter before starting the operation.
