Harvey Tool 39900-C3 Spotting Drill 140 Deg Solid Carbide

Product Description

The HARVEY TOOL 39900-C3 is a solid carbide spotting drill designed to create accurate starter spots for follow-up drilling operations. The 140-degree point angle reduces walking and improves hole location accuracy on flat and angled workpiece surfaces. At 1.5 inches overall length with a 0.100-inch cutting diameter and 0.125-inch straight cylindrical shank, this tool fits standard drill chucks and collet holders common in CNC machining centers and manual mills. The AlTiN coating provides elevated heat resistance and extended tool life in ferrous and high-hardness materials. Two spiral flutes evacuate chips efficiently during the spotting pass.

This spotting drill is suited for general-purpose metal cutting applications in job shops, production machining, and toolrooms. It is used ahead of twist drills, insert drills, and boring operations to establish precise hole centers and eliminate pilot deviation. The short flute length of 0.300 inches and compact overall length make it appropriate for confined setups and close-tolerance work where rigidity matters. Machinists and CNC operators working with steel, stainless, cast iron, and similar materials will find this a dependable station in a tool carousel or manual setup.

Key Features

• 140-degree point angle reduces drill walk and improves positional accuracy at hole entry

Compatibility

Designed as a general-purpose spotting drill for use with standard 0.125-inch straight shank collets and drill chucks in CNC machining centers, knee mills, and similar machine tools.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or CNC operator. Secure the shank fully in a collet or drill chuck to the recommended grip depth before running the spindle. Verify spindle speed and feed rate against the tool manufacturer recommendations for the workpiece material and coating before beginning a cut. Inspect the cutting edge and coating condition before each use and replace the tool if chipping or wear is observed.
