Harvey Tool 37510-C3 Spotting Drill 0.1563 in 90 Pt Carbide

Product Description

The HARVEY TOOL 37510-C3 is a solid carbide spotting drill designed to accurately start holes and guide twist drills, reamers, and other rotary cutting tools. It features a 90-degree point angle, a 0.1563-inch cutting diameter, and a 2-inch overall length. The AlTiN coating improves surface hardness and heat resistance, making it suitable for higher-speed applications in ferrous and non-ferrous materials. This is a single-ended tool with a straight cylindrical shank and a two-flute spiral design. Machinists and tool-and-die professionals install this type of drill in CNC machining centers and manual mills where precise hole location is critical.

This spotting drill fits general-purpose machining applications in job shops, production floors, and tool rooms. Its 0.1875-inch straight shank mounts directly into standard collets and drill chucks. The 0.375-inch flute length keeps the cutting zone compact, which supports rigidity and reduces deflection when starting holes in steel, cast iron, aluminum, and similar workpiece materials. It is suited for use in both vertical machining centers and bench-top milling machines where repeatable hole positioning is required.

Key Features

• 90-degree point angle for accurate hole spotting and countersink starting
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• Two-flute spiral geometry promotes chip evacuation during spotting operations
• Harvey Type II point geometry designed for precise center location
• Straight cylindrical shank fits standard collets and drill chucks

Compatibility

Designed as an OEM-style spotting drill for use in standard CNC machining centers, knee mills, and similar machine tool setups that accept a 0.1875-inch straight shank toolholder or collet.

Installation Notes

A qualified machinist should install this tool in a properly sized collet or drill chuck, ensuring the shank is fully seated and the runout is within acceptable tolerance before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Do not use this tool as a reamer or end mill. Follow all machine guarding and PPE requirements per OSHA and shop safety standards.
