Harvey Tool 37510 Spotting Drill 0.1563in 90pt Solid Carbide

Product Description

The HARVEY TOOL 37510 is a solid carbide spotting drill designed to accurately locate and start holes before drilling operations. With a 90-degree point angle and a 0.1563-inch cutting diameter, it creates a precise, centered seat that guides twist drills and reduces walk-off on flat or curved workpiece surfaces. The Harvey Type II point geometry and spiral flute design promote clean chip evacuation and consistent positioning. At 2 inches overall length with a 0.1875-inch straight-cylindrical shank, this tool suits standard drill chucks and collet systems on CNC machining centers and manual mills alike. It ships uncoated with a bright finish.

This spotting drill is intended for general-purpose spotting and centering applications across a wide range of workpiece materials. The single-ended, right-hand-cut configuration makes it straightforward to run at typical CNC spotting parameters. The compact 0.375-inch flute length keeps the cutting zone rigid and minimizes deflection, which is especially important when working with close-tolerance hole patterns. Machinists and tool-and-die professionals who require repeatable, burr-free spot locations will find this an appropriate choice for production and job-shop environments.

• Bright/uncoated finish suitable for a wide range of base materials
• Straight-cylindrical shank compatible with standard collets and drill chucks

Compatibility

Designed as a general-purpose solid carbide spotting drill compatible with CNC machining centers, knee mills, and drill presses equipped with collet or drill-chuck toolholding systems accepting a 0.1875-inch straight-cylindrical shank.

Installation Notes

Installation and operation of this tool should be performed by qualified machinists familiar with cutting tool setup and CNC or manual mill operation. Secure the shank fully within the collet or chuck before running the spindle, and verify runout is within acceptable limits for the application. Power down and lock out the machine before changing or inspecting tooling. Always consult the machine tool and cutting tool manufacturer guidelines for appropriate speeds, feeds, and depth-of-cut parameters.
