Harvey Tool 803916 Spotting Drill 1/4 in 90 Deg Solid Carbide

Product Description

The HARVEY TOOL 803916 is a solid carbide spotting drill designed to create accurate center marks and entry points for follow-on drilling operations. It features a 90-degree point angle and a 0.2500-inch (1/4 inch) cutting diameter, with an overall length of 2.5 inches. The spiral flute geometry and Harvey Type I point promote precise spot location with minimal walking, reducing the need for center punching. This tool is used by machinists and CNC operators in general-purpose metal cutting applications where positional accuracy is critical before drilling to final diameter.

This spotting drill is suited for use on CNC machining centers, knee mills, and manual drill presses in job shop and production environments. The bright, uncoated finish makes it compatible with a wide range of workpiece materials in general-purpose applications. The straight cylindrical shank fits standard collets and drill chucks. It cuts in a right-hand direction and is single-ended for straightforward tooling setup.

Key Features

• Solid carbide construction for rigidity and wear resistance in general-purpose machining
• 90-degree point angle for accurate spotting and countersinking compatibility
• Harvey Type I point geometry minimizes drill walk at entry
• Spiral flute design with 2 flutes for chip evacuation during spotting
• Bright/uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank with 0.2500-inch diameter for standard collet and chuck compatibility

Compatibility

Designed as an OEM-style general-purpose spotting drill suitable for use in standard collet chucks and drill chucks accepting a 1/4-inch straight shank on CNC and manual machine tools.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Secure the straight shank firmly in a collet or chuck to the appropriate clamping depth to prevent pullout. Follow shop-standard speeds and feeds for carbide spotting drills based on workpiece material, and avoid applying excessive axial force that could chip the carbide point.
