Harvey Tool 55812-C3 Spotting Drill 3/16 in 90deg Carbide Altin

Product Description

The HARVEY TOOL 55812-C3 is a solid carbide spotting drill designed to create precise, accurate starting points for follow-up drill operations. Built to a 90-degree point angle and measuring 3/16 inches in cutting diameter, this single-ended tool delivers consistent spot depth and location accuracy on a wide range of workpiece materials. The AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, extending tool life in production environments. With a 4-inch overall length and a straight cylindrical shank, it seats securely in standard drill chucks and collet holders. This tool is suited for machinists, toolmakers, and CNC operators working in job shop and production settings.

The 55812-C3 is intended for general-purpose spotting and centering applications across ferrous and non-ferrous materials. The 5/8-inch spiral flute length and 90-degree Harvey Type II point geometry provide clean entry without walking, making it a practical choice for precision hole location work on machining centers, drill presses, and manual mills. The right-hand cutting direction is standard for conventional spindle rotation setups.

Key Features

• 90-degree point angle for accurate drill spotting and chamfering in a single operation
• Solid carbide construction for rigidity and wear resistance in demanding cut conditions
• AlTiN coating improves heat resistance and extends tool life at higher surface speeds
• Harvey Type II point geometry minimizes deflection and walking at entry
• Spiral flute design with 2 flutes promotes chip evacuation during spotting operations
• Straight cylindrical shank compatible with standard collet chucks and drill holders

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks, ER collets, and similar straight-shank toolholding systems on CNC machining centers, drill presses, and manual milling machines.

Installation Notes

This tool is installed by machinists or CNC operators in a compatible straight-shank collet or chuck system. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after installation to confirm concentricity. Follow the machine manufacturer's recommended speeds and feeds for the workpiece material and coating type.
