Harvey Tool 839608-C3 Spotting Drill 1/8 in Carbide Altin

Product Description

The HARVEY TOOL 839608-C3 is a solid carbide spotting drill engineered to create precise, accurately located starter points for follow-on drilling operations. Built to a 130-degree point angle with a Harvey Type I point geometry, it establishes clean, centered entry holes that improve positional accuracy and reduce walking on subsequent drill passes. The tool measures 0.125 inches in cutting diameter with an overall length of 1.5 inches and a flute length of 0.375 inches. An AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in demanding materials. This drill is installed and used by machinists and CNC operators in precision machining environments.

This spotting drill is suited for general-purpose spotting applications across a range of workpiece materials where accurate hole location is critical. The 0.125-inch diameter and 1.5-inch overall length make it appropriate for compact or shallow-access features in both manual machining and CNC setups. The straight cylindrical shank allows direct chuck or collet mounting without adapters. Right-hand cutting direction is standard for conventional spindle rotation in most machining centers and lathes.

Key Features

• 130-degree point angle for accurate hole spotting with minimal radial force
• Harvey Type I point geometry for repeatable center location
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for improved heat resistance and extended tool life
• Spiral flute, two-flute design with right-hand cut
• Straight cylindrical shank for direct chuck or collet mounting

Compatibility

Designed as a general-purpose spotting drill compatible with standard CNC machining centers, mills, and lathes equipped with a collet or drill chuck accepting a 0.125-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators following standard machine shop practices. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Seat the shank fully and evenly in the collet or chuck and verify runout before beginning a cut. Follow applicable machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
