Harvey Tool 11430-C3 Spotting Drill 0.03in 90deg Solid Carbide

Product Description

The HARVEY TOOL 11430-C3 is a solid carbide spotting drill designed to create accurate, centered starting points for follow-on drilling operations. With a 90-degree point angle and a 0.03-inch cutting diameter, this tool produces precise cone-form seats that guide twist drills and reduce walking on hard or slick workpiece surfaces. The Harvey Type I point geometry and AlTiN coating support use across a broad range of materials, including steels, stainless alloys, and hardened workpieces. At 1.5 inches overall length with a 0.125-inch straight cylindrical shank, it fits standard collet chucks and precision tool holders used in CNC and manual machining setups.

This spotting drill is suited to general-purpose machining environments where hole-location accuracy is critical before full-depth drilling. The 0.09-inch flute length and spiral two-flute design allow for efficient chip clearance in shallow spotting applications. Machinists working on precision components in job shops, production cells, or toolroom environments will find this drill appropriate for ferrous and non-ferrous materials where a clean, accurate drill seat is required before proceeding with the primary drill.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 90-degree Harvey Type I point angle for accurate spotting and countersink seat formation
• AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials
• 0.125-inch straight cylindrical shank fits standard collets and precision tool holders
• Two-flute spiral design promotes chip evacuation in shallow spotting cuts
• Single-ended, right-hand cut configuration for conventional CNC and manual spindle setups

Compatibility

Designed as a general-purpose spotting drill for use in CNC machining centers and manual mills where a 0.125-inch shank and 90-degree point angle are required for pre-drill spotting operations.

Installation Notes

Installation and use of this tool is performed by machinists in CNC or manual machining environments. Secure the shank in a properly sized collet or drill chuck and verify runout before use, as excessive runout will compromise hole-location accuracy. Set spindle speeds and feeds according to the workpiece material and tool manufacturer recommendations for solid carbide spotting drills. Do not use this tool as a reamer, countersink, or full-depth drill beyond its rated flute length.
