Harvey Tool 912286-C6 Tapered End Mill 3 Flute Solid Carbide

Product Description

The HARVEY TOOL 912286-C6 is a solid carbide tapered end mill designed for precision milling in tight-tolerance machining applications. Built with a square end geometry and a 1.8-degree taper angle per side, this tool is suited for producing angled walls, draft features, and contoured profiles in a single pass. The small end diameter measures 0.3 inches with a 0.9-inch length of cut, providing a compact cutting envelope that excels in confined areas and intricate part geometries. With 3 flutes and a 30-degree helix angle, it balances chip evacuation with cutting efficiency in both ferrous and non-ferrous materials. Machinists and CNC programmers in job shops, tool rooms, and production environments will find this tool well suited for finish milling and profile work.

This tapered end mill fits into the HARVEY TOOL Miniature End Mills - Tapered - Square series, targeting small-scale and precision machining scenarios. It is appropriate for use in vertical machining centers and CNC mills where fine detail work or draft-angle milling is required. The 3/8-inch shank diameter accommodates standard collet and end mill holders, and the 2.5-inch overall length provides adequate reach without excessive deflection. Typical applications include mold and die work, aerospace components, and medical device parts where accurate tapered walls are critical.

Key Features

• 1.8-degree taper angle per side for precise draft-wall and angled-cavity milling
• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Square end geometry produces sharp, defined floor transitions
• 3 flutes with 30-degree helix angle for balanced chip flow and surface finish
• 0.3-inch small end diameter suits miniature and close-tolerance work
• 3/8-inch shank fits standard collet chucks and end mill holders

Compatibility

Designed as an OEM-style replacement and standard production tool within the HARVEY TOOL Miniature End Mills - Tapered - Square series, compatible with CNC machining centers using standard 3/8-inch collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification to prevent pullout during cutting. Inspect the cutting edges for chips or wear before each use, as carbide tooling can fail suddenly if run with pre-existing damage.
