Harvey Tool 20960 Tapered End Mill 0.06 in Solid Carbide

Product Description

The HARVEY TOOL 20960 is a solid carbide tapered end mill designed for precision milling in tight geometries and miniature component work. It features a 0.06-inch small end diameter, a 0.6-inch length of cut (LOC), and a 3-degree taper angle per side. The three-flute geometry balances chip evacuation with wall finish quality. At 3 inches overall length with a 3/16-inch shank diameter, this tool fits standard collet systems used in CNC machining centers and high-speed spindles. The bright, uncoated finish suits ferrous and non-ferrous materials where coating interaction or regrinding is a consideration. Machinists and tooling engineers working on mold cavities, tapered slots, and draft-angle features will find this geometry directly applicable.

This end mill fits applications in die and mold machining, aerospace component finishing, and medical device manufacturing where draft angles and tapered wall features are required. The miniature small-end diameter makes it suited for fine-detail passes in deep pockets and narrow cavity walls. Its solid carbide construction handles the rigidity demands of high-speed finishing cuts in hardened or abrasive materials. It is part of Harvey Tool's Miniature End Mills - Tapered - Square series, built specifically for small-diameter, high-precision CNC work.

Key Features

• 3-degree taper angle per side for controlled draft on cavity walls and tapered slots
• 0.06-inch small end diameter enables fine-detail milling in miniature features
• Solid carbide construction provides rigidity and wear resistance at high cutting speeds
• Three-flute design balances chip clearance and surface finish in finish-pass applications
• 30-degree helix angle promotes smooth cutting action and reduced cutting forces
• Bright uncoated finish allows direct use on a broad range of materials and supports regrinding

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and high-speed milling spindles accepting a 3/16-inch round shank via ER collet or equivalent toolholding system.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in an e-stop or locked-out state. Confirm collet bore matches the 3/16-inch shank diameter before clamping. Avoid side-loading beyond the rated geometry of the tool; the small end diameter is sensitive to deflection under aggressive radial cuts. Follow shop-standard runout checks after seating to protect both the tool and the workpiece.
