Accupro 14799504 Corner Radius End Mill 0.055 in 2 Flute

Product Description

The ACCUPRO 14799504 is a solid carbide corner radius end mill designed for precision milling of small-diameter features. Built from micrograin carbide with a bright/uncoated finish, it measures 0.055 inches in diameter with a 0.005 inch corner radius and a 1.5 inch overall length. The 2-flute, right-hand spiral design supports centercutting capability, making it suited for both plunge entry and peripheral milling passes. The miniature series designation indicates this tool targets fine-feature work where tight tolerances and small step-overs are required. Machinists and tool-and-die professionals working on precision components, molds, or intricate part geometries are the primary users of this tool.

This end mill fits residential and commercial machine shop applications where small-diameter, tight-tolerance cuts are needed. It is well suited for CNC machining centers and manual mills operating on aluminum, non-ferrous metals, plastics, and similar materials at the miniature scale. The 0.165 inch length of cut, 1/8 inch shank diameter, and single-end configuration make it a direct fit for collet-style toolholders commonly used in precision machining setups.

Key Features

• 0.055 inch mill diameter with mill diameter tolerance of +0.000 / -0.001 inches for tight dimensional control
• 0.005 inch corner radius reduces stress concentrations at the cutting edge
• Micrograin solid carbide construction provides wear resistance and edge retention in fine-feature applications
• 2-flute right-hand spiral geometry supports chip evacuation in miniature-scale cuts
• Centercutting design allows direct plunge entry without pre-drilled pilot holes
• Bright/uncoated finish compatible with cutting fluids and lubricants without coating interaction concerns

Compatibility

Designed as a miniature-series replacement or standard tooling selection for CNC machining centers and manual mills equipped with 1/8 inch collet or end mill holders requiring a single-end corner radius end mill.

Installation Notes

Installation is performed by a machinist or tooling technician. The tool should be secured in a properly sized 1/8 inch collet or end mill holder and torqued according to the toolholder manufacturer specifications before use. Verify spindle runout is within acceptable limits for miniature tooling before beginning a cut, as excessive runout at this diameter will accelerate tool wear and reduce dimensional accuracy. Always confirm the workholding setup is rigid and that the machine is at a full stop before changing tooling.
