Accupro 35401 Corner Chamfer End Mill 0.25 in 3 Flute Tialn

Product Description

The ACCUPRO 35401 is a corner chamfer end mill designed for milling chamfers and beveled edges on workpiece corners with precision and repeatability. Built from powdered metal and coated with TiAlN, it handles elevated cutting temperatures and abrasive materials typical in production machining environments. The tool measures 0.25 inches in cutting diameter with a 1.25-inch length of cut and a 3/16-inch overall length of 3.0625 inches. Three flutes with a 30-degree right-hand helix provide chip clearance and surface finish quality. The centercutting geometry allows plunge entries as well as conventional peripheral milling passes.

This end mill is suited for use on CNC machining centers and manual knee mills handling ferrous and nonferrous materials where a chamfered corner profile is required. The 3/8-inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style holders commonly found in job shop and production floor setups. Fine pitch flute spacing supports smooth cutting action on steels, alloy steels, and hardened workpieces within the tool's rated hardness range. It is typically set up and operated by machinists and CNC programmers in precision fabrication and toolroom applications.

Key Features

• TiAlN coating increases heat resistance and extends tool life in dry or minimal-lubrication cutting conditions
• Powdered metal substrate provides uniform hardness and wear resistance throughout the tool body
• Centercutting design permits plunge milling without a pre-drilled pilot
• 30-degree right-hand helix promotes efficient chip evacuation and reduces cutting forces
• Fine pitch flute geometry delivers improved surface finish on corner chamfer profiles
• 3/8-inch shank accommodates widely available collet and end mill holder tooling

Compatibility

Designed as a direct-mount replacement or standard tooling addition for CNC machining centers and manual mills equipped with 3/8-inch collet or end mill holder systems requiring corner chamfer geometry.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the shank fully within the holder to the recommended engagement depth before tightening — insufficient engagement increases runout and reduces tool life. Verify spindle and holder concentricity with a dial indicator before beginning a cut. Always bring the spindle to a complete stop before changing or inspecting the tool.
