Accupro 33084 Corner Chamfer End Mill 0.75in 4 Flute Tialn

Product Description

The ACCUPRO 33084 is a corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and non-ferrous workpieces. Built from powdered metal and coated with TiAlN for heat and wear resistance, this tool handles demanding cutting conditions at elevated speeds. It features a 0.75 inch cutting diameter, a 1.625 inch length of cut, and a 3.75 inch overall length with a 0.75 inch shank diameter. The 4-flute, 30-degree helix geometry promotes efficient chip evacuation and surface finish quality. Center-cutting capability allows plunge entry where required. Machinists and toolroom professionals running CNC mills or manual vertical mills are the primary users of this tool.

This end mill is suited for chamfering operations on steel, alloy steel, stainless, cast iron, and compatible non-ferrous materials in production and toolroom environments. The right-hand cut and right-hand flute direction make it a standard configuration for conventional vertical and horizontal milling setups. Fine pitch geometry supports smooth cutting action on medium to hard workpieces. It is appropriate for job shop, production floor, and maintenance machining applications where consistent chamfer geometry and edge quality are required.

Key Features

• TiAlN coating provides elevated heat resistance and extended tool life in ferrous cutting applications
• Powdered metal substrate delivers hardness and wear resistance beyond standard HSS
• 4-flute, 30-degree right-hand helix promotes efficient chip flow and smooth finish
• Center-cutting design permits plunge entry in addition to peripheral and chamfer cutting
• Fine pitch configuration supports controlled material removal on medium to hard workpieces
• Standard 0.75 inch shank fits common ER and side-lock toolholders without adaptation

Compatibility

Designed as a direct-fit replacement or standard toolroom end mill for CNC and manual vertical mills accepting a 0.75 inch shank. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Seat the shank fully in the collet or toolholder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before committing to production cuts, as excessive runout accelerates wear and degrades chamfer geometry.
