Accupro 35313 Corner Chamfer End Mill 0.25 in 3 Flute

Product Description

The ACCUPRO 35313 is a corner chamfer end mill designed for producing chamfered edges and angled profiles in a single pass. Built from powdered metal, it delivers consistent hardness and wear resistance across the cutting edge. The tool measures 0.25 inches in diameter with a 1.25-inch length of cut and a 3/8-inch shank diameter, making it well suited for compact workholding setups. With three flutes and a 30-degree helix angle, it balances chip evacuation with surface finish quality. The bright, uncoated finish keeps the tool ready for use on a broad range of materials without additional prep. Center-cutting geometry allows plunge entry directly into the workpiece.

This end mill is used in milling operations where a chamfer or angled edge must be machined into metal or similar machinable stock. The coarse pitch and right-hand cutting and flute direction make it a standard choice for general-purpose machining centers and manual mills. Its compact diameter suits detail work, narrow slots, and tight-feature parts where larger tooling cannot reach. Machinists and tool-and-die professionals working in job shops, production environments, or maintenance-and-repair machining will find this a straightforward drop-in for corner-break and deburring operations requiring a defined angle.

Key Features

• Powdered metal construction for consistent hardness and extended edge life
• Three-flute, 30-degree helix geometry balances chip removal and finish quality
• Center-cutting design allows direct plunge entry without pre-drilling
• Bright, uncoated finish compatible with a wide range of base materials
• Right-hand cut and right-hand flute direction for standard spindle operation
• Coarse pitch spacing reduces chip packing in deeper cuts

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 3/8-inch collet or end mill holders on vertical machining centers, knee mills, and CNC milling machines requiring a 0.25-inch corner chamfer end mill.

Installation Notes

Installation is performed by a machinist or tooling technician using a standard end mill holder or collet sized to the 3/8-inch shank diameter. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the minimum insertion depth recommended by the holder manufacturer before tightening. Verify runout with a dial indicator after installation to confirm concentricity before beginning a cut.
