Accupro 95168540 Corner Chamfer End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 95168540 is a solid carbide corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and non-ferrous workpieces. Built with a 4-flute, right-hand spiral geometry and a 45-degree chamfer angle, it produces consistent 0.0150-inch chamfer widths in a single pass. The AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in demanding cutting environments. At 4 inches overall length with a 2-1/8-inch reach length, it is well suited for machinists and tool-and-die professionals running CNC vertical or horizontal milling centers requiring extended-reach access.

This end mill fits standard 3/8-inch collet or end mill holders and is intended for use in production and job-shop milling applications. The centercutting design allows plunge entry, adding flexibility to the toolpath. Its micrograin carbide substrate and variable helix deliver improved chip evacuation and reduced chatter, making it appropriate for finishing operations on steel, stainless steel, and similar materials where edge quality is critical.

Key Features

• 45-degree chamfer angle with 0.0150-inch chamfer width for consistent edge preparation
• Solid micrograin carbide substrate for rigidity and wear resistance
• AlTiN coating for high-heat and abrasion resistance in ferrous cutting applications
• Variable helix geometry reduces chatter and improves surface finish
• Centercutting capability allows direct plunge entry into the workpiece
• Extended reach of 2-1/8 inches for access to recessed features

Compatibility

Designed for use in standard 3/8-inch collet chucks and end mill holders on CNC or manual milling machines. Intended as a direct-fit tool for applications requiring a single-end, right-hand cutting, 4-flute corner chamfer end mill with a 3/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures for collet or set-screw end mill holders. Ensure the machine spindle is fully stopped and the tool is secured to the manufacturer-recommended gauge length before operation. Verify runout with a dial indicator before cutting to confirm proper seating. Follow applicable shop safety protocols and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
