Accupro 95168431 Corner Chamfer End Mill 0.5in 4 Flute Altin

Product Description

The ACCUPRO 95168431 is a solid carbide corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and non-ferrous materials. Built from micrograin solid carbide, it carries an AlTiN coating for heat resistance and extended tool life at elevated cutting speeds. The 4-flute, single-end geometry features a 45-degree chamfer angle with a 0.0150-inch chamfer width and a variable helix with right-hand spiral flutes, reducing chatter and improving surface finish. At 0.5 inches in diameter with a 1.25-inch length of cut and 3-inch overall length, this tool fits standard toolholders used across CNC mills and machining centers in production and job-shop environments.

This end mill is suited for chamfering, deburring, and edge preparation on machined parts in metalworking applications. The centercutting design allows plunge entry, adding flexibility for interrupted cut entries. Typical users include CNC machinists and tool-and-die professionals running steel, stainless, cast iron, and high-temperature alloys. The AlTiN coating supports dry and semi-dry cutting conditions, reducing coolant dependency in high-speed applications. A right-hand cutting direction pairs with standard CNC spindle rotation without modification.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in ferrous materials
• 45-degree chamfer angle with 0.0150-inch chamfer width for consistent edge geometry
• Variable helix spiral flutes reduce vibration and improve chip evacuation
• Centercutting capable — allows direct plunge entry
• Right-hand flute direction and cutting direction compatible with standard CNC spindles

Compatibility

Designed as an OEM-style replacement and standard tooling selection for CNC machining centers and manual mills accepting a 0.5-inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Power down and lock out the spindle before changing tooling. Seat the 0.5-inch shank fully into the collet or toolholder to the recommended gauge-line depth and torque the retention hardware per the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each run.
