Accupro 95168469 Corner Radius End Mill 0.2813 in 4 Flute

Product Description

The ACCUPRO 95168469 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. The cutter measures 0.2813 inches in diameter with a 0.0150-inch corner radius, a 0.6250-inch length of cut, and a 2.5-inch overall length. A 5/16-inch shank diameter keeps it compatible with standard collet systems. The AlTiN coating provides thermal resistance and extended tool life in high-speed and dry machining environments. Four flutes and a variable helix geometry reduce harmonics and improve chip evacuation. Centercutting capability allows plunge entry. Intended for use by machinists and CNC operators in job shop and production environments.

This end mill is suited for finish and semi-finish milling, slotting, profiling, and ramping operations on steel, stainless steel, cast iron, and hard alloys. The right-hand cutting direction and right-hand spiral flute geometry are standard for conventional CNC machining center setups. The regular-length flute design keeps deflection low, making it appropriate for tight-tolerance work where dimensional accuracy is critical. The micrograin carbide substrate supports higher surface speeds compared to standard carbide grades.

Key Features

• 0.2813-inch mill diameter with a 0.0150-inch corner radius for edge strength and surface finish
• AlTiN coating for heat resistance and extended tool life in dry or minimal-lubrication cutting
• Variable helix flute geometry reduces chatter and vibration during cut
• Centercutting design allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate for rigidity and wear resistance
• 4-flute, single-end configuration with right-hand cut and right-hand spiral

Compatibility

Designed as a standard shank solid carbide corner radius end mill compatible with 5/16-inch collet chucks and end mill holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully and evenly in a clean, undamaged collet or tool holder to the specified engagement depth. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates wear and degrades surface finish.
