Accupro 12179352 Corner Radius End Mill 3/8 in Solid Carbide

Product Description

The ACCUPRO 12179352 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/8 inch diameter with a 0.015 inch corner radius and a 5/8 inch length of cut, making it well suited for profiling, slotting, and peripheral milling where edge strength and surface finish are critical. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hard alloy cutting. With three right-hand spiral flutes and a centercutting geometry, this end mill handles both plunge entry and conventional milling paths. It is installed and operated by machinists and CNC tooling professionals in job shop and production environments.

This end mill is appropriate for use on CNC machining centers and manual mills cutting steel, stainless steel, cast iron, and high-temperature alloys where corner rounding on part features is required. The single-end design with a 3/8 inch shank diameter fits standard ER and mechanical collet toolholding systems. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces in medium to high-feed applications. Micrograin carbide substrate provides rigidity and wear resistance in demanding production runs.

Key Features

• 0.015 inch corner radius reduces stress concentration at milled edges and improves part durability
• AlTiN coating delivers high oxidation resistance and hardness for dry or minimal-lubrication cutting
• Micrograin solid carbide substrate provides superior rigidity and edge retention over tool steel alternatives
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• 40-degree right-hand helix promotes chip evacuation and smooth surface finish
• Single-end construction with 3/8 inch shank fits standard collet and endmill holders

Compatibility

Designed as an OEM-style cutting tool for use in standard 3/8 inch collet or mechanical endmill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before engaging the workpiece, as excessive runout accelerates edge wear and degrades corner radius accuracy.
