Accupro 12183536 Corner Radius End Mill 3/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12183536 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous metals. It features a 3/8 inch cutting diameter, a 0.03 inch corner radius, and a TiCN (titanium carbonitride) coating that improves wear resistance and tool life compared to uncoated carbide. The micrograin carbide substrate supports higher cutting speeds and feeds. With 4 right-hand spiral flutes and a centercutting geometry, this end mill handles slotting, profiling, and plunge operations. It is installed and operated by machinists and CNC tooling professionals in job shop and production environments.

This end mill is suited for milling operations requiring a controlled corner radius to reduce stress concentrations in pocketed or profiled workpieces. The long-length configuration, with a 1 inch length of cut and 4 inch overall length, provides reach for deeper pockets and stepped features. The single-end design and 3/8 inch shank diameter make it compatible with standard ER collet chucks, end mill holders, and hydraulic toolholders commonly found on CNC machining centers and manual knee mills.

Key Features

• 0.03 inch corner radius reduces stress risers and improves surface finish at part edges
• TiCN coating provides enhanced hardness and lubricity for extended tool life in steel and stainless applications
• Micrograin solid carbide substrate supports tight tolerances and high rigidity
• 4 right-hand spiral flutes with centercutting capability for slotting and plunge entry
• Long-length configuration with 1 inch LOC and 4 inch OAL for deeper reach
• Right-hand cutting direction compatible with conventional CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting 3/8 inch shank end mills via ER collet, end mill holder, or hydraulic toolholder.

Installation Notes

Installation should be performed by a qualified machinist following shop tooling procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank to the recommended insertion depth per the toolholder manufacturer's specification and torque the retention mechanism per toolholder guidelines. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and avoid premature tool wear.
