Accupro 12181542 Corner Radius End Mill 3/4 in 2 Flute Ticn

Product Description

The ACCUPRO 12181542 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), this single-end tool delivers extended tool life and wear resistance in demanding cutting environments. The 0.015-inch corner radius reduces stress concentration at the cutting edge, helping to produce consistent, burr-free workpiece corners. With a 40-degree helix angle and right-hand cutting direction, it is suited for machinists and tool and die professionals running CNC machining centers or manual mills at moderate to high feed rates.

This end mill is appropriate for use in job shops, tool rooms, and production machining environments handling steel, stainless, cast iron, and similar materials where TiCN coatings provide a performance advantage. The centercutting geometry allows for direct plunge entry when required. The 3/4-inch shank diameter fits standard ER and side-lock tool holders common in vertical and horizontal machining centers. It is sold as a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than indexed.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in ferrous and abrasive materials
• 0.015-inch corner radius reduces edge chipping and improves corner finish
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge milling
• Right-hand flute direction and cutting action for standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/4-inch shank tool holders used in CNC machining centers and manual milling machines requiring a corner radius end mill geometry.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Verify that the tool holder bore and collet are clean and free of chips before seating the shank. Confirm runout with a dial indicator before beginning production cuts to avoid premature tool wear or workpiece damage.
