Accupro 12182632 Corner Radius End Mill 5/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12182632 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 5/8 inch diameter with a 0.02 inch corner radius, a 1-1/4 inch length of cut, and a 40-degree helix angle. The micrograin carbide substrate is coated with TiCN (Titanium Carbonitride), which increases surface hardness and reduces friction during high-speed cutting. This is a single-end, centercutting tool with four flutes and right-hand cutting and flute direction. CNC machinists and tool and die professionals are the primary users.

This end mill is suited for side milling, slotting, and contouring operations on ferrous and non-ferrous materials where a controlled corner radius is required to reduce stress concentration in machined features. The centercutting geometry allows plunge cuts where needed. The 40-degree helix promotes efficient chip evacuation and smooth finishes. With a 3-1/2 inch overall length and a 5/8 inch shank diameter matching the cutting diameter, it fits standard ER and side-lock toolholders commonly found in vertical and horizontal machining centers.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance
• TiCN coating for increased surface hardness and reduced built-up edge
• 0.02 inch corner radius reduces stress risers and extends part life
• 40-degree helix angle promotes chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut, right-hand spiral, four-flute configuration for general milling applications

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 5/8 inch bore milling toolholders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated torque wrench and appropriate collet or toolholder to secure the 5/8 inch shank; do not overtighten side-lock screws directly against the shank without a flat. Verify runout with a dial indicator after seating to confirm concentricity before beginning a cut.
