Accupro 12182670 Corner Radius End Mill 3/4in 4 Flute Ticn

Product Description

The ACCUPRO 12182670 is a solid carbide corner radius end mill designed for precision milling operations in metal-cutting applications. It features a 3/4-inch diameter, a 1-1/2-inch length of cut, and a 0.0450-inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and a smooth surface finish. A TiCN coating adds hardness and wear resistance, making this end mill well suited for ferrous and non-ferrous materials. It is installed and used by machinists and CNC programmers in production and job-shop environments.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a corner radius profile is required to produce blended fillets, reduce tool breakage at corners, or meet part geometry requirements. The single-end, centercutting design allows plunge entry as well as conventional side milling. The 3/4-inch shank diameter fits standard ER, CAT, BT, and HSK toolholders of the appropriate bore size. It is a practical choice for steel, stainless steel, cast iron, and similar materials where edge durability and dimensional consistency are priorities.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• TiCN coating increases surface hardness and reduces built-up edge
• 0.0450-inch corner radius reduces stress at cutting edges and extends tool life
• 40-degree helix angle promotes chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry without a pilot hole
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 3/4-inch bore toolholding systems used in CNC and manual milling applications.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. The shank should be cleaned and seated fully into the toolholder to the recommended gauge line before tightening. Verify runout with a dial indicator after installation and before cutting to confirm proper seating and avoid premature wear or breakage.
