Accupro 12183529 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12183529 is a solid carbide corner radius end mill designed for precision milling operations in metal and hard-material applications. Built with a 3/8 inch diameter and a 0.06 inch corner radius, it produces smooth, radiused edges that reduce stress concentrations and extend workpiece life. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and a stable cut. At 4 inches overall length with a 1 inch length of cut, this is a long-series end mill suited for reaching into deeper pockets and slots. Micrograin carbide construction provides the hardness and wear resistance required for consistent performance in demanding machining environments.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and contouring operations where a radiused corner is required. The single-end, centercutting geometry allows plunge entry as well as conventional side milling. Typical applications include die and mold work, aerospace component machining, and general precision part production. The bright uncoated finish makes it a solid choice for non-ferrous materials and applications where coating residue or heat buildup is a concern.

Key Features

• 0.06 inch corner radius reduces stress concentration and edge chipping on finished workpieces
• Micrograin solid carbide construction for superior hardness and wear resistance
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Long-series length of cut at 1 inch provides reach for deeper pocket and slot work
• Bright uncoated finish suits non-ferrous and general-purpose milling applications

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual milling machines accepting a 3/8 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the end mill. Seat the shank fully and evenly in a properly sized collet or tool holder and torque the drawbar or clamping nut to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating.
