Accupro 12181305 Corner Radius End Mill 3/16 in 2 Flute Altin

Product Description

The ACCUPRO 12181305 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It carries a 0.01 inch corner radius that reduces stress concentrations at the cutting edge, extending tool life in demanding applications. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating adds thermal and abrasion resistance, making this tool well-suited for dry or high-speed cutting environments. At 0.06 pounds, it is a compact, single-end tool intended for use in CNC machining centers and manual mills operated by machinists and tooling professionals.

This end mill fits standard milling setups where a small-diameter, corner-radius profile is required. The 3/16 inch diameter and 5/8 inch length of cut make it appropriate for slotting, profiling, and contouring in confined workpiece features. The centercutting design allows plunge entry directly into the material. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle configurations. This tool is a single-end design, meaning it is not reversible and should be replaced when the cutting end is worn.

Key Features

• AlTiN coating provides high thermal resistance for dry and high-speed cutting
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting force
• 0.01 inch corner radius reduces edge chipping and stress at the tool tip
• Centercutting geometry allows direct plunge entry into workpiece material
• Micrograin solid carbide substrate delivers hardness and dimensional stability
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Use a properly sized collet or end mill holder to secure the 3/16 inch shank, and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the coating and substrate material.
