Accupro 12178727 Corner Radius End Mill 1 in 7 Flute Altin

Product Description

The ACCUPRO 12178727 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and hardened materials. It features a 1 inch cutting diameter, a 0.03 inch corner radius, and 7 flutes with a right-hand spiral and right-hand cutting direction. The tool is coated with AlTiN for heat resistance and extended tool life at elevated cutting temperatures. The variable index flute spacing reduces harmonic vibration during aggressive cuts. This end mill is a single-end, centercutting tool installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for profiling, slotting, and finishing operations on ferrous alloys, hardened steels, and stainless steel. Its 2.625 inch length of cut supports deep-pocket milling without requiring extended-reach geometry. The 1 inch shank diameter fits standard ER and side-lock holders used on vertical and horizontal machining centers. Micrograin carbide substrate provides the hardness and edge retention needed for demanding material removal rates in production settings.

Key Features

• Solid micrograin carbide construction for hardness and edge retention in difficult materials
• AlTiN coating provides oxidation resistance and reduces heat transfer to the tool body
• 7-flute variable index geometry reduces chatter and improves surface finish
• 0.03 inch corner radius extends tool life at cutting edges and reduces workpiece stress concentrations
• Centercutting design allows plunge entry without a pre-drilled pilot hole
• Right-hand flute direction and right-hand cut for standard CNC spindle configurations

Compatibility

Designed for use in standard 1 inch bore end mill holders, ER collet chucks, and side-lock tool holders on CNC vertical or horizontal machining centers.

Installation Notes

This tool is installed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the tool holder to the machine builder specification listed in your setup documentation. Verify runout at the cutting diameter before beginning a production cut, as excessive runout accelerates wear on carbide end mills and can cause premature edge failure.
