Accupro 317309 Corner Radius End Mill 1in 10 Flute Carbide

Product Description

The ACCUPRO 317309 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. It features a 1 inch cutting diameter, a 0.0300 inch corner radius, and 10 flutes for improved chip evacuation and surface finish. The AlCrTiN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other tough materials. With a 3.25 inch length of cut and a 6 inch overall length, this end mill is suited for deep-cavity milling and profile work where reach and rigidity both matter. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction.

This end mill is used in CNC machining centers for die and mold work, aerospace component finishing, and precision part production. The micrograin carbide substrate and 40 degree helix angle make it effective in high-speed finishing passes and semi-finishing operations. The straight cylindrical shank with a 1 inch diameter provides secure clamping in ER collet chucks, hydraulic holders, or Weldon-style toolholders. It belongs to the ACCUPRO HS series, which targets extended-reach and high-surface-finish applications in production shops.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlCrTiN coating for thermal stability and extended tool life in hard materials
• 10-flute geometry improves surface finish and material removal rate
• 0.0300 inch corner radius reduces stress concentration at cutting edges
• 40 degree helix angle supports smooth chip flow and reduced cutting forces
• Centercutting design allows plunge entry directly into workpiece material

Compatibility

Designed as an OEM-style replacement or direct upgrade for solid carbide corner radius end mills in the HS series. Suitable for use in CNC machining centers accepting a 1 inch straight cylindrical shank with standard collet or toolholder clamping.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool change procedure follows the machine manufacturer guidelines before mounting or removing the end mill. Verify runout at the toolholder before cutting to protect both the tool and the workpiece. Consult the shop's speeds-and-feeds reference for AlCrTiN-coated carbide at the specific material hardness being machined.
