Accupro 315724 Corner Radius End Mill 1 in Solid Carbide Zrn

Product Description

The ACCUPRO 315724 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1 inch cutting diameter, a 1.25 inch length of cut, and a 6 inch overall length with extended reach capability. The 3-flute, right-hand spiral geometry paired with a ZrN (zirconium nitride) coating delivers improved wear resistance and surface finish in ferrous and non-ferrous materials. A 37-degree variable-geometry helix promotes chip evacuation and reduces chatter. This tool is centercutting, allowing plunge entry into the workpiece. Machinists and CNC programmers working in job shop, aerospace, mold, and die environments will find this end mill suited for deep-reach finishing and semi-finishing operations.

This end mill is intended for use in CNC machining centers and manual mills where extended reach is required to access deep cavities, pockets, or contoured surfaces. The 3-3/8 inch reach length and 0.95 inch neck diameter allow the cutter to clear workpiece walls without interference. The corner radius end type, with a 0.060 inch radius, reduces stress concentration at the cutting edge and produces a controlled blend radius at the floor-to-wall transition. Typical applications include mold cavities, die blocks, and structural aerospace components machined from alloy steels, stainless steels, and hardened materials.

Key Features

• 1 inch cutting diameter with 0.060 inch corner radius for controlled floor-to-wall blending
• Solid micrograin carbide construction for rigidity and edge retention in hard materials
• ZrN coating improves surface hardness and lubricity for extended tool life
• 3-flute right-hand spiral geometry with 37-degree helix for efficient chip evacuation
• Extended reach design with 3.375 inch reach length and 0.95 inch neck diameter
• Centercutting capability allows direct plunge entry without pre-drilling

Compatibility

Designed for use in CNC machining centers and manual milling machines with standard 1 inch toolholders or collet systems accepting a 1 inch shank diameter. Suitable for milling ferrous and non-ferrous metals where extended reach and corner radius geometry are required.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the 1 inch straight shank in a precision collet, hydraulic chuck, or shrink-fit holder to minimize runout; excessive runout accelerates edge wear and reduces surface finish quality. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Follow the toolholder manufacturer's torque specifications for set screws or clamping mechanisms, and verify tool projection length against programmed reach values before running the first cycle.
