Accupro 95172635 Corner Radius End Mill 5/8 in 4 Flute Carbide

Product Description

The ACCUPRO 95172635 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard-alloy materials. It features a 5/8 inch diameter with a 0.0300 inch corner radius and four right-hand spiral flutes with a 38-degree helix angle. The cutting zone spans 3/4 inch length of cut, and the overall length is 3.5 inches. An AlCrTiN coating provides thermal resistance and wear protection at elevated cutting temperatures. The 5/8 inch Smart-Weldon shank is ground to an h6 tolerance for secure, precise tool holding. This end mill is centercutting and single-end, making it suitable for plunge entry and multi-direction cutting paths. Machinists and CNC operators in job shops, aerospace, and moldmaking environments typically run this tool.

This end mill is used in stub-length extended-reach applications where rigidity and reach must be balanced. The ultra-fine micrograin carbide grade supports high-speed finishing and semi-finishing passes on hardened steels, stainless, and similar difficult-to-machine alloys. The right-hand cutting direction and spiral flute geometry promote chip evacuation during side milling and slotting. It is suited for CNC machining centers with coolant delivered externally, as this tool does not feature through-coolant capability. Series ST designation indicates the specific geometry and shank family within the ACCUPRO product line.

Key Features

• 5/8 inch mill diameter with 0.0300 inch corner radius for controlled edge blending
• AlCrTiN coating for high-temperature wear resistance in ferrous and hard-alloy cuts
• Ultra-fine micrograin solid carbide substrate for edge sharpness and toughness
• 38-degree helix angle promotes smooth cutting action and efficient chip flow
• Smart-Weldon shank ground to h6 tolerance for accurate, repeatable tool holding
• Centercutting design permits direct plunge entry without pre-drilling
• Corner radius tolerance held to +0.00000 to -0.00100 inch for precision profiling

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 5/8 inch Smart-Weldon shank. Verify spindle taper and collet or chuck compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the Smart-Weldon shank fully into the tool holder and torque the retention mechanism per the tool holder manufacturer specifications. Inspect the corner radius and cutting edges for chips or damage before each use.
