Accupro 72046535 Corner Radius End Mill 3/16 in 6 Flute

Product Description

The ACCUPRO 72046535 is a single-end, solid carbide corner radius end mill designed for high-precision milling of high-temperature alloys and other demanding workpiece materials. With a 3/16-inch (0.1875 inch) mill diameter and 6-flute geometry featuring a variable helix and variable index configuration, this end mill reduces harmonic chatter and improves surface finish in difficult-to-machine materials. The AlTiN+ coating provides enhanced heat and oxidation resistance, extending tool life in elevated cutting temperatures. Center-cutting capability allows plunge entry, giving machinists flexibility in toolpath strategy without requiring a separate spot or plunge tool.

This end mill is suited for aerospace, power generation, and industrial machining applications where high-temp alloys such as Inconel, titanium, and similar S-group materials are commonly encountered. The 5/16-inch length of cut and 2-inch overall length make it well matched to finishing and semi-finishing passes in slotting, profiling, and contouring operations on CNC vertical and horizontal machining centers. The 0.010-inch corner radius reduces stress concentration at the cutting edge, extending tool life on hard materials.

Key Features

• Variable helix and variable index geometry reduces chatter in high-temp alloy cutting
• AlTiN+ coating delivers superior heat and oxidation resistance for elevated-temperature applications
• 6-flute design increases feed rate potential and improves surface finish
• 0.010-inch corner radius extends edge life and reduces chipping at cutting corners
• Center-cutting construction supports direct plunge entry
• Solid carbide construction provides rigidity and dimensional stability under load

Compatibility

Designed for use in CNC machining centers with a 3/16-inch collet or end mill holder accepting a 0.1875-inch shank diameter. Optimized for primary use in high-temp alloy (S-group) workpiece materials per manufacturer designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine is in a safe state before changing tooling. Use a properly sized collet or hydraulic holder sized to the 0.1875-inch shank to maintain runout concentricity. Verify tool projection and length of cut engagement match the programmed toolpath before starting a cut.
