Accupro 14796240 Corner Radius End Mill 1/16 in 3 Flute Altin

Product Description

The ACCUPRO 14796240 is a miniature solid carbide corner radius end mill designed for precision milling in tight geometries and small-feature applications. With a 1/16 inch (0.0625 inch) mill diameter and a 0.0100 inch corner radius, this tool delivers controlled edge blending and reduced stress concentration at corner transitions. The 3-flute, right-hand spiral configuration with a 30-degree helix promotes efficient chip evacuation in ferrous and non-ferrous materials. The AlTiN coating enhances heat resistance and extends tool life in high-speed dry or semi-dry cutting environments. This end mill is single-end and centercutting, suitable for plunge entry. It is installed and operated by machinists and CNC programmers working with precision milling equipment.

This tool is suited for miniature and micro-milling operations in production machining, tool and die, mold making, and precision part manufacturing environments. The extended reach design, with a 0.5000 inch reach length, allows access to recessed features and deep-pocket sidewalls without interference from the shank. The 1/8 inch shank diameter fits standard miniature collets on CNC machining centers and high-speed spindles. Applications include profiling, slotting, and contouring in hardened steels, stainless, titanium, and other demanding workpiece materials where AlTiN coating performance is advantageous.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in demanding cuts
• AlTiN coating provides elevated temperature resistance for dry and high-speed machining
• 0.0100 inch corner radius reduces edge chipping and stress at workpiece corners
• Extended reach with 0.5000 inch reach length for access to recessed and deep-pocket features
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute spiral with 30-degree helix for effective chip removal

Compatibility

Designed for use with standard 1/8 inch miniature collet systems on CNC machining centers and high-speed spindles. Fits any toolholder accepting a 1/8 inch straight shank with a shank diameter tolerance of -0.0001 to -0.0003 inch.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully stopped and the control in a safe state per shop lockout-tagout procedures. Seat the 1/8 inch shank fully and evenly in the collet to the recommended gauge length before tightening to avoid runout. Verify tool runout with a dial indicator before production use, as excessive runout on miniature-diameter end mills accelerates breakage. Follow machine manufacturer torque specifications for collet nut tightening.
