Accupro 14981771 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14981771 is a solid carbide square end mill designed for precision milling in steel and similar ferrous workpiece materials. With a 1/16 inch (0.0625 inch) mill diameter and three flutes, this tool delivers efficient chip evacuation and a clean finish in tight-tolerance applications. The right-hand cutting and right-hand spiral flute geometry, combined with a 30-degree helix angle, promotes smooth cutting action and reduced chatter. At 2.5 inches overall length with a 3/8 inch length of cut, this is an extra-long configuration suited for reaching into deeper features without tool changes.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter, extra-long reach tooling is required. It is center-cutting, allowing plunge entry directly into the workpiece. The 1/8 inch straight shank fits standard collet chucks and end mill holders common in job shops, tool rooms, and production machining environments. Primary workpiece material is steel, making it suitable for general-purpose ferrous milling work including slots, pockets, and contour passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in steel milling
• 3-flute design balances chip evacuation and cutting edge strength at small diameters
• Center-cutting geometry allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Extra-long length type provides extended reach for deep-feature machining
• Bright/uncoated finish — ready for use as-delivered or compatible with operator-applied coatings

Compatibility

Designed as a direct-fit replacement or standard tooling selection for applications requiring a 1/8 inch straight shank, 1/16 inch diameter, three-flute square end mill in ferrous machining setups. Part of ACCUPRO Series 524.

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible collet chuck or end mill holder rated for 1/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after tightening to minimize deflection, which is especially critical at small diameters. Follow machine manufacturer torque guidelines for collet nut tightening.
