Accupro 12177526 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177526 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper profile. It features a 5-degree taper angle per side and a 1/8-inch small end diameter, making it well suited for die work, mold cavities, and angled wall finishing. The 3-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining a stable cut. The square end configuration delivers clean, flat-bottomed features. The uncoated micrograin carbide substrate offers a sharp cutting edge and consistent performance across a range of workpiece materials.

This end mill is used in CNC machining centers, vertical mills, and die-sink applications where tapered side walls or draft angles are required. Typical applications include mold and die finishing, cavity profiling, and tapered slot milling in ferrous and non-ferrous materials. With a 1-1/2-inch length of cut and a 4-inch overall length, it reaches deeper pockets while maintaining rigidity. It is primarily installed and operated by machinists and toolroom technicians working in precision manufacturing environments.

Key Features

• 5-degree taper angle per side for accurate draft-angle milling
• Solid micrograin carbide construction for edge sharpness and wear resistance
• 3-flute right-hand spiral design with 30-degree helix for efficient chip flow
• Square end geometry produces flat-bottomed features and clean floor finishes
• Centercutting capable, allowing plunge entry into the workpiece
• Uncoated finish maintains a consistent edge geometry for re-sharpening

Compatibility

Designed as an OEM-style solid carbide tapered end mill compatible with standard CNC and manual milling machine spindles accepting a 7/16-inch round shank.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the 7/16-inch shank in a properly sized collet or end mill holder and torque to the machine tool specification before operation. Ensure the spindle and tool holder are clean and free of chips before seating the tool. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or chipping.
