Accupro 12177544 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177544 is a solid carbide tapered end mill engineered for precision milling applications where draft angles and tapered wall profiles are required. Built from micrograin carbide, it delivers high rigidity and wear resistance in demanding cutting conditions. The tool features a 7-degree taper angle per side, a 1/2-inch small end diameter, and a 3-flute spiral configuration with a 30-degree helix angle. The square end geometry produces clean, flat-bottomed cuts. This end mill is installed and used by machinists and tool-and-die professionals working in CNC milling environments.

This tapered end mill is suited for mold-making, die work, and aerospace or general machining applications where tapered sidewalls or draft angles must be accurately cut. Its center-cutting capability allows it to plunge directly into material. The right-hand flute direction and spiral geometry promote efficient chip evacuation during profiling passes. It is appropriate for use in a range of ferrous and non-ferrous materials when used with appropriate feeds and speeds for uncoated solid carbide tooling.

Key Features

• 7-degree taper angle per side for precise draft-angle and tapered-wall milling
• Micrograin solid carbide construction for rigidity and extended tool life
• 3-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Center-cutting capable - supports direct plunge entry
• Right-hand cut, uncoated finish suitable for a wide range of base materials
• Square end geometry for flat-bottomed cut profiles

Compatibility

Designed as an OEM-style replacement or direct-use tapered end mill compatible with standard CNC milling machine spindles accepting a 7/8-inch shank diameter.

Installation Notes

Installation and tool changes must be performed by qualified machinists with the machine powered off and spindle fully stopped. Ensure the tool holder collet or end mill adapter is rated for the 7/8-inch shank diameter before securing the tool. Follow machine manufacturer torque specifications for drawbar and collet tightening. Verify runout with a dial indicator after tool installation and before beginning a cutting operation.
