Accupro 12177458 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177458 is a solid carbide tapered end mill designed for precision milling in metal, composites, and hardened materials. It features a 1-degree taper angle per side and a 3/16-inch small end diameter, making it well suited for draft-angle milling, die and mold work, and tapered slot cutting. With three spiral flutes and a 30-degree helix angle, the tool delivers efficient chip evacuation and stable cutting performance. The micrograin carbide substrate provides edge retention in demanding applications. Overall length is 3 inches with a 1/4-inch shank diameter and a 1-1/4-inch length of cut. This tool is installed and operated by machinists and tool-and-die professionals.

This tapered end mill is used in CNC machining centers and manual milling machines for applications requiring a precise taper angle, including mold cavities, die work, and part features with drafted walls. The square end profile allows flat-bottom cuts at the tip. The bright/uncoated finish makes it a general-purpose option compatible with a range of cutting fluids and dry-cutting setups in ferrous and non-ferrous materials.

Key Features

• 1-degree taper angle per side for precise draft and tapered wall profiles
• Micrograin solid carbide construction for improved wear resistance and edge retention
• Three spiral flutes with 30-degree helix angle for efficient chip removal
• Square end geometry enables flat-bottom cutting at the tip
• Centercutting capable, allowing plunge entry into the workpiece
• Bright/uncoated finish for versatility across materials and cutting conditions

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC milling machines and manual mills accepting a 1/4-inch round shank end mill.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet or end mill holder rated for the 1/4-inch shank diameter. Confirm runout and tool projection before cutting to maintain taper accuracy. Follow machine manufacturer guidelines for feed rate, spindle speed, and depth of cut for carbide end mills. Inspect the cutting edges for chipping or wear before each use.
