Accupro 12177449 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177449 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper angle. Built from micrograin solid carbide, this tool delivers a 1-degree taper per side with a small end diameter of 1/16 inch and a 1/8-inch shank diameter. The three-flute, right-hand spiral geometry with a 30-degree helix angle supports efficient chip evacuation while maintaining a clean, square end profile. The uncoated finish makes it well-suited for applications where close tolerances and sharp cutting edges are the priority. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills for tapered slot work, mold cavities, and detailed contouring.

This tapered end mill is used in precision machining environments including mold and die work, aerospace component manufacturing, and general metalworking where a controlled taper profile is required. The 1-inch length of cut accommodates moderate-depth passes, while the 2-1/4-inch overall length provides adequate reach for most standard fixturing setups. The centercutting capability allows direct plunge entry, giving machinists flexibility in toolpath programming without requiring a pre-drilled pilot hole.

Key Features

• 1-degree taper per side for precise tapered slot and cavity milling
• Micrograin solid carbide construction for rigidity and extended tool life
• Three-flute right-hand spiral design promotes efficient chip removal
• 30-degree helix angle balances cutting forces and surface finish quality
• Centercutting geometry allows direct plunge entry
• Uncoated finish maintains sharp edge geometry for close-tolerance work

Compatibility

Designed as a standard tapered end mill with a 1/8-inch shank diameter, compatible with collets and tool holders sized for 1/8-inch round shanks on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Use a properly sized collet or end mill holder torqued to the manufacturer specification for the holder type in use. Verify runout with a dial indicator before beginning any cut, particularly given the small shank diameter and tapered geometry of this tool.
