Accupro 12177448 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177448 is a solid carbide tapered end mill designed for precision milling of contoured surfaces, tapered slots, and draft-angle features in metal, composite, and hard-material workpieces. Built from micrograin carbide, the tool holds a sharp edge longer than standard carbide grades and supports tighter tolerances in finish passes. The 1-degree taper per side produces a consistent draft angle, while the 3-flute spiral geometry with a 30-degree helix balances chip evacuation with surface finish. The square end configuration allows flat-bottom cuts. This tool is installed and operated by machinists and tool-and-die professionals using CNC machining centers and manual mills.

This tapered end mill is suited for die and mold work, engraving, and finish milling of angled walls in both prototype and production environments. The small end diameter of 1/16 inch allows access to narrow features and fine detail work where larger tools cannot reach. The 1/2-inch length of cut provides adequate flute engagement for shallow-to-moderate depth passes. The 1/8-inch shank fits standard collets and end mill holders common in CNC and manual setups. Applications include ferrous and non-ferrous metals, graphite electrodes, and engineering plastics.

Key Features

• Micrograin solid carbide construction for extended tool life and edge retention
• 1-degree taper per side for accurate draft-angle and contour milling
• 3-flute right-hand spiral with 30-degree helix balances chip flow and finish quality
• Center-cutting capable - allows plunge entry without a pre-drilled pilot hole
• Square end geometry for flat-bottom slot and pocket floors
• Uncoated finish suited for applications where coating compatibility or regrinding is a consideration

Compatibility

Designed as an OEM-style solid carbide tapered end mill for use in standard 1/8-inch collet chucks, end mill holders, and ER-series collets on CNC machining centers and manual vertical mills.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Seat the 1/8-inch shank fully into the collet or end mill holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut. Carbide is brittle - avoid side impacts during handling and storage.
