Accupro 12177470 Tapered End Mill 1/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177470 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. Built from micrograin solid carbide, this tool features a 1.5 degree taper angle per side and a 1/8 inch small end diameter. The square end profile and center-cutting capability make it well-suited for plunge entry, slot milling, and contour work in ferrous and non-ferrous materials. With 3 spiral flutes in a right-hand direction and a 30-degree helix angle, the tool promotes efficient chip evacuation and smooth cutting action. The uncoated finish suits applications where coating buildup or heat sensitivity is a concern.

This tapered end mill is intended for use in CNC machining centers, vertical mills, and manual milling machines handling precision die work, mold making, cavity machining, and fine detail contouring. The 1/8 inch small diameter and 1 inch length of cut make it appropriate for narrow slots, angled walls, and draft-angle features common in tooling and fixture fabrication. Machinists and toolmakers in job shops and production environments are the primary users of this tool.

Key Features

• 1.5 degree taper per side for precise angled wall geometry
• Micrograin solid carbide construction for rigidity and edge retention
• Center-cutting design allows direct plunge entry
• 3 right-hand spiral flutes with 30-degree helix for efficient chip removal
• Square end profile suits flat-bottom slots and stepped features
• Uncoated finish suitable for non-ferrous and specialty material applications

Compatibility

Designed for use in standard 3/16 inch collet or end mill holder systems on CNC and manual milling machines requiring a tapered carbide end mill with a square end profile.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle and collet are clean and free of debris before seating the 3/16 inch shank. Confirm proper tool projection and holding torque per the collet manufacturer specification before initiating a cut. Carbide tooling is brittle and should never be used in setups with excessive overhang or workholding instability.
