Accupro 12177455 Tapered End Mill 1/8 in Solid Carbide

Product Description

The ACCUPRO 12177455 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. With a 1-degree taper angle per side, a 1/8-inch small end diameter, and a 3/4-inch length of cut, this tool delivers accurate tapered profiles in ferrous and non-ferrous materials. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. Licensed machinists and CNC tooling specialists typically select this tool for die work, mold making, and precision part production where tight tapered geometry is required.

This tapered end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills running appropriate spindle speeds for solid carbide tooling. The square end geometry makes it applicable for floor work and finishing passes in tapered pockets or draft-angle features. Its 3/16-inch shank diameter fits standard ER and collet chuck toolholding systems commonly found in machine shops. The uncoated micrograin carbide construction is appropriate for aluminum, brass, plastics, and softer steels where a coated tool is not required.

Key Features

• 1-degree taper angle per side for precise draft and tapered profile milling
• Micrograin solid carbide construction for superior hardness and edge retention
• Three spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting capable, allowing direct plunge entry
• Right-hand flute direction compatible with standard spindle rotation
• Uncoated finish suitable for non-ferrous metals, plastics, and softer materials

Compatibility

Designed as a direct-fit tapered end mill for CNC and manual milling machines accepting a 3/16-inch shank diameter via collet chuck or ER toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the 3/16-inch shank firmly in a clean, properly sized collet or end mill holder before operation, and verify runout with a dial indicator before cutting. Power down and lock out the machine spindle completely before changing or setting tooling. Do not exceed the recommended depth of cut for the 3/4-inch length of cut to avoid tool deflection or breakage.
