Accupro 12177434 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177434 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. Built from micrograin carbide, it delivers the hardness and edge retention needed for tight-tolerance work in ferrous and non-ferrous materials. The square end geometry produces flat-bottomed features, while the 0.5-degree taper per side creates precise draft angles in molds, dies, and similar tooling applications. With 3 spiral flutes and a 30-degree helix angle, it promotes efficient chip evacuation and smooth cutting action. The uncoated finish makes it suitable for use with cutting fluids where coating adhesion is not required.

This end mill is used in CNC machining centers and manual mills for applications such as mold making, die work, and engraving where a tapered wall profile is needed. The small end diameter of 0.0625 inches (1/16 inch) and 1-inch length of cut allow access to narrow cavities and deep features. It is installed and operated by machinists and tool-and-die professionals working in precision job shops and production environments.

Key Features

• 0.5-degree taper angle per side for controlled draft in mold and die work
• Micrograin solid carbide construction for hardness and edge retention
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Square end geometry produces flat-bottomed cuts
• Centercutting design allows plunge entry
• Uncoated finish compatible with wet cutting and oil-based coolants

Compatibility

Designed as a standard-shank tapered end mill for use in CNC machining centers and manual milling machines accepting a 1/8-inch collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer specifications for runout and clamping torque. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Confirm spindle speed and feed rate are set appropriately for the workpiece material and cutting depth before engaging the cut. Never exceed the rated length of cut when side milling.
