Accupro 12177514 Tapered End Mill 3 Flutes Solid Carbide

Product Description

The ACCUPRO 12177514 is a solid carbide tapered end mill designed for precision milling applications requiring controlled taper geometry and a clean square end finish. It features a 3-degree taper angle per side, a 1/4-inch small end diameter, and a 2-1/4-inch length of cut. Built from micrograin solid carbide, this tool delivers the hardness and edge retention needed for tight-tolerance work in ferrous and non-ferrous materials. The uncoated finish makes it well suited for applications where coating interaction with the workpiece material is a concern. Three right-hand spiral flutes with a 30-degree helix angle support efficient chip evacuation during cutting.

This tapered end mill is used in CNC machining centers and manual milling operations where tapered wall profiles, draft angles, or die and mold cavities are required. The centercutting capability allows plunge entry into the workpiece. The 1/2-inch shank diameter fits standard ER and end mill holder collet systems. Typical users include machinists, toolmakers, and CNC operators working in job shops, mold shops, and production machining environments.

Key Features

• 3-degree taper angle per side for consistent draft geometry
• Micrograin solid carbide construction for edge hardness and wear resistance
• Centercutting design allows direct plunge entry
• Three right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Uncoated finish suitable for applications where bare carbide is preferred
• Square end profile produces flat-bottomed features and sharp corner transitions

Compatibility

Designed for use in standard 1/2-inch end mill holders, collet chucks, and ER collet systems on CNC machining centers and manual knee mills. Confirm holder runout specifications before use to protect edge geometry on this solid carbide tool.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Seat the shank fully into the holder to the recommended gauge line and torque the retention screw or collet nut to the holder specification. Inspect the tool edge under magnification before mounting to verify no chipping is present from shipping or handling.
