Accupro 12177484 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177484 is a solid carbide tapered end mill designed for precision milling operations where controlled taper geometry is required. It features a 2-degree taper angle per side, a 1/8-inch small end diameter, and a 1-inch length of cut, making it well suited for profiling, slotting, and contouring in tight or angled workspaces. The 30-degree helix angle and right-hand spiral flute configuration promote smooth chip evacuation and stable cutting action. Micrograin carbide construction delivers hardness and edge retention in demanding cutting conditions. This tool is installed and operated by machinists and tooling technicians working on CNC or manual milling machines.

This tapered end mill is used in metalworking and precision machining environments where angled walls, mold cavities, or draft features require consistent taper geometry. The square end profile allows for flat-bottom cutting in addition to tapered side milling. The centercutting capability allows plunge entry into the workpiece without a pilot hole. Typical applications include die and mold work, aerospace component machining, and general-purpose production milling on ferrous and non-ferrous materials.

Key Features

• 2-degree taper angle per side for controlled draft geometry on profiled walls
• Micrograin solid carbide construction for edge retention and rigidity
• 3-flute, right-hand spiral design with 30-degree helix for efficient chip evacuation
• Centercutting capable — supports direct plunge entry without pre-drilling
• Uncoated finish suited for use with cutting fluids on a range of materials
• Square end profile enables flat-bottom features alongside tapered side walls

Compatibility

Designed as a standard-shank tapered end mill with a 1/4-inch shank diameter, compatible with any ER or straight-bore collet chuck or end mill holder accepting a 1/4-inch shank on CNC machining centers or manual milling machines.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or holder and torque the retention mechanism to the toolholder specification before running. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail suddenly if edge damage is present.
