Accupro 12177437 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177437 is a solid carbide tapered end mill designed for precision milling operations where a controlled taper profile is required. It features a 0.5-degree taper angle per side and a small end diameter of 1/8 inch, making it well suited for tight-tolerance work in dies, molds, and contoured surfaces. With 3 spiral flutes, a 30-degree helix angle, and a micrograin carbide substrate, this tool delivers clean cuts and resists wear in ferrous and non-ferrous materials. The square end geometry supports flat-bottom profiling and slotting. It is centercutting, allowing plunge entry. Installation and use are performed by machinists operating CNC machining centers or manual mills.

This tapered end mill is used in tool-and-die shops, mold making, aerospace component machining, and general precision machining environments. The 1/2-inch length of cut and 2-inch overall length make it practical for shallow-to-moderate depth passes in confined features such as draft-angle walls and tapered pockets. The uncoated finish makes it a straightforward choice for shops that re-coat tooling in-house or work with softer workpiece materials where coating is not critical. Right-hand flute direction and right-hand cut are standard for conventional CNC spindle rotation.

Key Features

• 0.5-degree taper angle per side for consistent draft-angle profiling
• Micrograin solid carbide construction for rigidity and edge retention
• 3 spiral flutes with 30-degree helix angle for smooth chip evacuation
• Centercutting design allows direct plunge entry
• Square end geometry supports flat-bottom slots and profiles
• Uncoated finish compatible with in-house coating workflows or non-ferrous applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide tapered end mill for CNC machining centers and manual mills accepting a 3/16-inch straight shank.

Installation Notes

Install and secure the shank in a collet or end mill holder rated for the 3/16-inch shank diameter before spindle engagement. Ensure the machine spindle is fully stopped and locked out before tool changes. Verify runout with a dial indicator after seating to confirm concentricity before cutting. Follow shop-standard feeds and speeds for solid carbide tooling based on workpiece material.
