Accupro 12177553 Tapered Ball End Mill 3 Flute Carbide

Product Description

The ACCUPRO 12177553 is a solid carbide tapered ball end mill designed for precision milling operations requiring a controlled taper profile and a spherical cutting tip. With a 0.5-degree taper angle per side and a 3/32-inch small end diameter, this tool produces accurate tapered walls and contoured surfaces in a single pass. The 3-flute, right-hand spiral geometry with a 30-degree helix angle supports efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide and finished bright/uncoated, the 12177553 is suited for machinists and toolmakers working in die, mold, and precision component applications.

This tapered ball end mill is intended for use in CNC machining centers and manual mills where tight-tolerance taper profiles and 3D contour work are required. The 1/8-inch shank diameter makes it compatible with standard collet systems used in small-bore precision setups. With a 3/4-inch length of cut and a 2-1/4-inch overall length, it reaches into moderate-depth cavities while maintaining rigidity. The centercutting capability allows plunge entry, adding flexibility to toolpath strategies in die and mold work as well as precision part finishing.

Key Features

• 0.5-degree taper angle per side for controlled wall draft and tapered profile milling
• Ball end geometry with a 3/64-inch nose radius enables smooth 3D contouring and blending
• 3-flute right-hand spiral with 30-degree helix angle promotes chip evacuation and surface finish quality
• Micrograin solid carbide construction delivers hardness and wear resistance for demanding cuts
• Centercutting design permits direct plunge entry without a pre-drilled start hole
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose machining

Compatibility

Designed for use with standard 1/8-inch collet systems on CNC machining centers and precision manual mills. No specific compatible model numbers were provided by the manufacturer for this part.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the collet. Seat the shank fully into the collet to the recommended grip depth and torque the collet nut according to the collet manufacturer specification. Verify runout with a dial indicator before cutting to protect both the tool and the workpiece.
