Accupro 12177623 Tapered Ball End Mill 3 Flute Carbide

Product Description

The ACCUPRO 12177623 is a solid carbide tapered ball end mill designed for precision milling of contoured surfaces, mold cavities, and die work. The 3-degree taper angle per side and ball end geometry allow machinists to reach into deep pockets and cut smooth radii in a single setup. Built from micrograin carbide in a bright, uncoated finish, this tool delivers rigidity and edge retention on ferrous and non-ferrous materials. The 3-flute, right-hand spiral design balances chip evacuation with surface finish quality. A 30-degree helix angle reduces cutting forces and promotes smooth entry into the workpiece.

This end mill is suited for CNC machining centers and manual mills in tool-and-die, mold-making, and precision part manufacturing environments. The 5/32-inch small end diameter and 1-3/4-inch length of cut make it appropriate for detailed finishing passes and semi-finishing of tapered walls and blended contours. The 3/8-inch shank fits standard collet chucks and end mill holders common in production and job-shop setups. It is centercutting, allowing direct plunge entry where required.

Key Features

• 3-degree taper angle per side for draft-wall and mold-cavity milling
• Ball end geometry with 5/64-inch nose radius for smooth contour and radius cuts
• Micrograin solid carbide construction for edge retention and rigidity
• 3-flute, right-hand spiral with 30-degree helix for efficient chip removal
• Centercutting capability allows direct plunge milling
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in standard 3/8-inch collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a tapered ball end mill with a 3-degree included taper.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a clean, undamaged collet or holder and torque the retention nut to the holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to protect both the tool and the workpiece.
