Accupro 12177528 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177528 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper profile. With a 5-degree taper angle per side and a 3/16-inch small end diameter, this tool produces accurate tapered walls, slots, and contours in a single pass. The 3-flute, right-hand spiral configuration with a 30-degree helix angle provides efficient chip evacuation and smooth surface finishes. Built from micrograin solid carbide, it delivers the rigidity and wear resistance needed for demanding cutting conditions. This tool is used by machinists and CNC operators in job shops, tool rooms, and production environments.

This tapered end mill is suited for milling tapered pockets, mold cavities, die work, and angled wall features in ferrous and non-ferrous materials. The 1-1/4-inch length of cut accommodates moderate-depth passes, while the 4-inch overall length provides clearance in tighter workholding setups. The uncoated finish makes it appropriate for applications where coating is not required or where re-sharpening is anticipated. The 7/16-inch shank fits standard collet and end mill holder tooling commonly found on vertical machining centers and CNC mills.

Key Features

• 5-degree taper angle per side for precise tapered wall geometry
• Micrograin solid carbide construction for rigidity and extended tool life
• 3-flute right-hand spiral with 30-degree helix for efficient chip evacuation
• Center-cutting capable, allowing plunge entry into the workpiece
• Uncoated finish suitable for regrinding and use across a range of materials
• 7/16-inch shank diameter compatible with standard collet toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit tapered end mill for use in standard 7/16-inch collet chucks and end mill holders on vertical machining centers and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the 7/16-inch shank in a matched collet or end mill holder and torque the drawbar or retention mechanism according to the machine manufacturer's specifications. Confirm runout with a dial indicator before beginning the cut. Inspect the cutting edges for chips or wear before each use, and handle carbide tooling with care to avoid edge damage.
