Accupro 12177529 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177529 is a solid carbide tapered end mill designed for precision machining applications requiring controlled taper geometry. It features a 5-degree taper angle per side, a 3/16-inch small end diameter, and a 2-1/2-inch length of cut. The three-flute, right-hand spiral configuration with a 30-degree helix angle supports efficient chip evacuation and stable cutting at moderate to high feed rates. Micrograin carbide construction provides rigidity and edge retention in ferrous and non-ferrous materials. The uncoated finish makes it suitable for use in materials where coating adhesion or heat sensitivity is a concern. Machinists and CNC operators install this tool in milling machines and machining centers for tapered pocket, draft angle, and die work.

This end mill is suited for precision die and mold work, aerospace component machining, and any application requiring a consistent taper profile in a workpiece. The square end geometry supports flat-bottomed tapered slots and pockets. The 5/8-inch shank diameter provides solid tool holding in standard end mill holders and collet chucks. Its 4-5/8-inch overall length allows reach into deeper cavities without sacrificing rigidity. Centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• 5-degree taper angle per side for consistent draft and taper profile geometry
• Micrograin solid carbide construction for edge retention and rigidity
• 3-flute right-hand spiral with 30-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Uncoated finish suited for applications where bare carbide is preferred
• 5/8-inch shank compatible with standard end mill holders and collet chucks

Compatibility

Designed as a direct-mount tapered end mill for use in milling machines and CNC machining centers accepting a 5/8-inch straight shank end mill holder or collet chuck.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before seating or removing the tool from the holder. Ensure the shank is fully engaged in the collet or holder to the recommended grip depth before tightening. Inspect the cutting edges and shank for damage before each use and confirm runout with a dial indicator when tight tolerances are required.
