Accupro 12177515 Tapered End Mill 3 Flutes Solid Carbide

Product Description

The ACCUPRO 12177515 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper angle. Built with a 3-degree taper per side and a 3/8-inch small end diameter, this tool is suited for profiling, slotting, and finishing passes where consistent taper geometry is critical. The micrograin carbide construction provides edge retention and rigidity in ferrous and non-ferrous materials. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The square end configuration supports clean floor finishing. Machinists and tool-and-die professionals rely on this geometry for mold work, die work, and contoured surface milling.

This end mill is used in CNC machining centers and manual milling setups where tapered wall profiles are required. Common applications include mold cavity finishing, draft angle milling, and engraving operations in tool steels, aluminum alloys, and similar materials. The 1/2-inch shank diameter seats securely in standard end mill holders and collet chucks. The 1-1/4-inch length of cut provides adequate reach for moderate-depth tapered profiles without sacrificing rigidity. The right-hand flute direction pairs with conventional right-hand spindle rotation.

Key Features

• 3-degree taper per side for precise draft angle and tapered wall milling
• Micrograin solid carbide construction for superior hardness and edge retention
• Three spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting capability allows plunge entry without pre-drilling
• 1/2-inch shank diameter compatible with standard end mill holders and collet chucks
• Uncoated finish suitable for use with or without cutting fluid in a wide range of materials

Compatibility

Designed as an OEM-style replacement or standard tooling solution for CNC machining centers and manual mills equipped with 1/2-inch end mill holders or collet chucks accepting right-hand cutting tools.

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 to the full recommended engagement depth in the holder to prevent pullout during cutting. Verify runout with a dial indicator after installation before initiating any cutting operation.
