Accupro 12177504 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177504 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper angle. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention needed for demanding cutting applications in metals, hardened steels, and engineered plastics. It features a 3-degree taper per side, a 1/8 inch small end diameter, and a 1-1/2 inch length of cut. The 3-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining a clean finish. This tool is typically installed and operated by machinist and CNC tooling professionals in job shop and production environments.

This tapered end mill is suited for CNC machining centers and manual milling machines where tapered walls, draft angles, or contoured pockets are required. The square end configuration makes it appropriate for flat-bottom slots and stepped features. The uncoated micrograin carbide construction is well suited for dry cutting or applications where coating compatibility with the workpiece material is a concern. The 5/16 inch shank diameter fits standard collet and end mill holder systems commonly found in vertical and horizontal machining setups.

Key Features

• 3-degree taper per side for accurate draft angle and tapered wall milling
• Micrograin solid carbide construction for superior hardness and edge retention
• 3-flute spiral geometry with 30-degree helix angle for efficient chip removal
• Square end profile supports flat-bottom slots and pockets
• Centercutting capable, allowing plunge entry into the workpiece
• Uncoated finish suitable for a wide range of base materials and cutting fluids

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 5/16 inch shank diameter in standard collet or end mill holder systems.

Installation Notes

This tool should be installed by a qualified machinist or CNC tooling technician familiar with end mill holder torque procedures and runout inspection. Ensure the machine spindle is fully powered down and locked before changing tooling. Verify collet size matches the 5/16 inch shank diameter before seating the tool. Do not exceed the manufacturer-recommended depth of cut for the taper geometry to avoid tool deflection or breakage.
