Accupro 12177480 Tapered End Mill Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177480 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. Built from micrograin carbide, it delivers consistent edge integrity and wear resistance across a range of workpiece materials. The square end geometry provides clean, flat-bottom cuts, while the 2-degree taper per side creates draft angles commonly needed in die, mold, and contour milling work. With a 3-flute spiral configuration and a 30-degree helix angle, this tool balances chip evacuation with surface finish quality. It is intended for use in CNC machining centers and manual mills by machinists and toolroom professionals.

This end mill suits applications in die and mold making, aerospace component machining, and general precision metalworking where tapered wall features are required. The small end diameter of 5/64 inches and a 1-inch length of cut allow it to reach into tight pockets and contoured surfaces. The 3/16-inch shank fits standard collet and toolholder systems common to vertical machining centers. Its centercutting capability permits plunge entry without a pre-drilled pilot hole, adding setup flexibility for complex workpiece geometries.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 2-degree taper per side for precise draft angle milling in die and mold applications
• Square end geometry produces flat-bottom cuts and clean shoulder profiles
• 3-flute spiral design with 30-degree helix angle balances chip clearance and finish quality
• Centercutting design allows direct plunge entry into workpiece material
• Uncoated finish suitable for use with cutting fluids on a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct toolroom addition for CNC machining centers and manual mills accepting a 3/16-inch shank diameter via standard ER collet or end mill holder systems.

Installation Notes

Installation should be performed by a qualified machinist following established shop safety procedures. Ensure the machine spindle is fully powered down and locked out before mounting or removing the tool from its holder. Seat the shank fully into the collet or toolholder to the recommended grip depth before tightening to avoid runout and premature tool wear. Verify taper angle programming in the CAM or CNC control matches the 2-degree-per-side geometry before cutting.
