Accupro 12177435 Tapered End Mill Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177435 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. Built from micrograin solid carbide with a bright/uncoated finish, it features a 0.5 degree taper angle per side and a 3-flute, right-hand spiral geometry with a 30 degree helix angle. The square end configuration allows flat-bottom cutting, and the center-cutting capability supports direct plunge entry. With a small end diameter of 3/32 inches and a 1/8 inch shank diameter, this tool is suited for detailed work in tight geometries. Machinists and toolroom operators install this end mill in CNC machining centers and manual mills for tapered slot, draft-angle, and mold-cavity applications.

This tapered end mill is used in applications where a consistent draft angle or tapered wall profile is required, such as mold and die work, core and cavity machining, and precision part manufacturing. The 3/4 inch length of cut and 2-1/4 inch overall length make it appropriate for moderate-depth passes in ferrous and non-ferrous materials where micrograin carbide provides the necessary edge retention and rigidity.

Key Features

• 0.5 degree taper angle per side for precise draft and tapered-wall milling
• Micrograin solid carbide construction for rigidity and edge retention
• 3-flute right-hand spiral geometry with 30 degree helix angle for efficient chip evacuation
• Center-cutting design supports direct plunge entry without pre-drilling
• Square end profile enables flat-bottom cuts in slots and pockets
• Bright/uncoated finish suitable for use with or without coolant

Compatibility

Designed as a standard taper shank end mill for use in CNC machining centers, knee mills, and toolroom milling machines accepting a 1/8 inch round shank via collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully powered down and at rest before loading or unloading the tool. Secure the 1/8 inch shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates wear on small-diameter carbide tooling.
