Accupro 12177442 Tapered End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177442 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper angle. Built with a 0.5 degree taper per side, this tool produces accurate draft angles and tapered walls in mold, die, and precision machining applications. The square end geometry delivers clean floor cuts, while the 3-flute spiral design balances chip evacuation with cutting edge strength. Manufactured from micrograin solid carbide, the 12177442 offers the rigidity and wear resistance demanded in production environments. The bright, uncoated finish is well suited for aluminum, plastics, and non-ferrous materials where coating buildup is a concern.

This tapered end mill is used in CNC machining centers for mold and die work, aerospace components, and any application requiring precise tapered slot or wall geometry. The 1/4 inch small end diameter and 3/4 inch length of cut make it appropriate for fine detail work in confined cavities. The 5/16 inch shank fits standard collet toolholders. Machinists and tool-and-die professionals working in job shops or production facilities will find this tool well suited to tight-tolerance tapered feature work.

Key Features

• 0.5 degree taper angle per side for controlled draft and tapered wall milling
• Micrograin solid carbide construction for rigidity and extended tool life
• 3-flute spiral geometry with right-hand flute direction for efficient chip removal
• Square end profile enables clean, flat floor cuts
• 30 degree helix angle balances cutting forces across the flute length
• Centercutting capable, allowing plunge entry into the workpiece
• Bright uncoated finish performs well in non-ferrous and plastic materials

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet toolholders accepting a 5/16 inch shank diameter. Suitable for mold and die work, precision cavity milling, and tapered feature machining in non-ferrous metals, aluminum, and plastics.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before loading the end mill into the collet or toolholder. Verify shank seating depth and runout with a dial indicator before cutting. Follow the machine tool manufacturer guidelines for speeds and feeds appropriate to the workpiece material and tool diameter.
