Accupro 12177464 Tapered End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12177464 is a solid carbide tapered end mill designed for precision milling operations in metal fabrication, tool-and-die, and machining shops. It features a 3/8-inch small end diameter, a 1-degree taper angle per side, and a 1-1/4-inch length of cut. The 3-flute, right-hand spiral geometry with a 30-degree helix angle provides efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this end mill delivers the rigidity and wear resistance required for tight-tolerance work in hardened and ferrous materials. The uncoated finish suits applications where additional coating is not required or where regrinding is anticipated.

This end mill is suited for tapered pocket milling, draft-angle features, and contour work on CNC machining centers and manual mills. The square end geometry makes it appropriate for flat-bottom and corner applications. The centercutting design allows plunge entry where required. It is typically used by machinists and tool-and-die makers working on mold components, fixtures, and precision parts requiring a consistent taper along the cutting length.

Key Features

• 1-degree taper angle per side for consistent draft geometry along the cut
• Micrograin solid carbide construction for rigidity and extended tool life
• 3-flute right-hand spiral with 30-degree helix for efficient chip removal
• Centercutting capable - allows plunge milling entry
• Uncoated finish suitable for regrinding or applications not requiring a surface treatment
• Square end geometry for flat-bottom pockets and contoured features

Compatibility

Designed as an OEM-style replacement or direct-use tapered end mill for CNC machining centers and manual mills accepting a 7/16-inch round shank.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state per applicable shop safety procedures. Secure the 7/16-inch shank in a compatible collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a production cut. Tapered end mills are sensitive to lateral load - confirm toolpath and depth-of-cut parameters in CAM software before running.
