Accupro 12177506 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177506 is a solid carbide tapered end mill designed for precision milling of angled surfaces, draft features, and tapered slots. Built from micrograin carbide, it offers rigidity and wear resistance suited to ferrous and non-ferrous machining. The cutter features a 5/32-inch small end diameter, a 1-3/4-inch length of cut, and a 3-degree taper angle per side. Three spiral flutes in a right-hand direction provide efficient chip evacuation and a smooth finish. The square end geometry allows full-depth peripheral and slot cutting in a single setup. This tool is installed by machinists and tool-and-die professionals in CNC milling operations.

This tapered end mill is suited for mold and die work, aerospace components, and general machining where tapered wall geometry is required. The 3/8-inch straight shank fits standard ER collet chucks and end mill holders. With a 30-degree helix angle and centercutting capability, it handles plunge entry as well as full-profile side milling. The 3-1/2-inch overall length provides reach into deeper pockets and cavities without excessive tool overhang.

Key Features

• Micrograin solid carbide construction for extended tool life in demanding cuts
• 3-degree taper angle per side for accurate draft and tapered wall profiles
• Centercutting geometry allows direct plunge entry without pre-drilling
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Right-hand flute direction compatible with standard CNC spindle rotation
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as a direct-fit replacement for standard 3/8-inch shank end mill holders and ER collet systems used in CNC vertical and horizontal milling applications.

Installation Notes

Installation is performed by qualified machinists. Secure the 3/8-inch shank in a clean, properly torqued collet chuck or end mill holder before spindle operation. Inspect the shank and collet bore for debris or wear before seating the tool. Follow machine tool manufacturer guidelines for runout tolerance and maximum spindle speed for the selected tool diameter and overhang length.
