Accupro 12177546 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177546 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. It features a 10-degree taper angle per side and a small end diameter of 1/8 inch, making it well suited for narrow slot work, die work, and contour milling in hard or abrasive materials. The 3-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention needed in demanding cutting environments. The uncoated finish keeps the tool ready for applications where coating is unnecessary or where regrinding is anticipated.

This tapered end mill is used in machining applications where draft angles, mold cavities, or tapered wall profiles are required. It is appropriate for use on CNC machining centers and manual mills across tool-and-die, mold-making, and general precision machining environments. The center-cutting design allows plunge entry, adding flexibility to the range of operations it can handle. The 3/4-inch length of cut and 2-3/4-inch overall length suit it to moderate-depth tapered features in ferrous and non-ferrous materials.

Key Features

• 10-degree taper angle per side for precise draft and taper wall geometry
• Micrograin solid carbide construction for hardness and edge retention
• 3-flute right-hand spiral with 30-degree helix for efficient chip removal
• Center-cutting capable - supports plunge entry operations
• Uncoated finish suitable for regrinding or applications not requiring a coating
• Square end profile for flat-bottomed tapered features

Compatibility

Designed as a standard-shank tapered end mill with a 7/16-inch shank diameter, compatible with collet chucks and end mill holders sized to accept 7/16-inch round shanks on CNC and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and in a locked-out state. Ensure the collet or tool holder is clean and free of debris before seating the shank to the full depth of engagement. Verify runout with a dial indicator before beginning a cut, as excess runout will accelerate wear on a 3-flute carbide tool. Follow the machine manufacturer and tooling supplier recommendations for speeds and feeds based on material and depth of cut.
