Accupro 12177505 Tapered End Mill Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177505 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. It features a 3-degree taper angle per side, a 1/8 inch small end diameter, and a 2 inch length of cut. With three right-hand spiral flutes and a 30-degree helix angle, it delivers efficient chip evacuation and consistent surface finishes in ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and wear resistance in demanding machining environments. The bright, uncoated finish makes it suitable for general-purpose cutting applications where coating buildup is a concern.

This end mill is used in CNC machining centers and manual mills where tapered walls, dovetail approaches, or draft-angle features must be cut to close tolerances. The 3/8 inch straight shank and 4 inch overall length suit it for mid-reach setups in die, mold, and precision component work. The centercutting capability allows it to plunge directly into the workpiece. It is typically run by machinists, toolmakers, and CNC operators in job shops, aerospace, and manufacturing environments.

Key Features

• 3-degree taper angle per side for precise draft and tapered wall geometry
• Micrograin solid carbide construction for rigidity and extended tool life
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge entry without pre-drilling
• Bright, uncoated finish suitable for general-purpose and non-ferrous applications
• Square end profile for flat-bottomed tapered features

Compatibility

Designed as a standard straight-shank tapered end mill compatible with ER collet chucks, end mill holders, and other 3/8 inch shank toolholding systems used on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists and CNC operators. Secure the 3/8 inch shank firmly in a properly sized collet or end mill holder, ensuring adequate engagement length to minimize runout and tool pull-out risk. Verify spindle speed and feed rate parameters match the workpiece material and depth of cut before engaging the tool. Inspect the cutting edges for chips or wear before each use, as carbide tools can fail suddenly if run in a damaged condition.
