Accupro 12177453 Tapered End Mill 3 Flutes Solid Carbide

Product Description

The ACCUPRO 12177453 is a solid carbide tapered end mill designed for precision milling operations requiring angled wall profiles and tight tolerances. Built from micrograin carbide stock, this tool features a square end geometry with a 1-degree taper per side, producing clean, accurate tapered features in a single pass. The 3-flute, right-hand spiral configuration at a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a small end diameter of 3/32 inches and a 1-1/4 inch length of cut, it handles detailed work in slots, pockets, and contoured surfaces across a range of machinable materials.

This tapered end mill is suited for CNC machining centers and manual milling machines used in toolmaking, moldmaking, die work, and precision part production. The 3/16 inch shank diameter fits standard collets and end mill holders. The bright, uncoated finish makes it well-matched for non-ferrous metals, plastics, and other materials where coating adhesion or heat buildup is not the primary concern. It is installed and operated by machinists and CNC programmers working in job shops, production facilities, and tool and die environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• 1-degree taper per side for accurate angled wall geometry
• 3-flute right-hand spiral with 30-degree helix for efficient chip evacuation
• Square end geometry for flat-bottom cuts and detailed floor finishing
• Centercutting design allows plunge entry into workpiece
• Bright, uncoated finish suitable for non-ferrous and plastic applications

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 3/16 inch shank diameter, compatible with CNC machining centers and manual mills configured for solid carbide tooling.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the collet or tool holder is clean and the shank is fully seated before tightening to the manufacturer-specified clamping torque for the holder type in use. Verify runout with a dial indicator after installation to protect tool life and part accuracy.
