Accupro 12177478 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177478 is a solid carbide tapered end mill designed for precision milling operations requiring angled wall profiles and tight tolerances. It features a 2-degree taper per side with a small end diameter of 1/16 inches and a 3/16-inch shank diameter. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The square end profile and centercutting capability allow for both plunge and peripheral milling. Machined from micrograin solid carbide, this tool delivers rigidity and wear resistance in demanding cutting conditions. It is supplied uncoated and ready for immediate use.

This tapered end mill is suited for use on CNC machining centers, vertical mills, and manual knee mills where tapered slots, draft angles, or relief cuts are required. With a 1-inch length of cut and a 2-1/2-inch overall length, it fits standard toolholding systems with 3/16-inch collets or chucks. It is commonly used by machinists and toolmakers in mold-making, die work, and precision part manufacturing where consistent taper angles are critical.

Key Features

• 2-degree taper per side produces accurate draft angles in a single pass
• Micrograin solid carbide construction provides rigidity and extended tool life
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Square end with centercutting capability allows plunge entry and peripheral cuts
• Uncoated finish suitable for use with or without cutting fluid in a range of workpiece materials
• 1-inch length of cut with 2-1/2-inch overall length fits compact toolholding setups

Compatibility

Designed as an OEM-style replacement or direct-application tapered end mill for machining setups requiring a 3/16-inch shank and 2-degree taper per side geometry.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting, ensure the spindle is fully stopped and the machine is powered down or placed in an e-stop condition. Seat the 3/16-inch shank fully and securely in a matching collet or toolholder to prevent runout. Verify taper angle setup against part drawing requirements before cutting to avoid scrap.
