Accupro 12177473 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177473 is a solid carbide tapered end mill designed for precision milling operations in metal cutting and machining applications. It features a 1.5-degree taper per side, a 3/16-inch small end diameter, and a 2-1/4-inch length of cut, making it well suited for tapered slot milling, die work, and angled wall profiling. The 30-degree helix angle and right-hand spiral fluting promote smooth chip evacuation and efficient cutting. With a micrograin carbide grade and an uncoated finish, this tool delivers consistent edge integrity in demanding cutting environments. Licensed machinists and CNC operators are the primary installers of this tooling.

This end mill is applied in CNC machining centers and manual milling setups where tapered features, angled walls, or draft angles must be accurately cut. It is commonly used in mold and die work, aerospace component machining, and precision job-shop operations. The square end geometry supports both plunge and peripheral milling. Its 5/16-inch shank diameter fits standard collets and end mill holders used across a wide range of machining platforms. The centercutting design allows direct plunge entry without a pre-drilled pilot hole.

Key Features

• 1.5-degree taper per side for accurate tapered slot and draft-angle milling
• Solid micrograin carbide construction for rigidity and long edge life
• 3 right-hand spiral flutes with a 30-degree helix angle for efficient chip evacuation
• Square end geometry with centercutting capability for direct plunge entry
• Uncoated finish suitable for a broad range of ferrous and non-ferrous workpiece materials
• 5/16-inch shank fits standard collet chucks and end mill holders

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 5/16-inch shank end mill holder or collet.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the machine tool manufacturer's specifications. Verify runout with a dial indicator before commencing the cut to avoid premature edge wear or tool breakage.
