Accupro 12177500 Tapered End Mill 3/32 in Solid Carbide

Product Description

The ACCUPRO 12177500 is a solid carbide tapered end mill designed for precision milling operations requiring tight angular geometry and clean square-end profiles. Built from micrograin carbide stock, this tool holds a 3-degree taper per side and features three right-hand spiral flutes with a 30-degree helix angle. The small end diameter measures 3/32 inches, the length of cut is 2 inches, and the overall length is 4 inches. The uncoated finish makes it straightforward to inspect for wear and suitable for use in a range of base materials. Machinists and tool-and-die professionals reach for this tool when slot milling, profiling, or cutting tapered pockets that demand dimensional accuracy.

This tapered end mill is suited for CNC machining centers and manual knee mills running operations in ferrous and non-ferrous materials where a fine small-end diameter and consistent taper geometry are required. The 5/16-inch shank diameter fits standard collets and end mill holders common in production and job shop environments. Its centercutting capability allows plunge entry, broadening its use across contour milling, 3D profiling, and die-cavity work where the tapered wall angle must match a specified draft.

Key Features

• 3-degree taper per side for precise draft angle control in tapered slots and pockets
• Micrograin solid carbide construction for rigidity and extended tool life
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Uncoated finish for easy wear inspection and compatibility with standard cutting fluids
• Square end profile produces flat-bottomed cuts with sharp corner definition

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide tapered end mill for CNC machining centers and manual mills accepting a 5/16-inch shank diameter in standard collet or end mill holder tooling systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing tooling. Seat the 5/16-inch shank fully into a clean, properly sized collet or end mill holder and torque the retention system per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, and confirm that spindle speed and feed rate are set according to the material being machined and the tool manufacturer's recommended cutting data.
