Accupro 12177520 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177520 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. Built from micrograin carbide stock, this tool features a 5-degree taper per side, a 3/32-inch small end diameter, and a 1-inch length of cut. The three-flute, right-hand spiral configuration promotes efficient chip evacuation during profiling, slotting, and contouring passes. The square end geometry makes it suitable for producing flat-bottomed features in mold, die, and general machining applications. The uncoated finish is appropriate for a range of workpiece materials where coating interactions must be avoided.

This end mill is used in CNC machining centers and manual mills where draft angles or tapered wall features are required. Common applications include mold cavities, die components, tapered slots, and angled wall contours in both prototype and production environments. With a 5/16-inch shank diameter and 3-inch overall length, it fits standard toolholders used in light to medium machining setups. Machinists, toolmakers, and CNC programmers working in job shops, mold shops, and production facilities are the primary users.

Key Features

• 5-degree taper per side for controlled draft angle geometry
• Micrograin solid carbide construction for rigidity and wear resistance
• 3-flute right-hand spiral design promotes chip flow and surface finish
• 30-degree helix angle balances cutting efficiency with tool stability
• Center-cutting capable, allowing plunge entry where needed
• Uncoated finish suitable for applications where bare carbide is preferred

Compatibility

Designed as a standard tapered end mill replacement for CNC and manual milling operations requiring a 5/16-inch shank with a 5-degree-per-side taper profile and 3/32-inch small end diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle before changing tooling. Seat the 5/16-inch shank fully in a collet or end mill holder and torque the retention hardware to the toolholder specification. Inspect the cutting edges for chips or runout before initiating any cutting pass.
