Accupro 12177502 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177502 is a solid carbide tapered end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/8 inch small end diameter, a 3-degree taper per side, and a 1 inch length of cut, making it well suited for machining tapered walls, draft angles, and deep-pocket contours. With 3 right-hand spiral flutes and a 30-degree helix angle, it delivers efficient chip evacuation and smooth cutting action. The micrograin carbide construction provides the hardness and wear resistance required for tight-tolerance work. This tool is installed and operated by machinists and CNC tooling technicians.

This tapered end mill is used in vertical machining centers and CNC milling applications where draft angle features or tapered slot profiles are required. The 1/4 inch shank diameter fits standard collet toolholders commonly found in production and job-shop environments. The square end geometry allows clean floor finishing at the base of tapered cuts. Its 3 inch overall length provides adequate reach for typical die and mold work as well as general precision machining tasks. The uncoated finish makes it suitable for use with coolant in aluminum, brass, and mild steel applications.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 3-degree taper per side for accurate draft angle and tapered wall machining
• 3 right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Center-cutting capable, allowing direct plunge entry into workpiece material
• Square end geometry for clean floor finishing at the base of tapered cuts
• Uncoated finish compatible with coolant use across a range of materials

Compatibility

Designed as a standard tapered end mill with a 1/4 inch straight shank, compatible with ER and straight-bore collet toolholders used in CNC vertical machining centers and manual knee mills.

Installation Notes

This tool should be installed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and the collet or toolholder is clean and free of chips before seating the shank. Confirm runout with a dial indicator before engaging a cut, as excessive runout will accelerate edge wear on carbide tooling. Follow the machine manufacturer and toolholder torque guidelines when securing the collet nut.
