Accupro 12177433 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177433 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper profile. It features a 0.5 degree angle per side and a 1/16 inch small end diameter, making it well suited for fine detail work, die and mold cavities, and engraving applications. The three-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining rigidity. The square end configuration allows for clean floor finishing at the base of tapered walls. The bright, uncoated finish is appropriate for use in non-ferrous metals, graphite, and other materials where coating adhesion is not required.

This end mill is used in CNC machining centers and manual milling machines for die and mold work, engraving, and fine contouring where a slight wall draft angle is needed. The 0.5 degree taper per side allows gradual wall draft without sacrificing dimensional control. The 1/2 inch length of cut and 2-1/4 inch overall length keep the tool compact and resistant to deflection during light finishing passes. Machinists working in tool rooms, job shops, and prototype environments will find this tool appropriate for tight-tolerance detail work in soft to medium-hardness materials.

Key Features

• 0.5 degree taper angle per side for controlled wall draft in die and mold applications
• Micrograin solid carbide construction provides rigidity and wear resistance
• Three-flute right-hand spiral geometry supports chip evacuation and smooth cutting action
• Square end profile allows clean floor finishing at the base of tapered cavities
• Center-cutting capable, allowing plunge entry without a pre-drilled hole
• Bright, uncoated finish suitable for non-ferrous metals, graphite, and similar materials

Compatibility

Designed as a direct-fit tapered end mill for standard 1/8 inch collet chucks and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard tooling practices. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8 inch shank fully and evenly in a matched collet or end mill holder and secure to the torque specification called out in the machine tool manufacturer documentation. Verify runout with a dial indicator before beginning a cut, as even minor runout amplifies deflection at small diameters.
