Accupro 12177584 Tapered Ball End Mill 3/32 in Solid Carbide

Product Description

The ACCUPRO 12177584 is a solid carbide tapered ball end mill designed for precision milling of contoured surfaces, cavities, and tapered walls in ferrous and non-ferrous materials. It features a 1.5 degree taper per side and a 3/32 inch small end diameter with a 3/64 inch nose radius, making it well suited for fine detail work in mold making, die work, and complex 3D profiling operations. The micrograin carbide construction provides hardness and wear resistance at elevated cutting speeds. Three right-hand spiral flutes with a 30 degree helix angle promote efficient chip evacuation and a smooth finish cut. This tool is installed by machinists and tool room technicians operating CNC mills and machining centers.

This end mill is suited for small-diameter tapered slot and profile work where blend quality and surface finish are critical. Typical applications include mold cavity finishing, core detail milling, and tapered wall contouring in materials such as tool steels, aluminum alloys, and engineering plastics. The uncoated finish makes it compatible with standard cutting fluid or dry cutting applications where coating interaction with the workpiece material is a concern. The 3/16 inch shank fits standard collet chucks and shrink-fit holders commonly used in CNC machining environments.

Key Features

• 1.5 degree taper per side for accurate tapered wall profiling
• Solid micrograin carbide construction for wear resistance and rigidity
• Ball end with 3/64 inch nose radius for fine contour and detail work
• 3 right-hand spiral flutes at 30 degree helix for smooth chip flow
• Centercutting capable for plunge and ramp entry
• Uncoated finish suitable for a wide range of workpiece materials

Compatibility

Designed as an OEM-style solid carbide tapered ball end mill for use in CNC machining centers and manual mills equipped with standard collet or shrink-fit toolholding systems accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before installing or removing the tool from the holder. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification. Inspect the cutting edges and nose radius for chipping before each use, as micrograin carbide is rigid but brittle under impact or excessive runout.
