Accupro 12177525 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177525 is a solid carbide tapered end mill designed for precision milling operations where draft angles and tapered wall features are required. Built from micrograin carbide, it offers the hardness and edge retention needed for demanding cutting applications in steel, aluminum, and engineered plastics. The tool features a 5-degree taper per side, a 1/8-inch small end diameter, and a 1-1/4-inch length of cut, making it well suited for tight-tolerance die and mold work. Three spiral flutes with a 30-degree helix angle support efficient chip evacuation. The bright uncoated finish is standard for general-purpose carbide cutting.

This end mill is used in CNC machining centers and manual knee mills where tapered cavity walls, mold drafts, or angled slot features must be cut to precise dimensions. It fits applications in tool-and-die shops, mold making, aerospace component machining, and general job shop work. The 3/8-inch shank diameter accommodates standard collet chucks and end mill holders common in both vertical and horizontal machining setups. Right-hand flute direction and centercutting capability allow for plunge entry and ramping operations without a pre-drilled pilot hole.

Key Features

• 5-degree taper per side for accurate draft angles and tapered wall milling
• Micrograin solid carbide construction for hardness and long edge life
• 3 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge and ramp entry
• Bright uncoated finish suitable for general-purpose carbide applications
• Right-hand cut with 3/8-inch shank for compatibility with standard toolholders

Compatibility

Designed as a standard-shank tapered end mill compatible with 3/8-inch collet chucks, ER collet systems, and end mill holders used in CNC machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully into the toolholder to the recommended gauge line before tightening to prevent runout. Verify spindle speed and feed rate settings against the material being cut before engaging the workpiece. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fail suddenly if run on a damaged edge.
