Accupro 12177522 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177522 is a solid carbide tapered end mill designed for precision milling of angled walls, draft surfaces, and tapered features in metal, composite, and hard material workpieces. It runs a 5-degree taper per side with a 3/32-inch small end diameter, a 2-inch length of cut, and a 1/2-inch straight shank. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining cut stability. Micrograin carbide construction gives this tool durability and edge retention in demanding machining environments. It is centercutting, allowing plunge entry. Machinist and CNC operators install and run this tool in vertical machining centers and CNC milling equipment.

This end mill is suited for creating tapered pockets, mold cavities, die features, and draft-angle walls in production and job-shop environments. The square end geometry delivers clean floor finishes at the base of the cut. The uncoated finish makes it a cost-effective choice for shops that prefer to apply their own surface treatments or that run materials where specific coatings are unnecessary. At 4 inches overall length, it provides adequate reach for medium-depth tapered features without sacrificing rigidity.

Key Features

• 5-degree taper per side for accurate draft-angle and tapered-wall milling
• Solid micrograin carbide construction for edge retention and wear resistance
• Three right-hand spiral flutes with 30-degree helix for efficient chip removal
• Centercutting capable - supports plunge entry without a pilot hole
• Uncoated finish compatible with a wide range of workpiece materials
• 1/2-inch shank fits standard ER and side-lock toolholders

Compatibility

Designed as a standard tapered end mill for use in CNC vertical machining centers and manual mills equipped with a 1/2-inch collet or toolholder. No specific model compatibility data was provided in the product input.

Installation Notes

Installation and tool changes must be performed with the machine powered down and the spindle fully stopped. Seat the 1/2-inch shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before committing to a production cut. Follow your facility's lockout/tagout procedures before any tool change.
