Accupro 12177450 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177450 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry and clean square-end profiles. Built from micrograin solid carbide, it delivers high rigidity and wear resistance across a range of workpiece materials. The tool features a 1-degree taper angle per side, a small end diameter of 5/64 inches, and a 1/2-inch length of cut. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing plunge entry, and runs right-hand flute direction. It is left uncoated, making it straightforward to inspect for wear during routine tool checks.

This tapered end mill is suited for CNC machining centers and manual mills performing profiling, slotting, and contour work where a taper wall angle is required. The 1/8-inch shank diameter fits standard collet systems commonly found in benchtop and production CNC setups. Its compact 2-1/4-inch overall length helps minimize runout and maintain rigidity in close-quarter setups. Typical applications include die and mold work, engraving, and finish profiling in aluminum, brass, plastics, and softer ferrous materials.

Key Features

• Micrograin solid carbide construction for high rigidity and extended tool life
• 1-degree taper angle per side for accurate tapered wall geometry
• Three spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand flute direction compatible with standard spindle rotation
• Uncoated finish for easy visual wear inspection

Compatibility

Designed as a direct-fit replacement for standard 1/8-inch shank collet systems on CNC machining centers and manual milling machines requiring a 1-degree-per-side tapered end mill.

Installation Notes

Installation should be performed by a qualified machinist following the machine manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Seat the 1/8-inch shank fully into a clean, properly sized collet or tool holder and torque the collet nut to the manufacturer's specified value. Verify runout with a dial indicator before beginning a cut to protect both the workpiece and the tool.
