Accupro 12177550 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177550 is a solid carbide tapered end mill designed for precision milling operations where consistent taper geometry and surface finish are required. Built from micrograin solid carbide, this tool delivers rigidity and wear resistance across a range of workpiece materials. It features a 10-degree taper per side, a 1/4-inch small end diameter, and a 2-inch length of cut. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The uncoated finish makes it suitable for applications where coating compatibility or regrinding flexibility is a consideration. Machinists, tool and die makers, and CNC operators are the primary users of this tool.

This tapered end mill is suited for mold making, die work, and contour milling applications where a consistent taper angle is critical to part geometry. It is centercutting, allowing plunge entry where required. With a 1-inch shank diameter and 5-inch overall length, it fits standard toolholders used in vertical machining centers and manual knee mills. The square end profile makes it appropriate for profiling and peripheral cutting passes requiring a flat floor at the base of the cut.

Key Features

• 10-degree taper per side for consistent tapered geometry on milled features
• Micrograin solid carbide construction for rigidity and extended tool life
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Uncoated finish supports regrinding and broad material compatibility
• Square end profile for flat-floor profiling and peripheral cuts

Compatibility

Designed for use in standard CNC and manual milling machines accepting a 1-inch straight shank toolholder. No specific model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or end mill holder with adequate retention torque before running. Verify runout with a dial indicator before cutting to protect tool life. Follow applicable shop safety procedures and machine manufacturer guidelines when handling carbide cutting tools.
