Accupro 12177535 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177535 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper profile. It features a 7-degree taper angle per side, a 1/8-inch small end diameter, and a 1/2-inch length of cut. The three-flute, right-hand spiral geometry with a 30-degree helix angle provides efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers the hardness and wear resistance needed for demanding machining applications. The square end geometry supports flat-bottom profiling and contour work in mold, die, and general precision machining environments. This tool ships uncoated and is center-cutting capable.

This tapered end mill is suited for CNC machining centers and manual milling operations where draft angles, tapered walls, or angled cavity profiles are required. Typical applications include mold and die work, aerospace component finishing, and precision part profiling where a consistent 7-degree-per-side taper must be held. The 1/4-inch shank diameter fits standard ER collet chucks, end mill holders, and milling machine spindles commonly found in job shops and production facilities. The 3-inch overall length provides adequate reach for moderate-depth cavity work without sacrificing rigidity.

Key Features

• 7-degree taper angle per side for consistent draft wall geometry
• Micrograin solid carbide construction for hardness and edge retention
• Three right-hand spiral flutes with 30-degree helix for efficient chip removal
• Center-cutting capable — supports plunge entry
• Square end profile for flat-bottom and contour milling
• Uncoated finish suitable for non-ferrous, graphite, and general-purpose machining

Compatibility

Designed as a standard tapered end mill for use in CNC machining centers and manual mills equipped with a 1/4-inch collet, end mill holder, or compatible tooling system that accepts a 1/4-inch round shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Verify collet size and holding torque specifications match the toolholder manufacturer's recommendations before engaging a cut. Inspect the cutting edges for chips or damage prior to each use; carbide end mills are brittle and should not be used if edge chipping is observed.
