Accupro 12177487 Tapered End Mill 1/4 in Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177487 is a solid carbide tapered end mill designed for precision milling applications where controlled taper geometry is required. The tool features a 1/4 inch small end diameter, a 2 degrees taper angle per side, and a 3/4 inch length of cut. Constructed from micrograin solid carbide, it delivers rigidity and edge retention in demanding cutting conditions. The square end profile and right-hand spiral flutes make it suitable for finishing passes and contour work in ferrous and non-ferrous materials. Installation and operation require a compatible 3/8 inch collet or toolholder.

This end mill is suited for CNC machining centers and manual mills where tapered wall features, draft angles, or mold cavity work are required. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during profiling operations. With centercutting capability, this tool can plunge directly into the workpiece, broadening its use across roughing entry and finish profiling in tool steels, aluminum, and similar materials. Machinists and tool-and-die professionals working in production or job shop environments will find this geometry well suited to fine detail work.

Key Features

• 2 degrees taper angle per side for controlled draft and tapered wall geometry
• Micrograin solid carbide construction for extended tool life and edge stability
• 3 right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Square end profile suitable for floor finishing and profiling passes
• Uncoated finish - compatible with a wide range of cutting fluids and materials

Compatibility

Designed as a standard-shank tapered end mill with a 3/8 inch shank diameter, compatible with ER collets, milling chucks, and precision toolholders sized for 3/8 inch shank tooling on CNC or manual milling machines.

Installation Notes

This tool should be installed by a qualified machinist or CNC setup technician using a clean, properly sized collet or toolholder to ensure runout is minimized. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Do not exceed the recommended depth of cut for the material being machined. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds.
