Accupro 12177538 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177538 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. With a 7-degree taper angle per side and a 5/32-inch small end diameter, this tool produces accurate tapered walls and contoured features in a variety of workpiece materials. The 3-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and wear resistance needed for demanding machining applications. This tool is installed in milling machines by machinists and CNC operators working in job shops, tool rooms, and production environments.

This tapered end mill is suited for mold and die work, contour milling, and applications where tapered slots or walls are required. The square end profile allows for flat-bottomed cuts at the tip. With a 3/4-inch length of cut and a 3-1/2-inch overall length, it reaches into moderate-depth cavities while maintaining rigidity. The 3/8-inch shank fits standard milling chucks and collet systems. Right-hand flute direction and centercutting capability expand its versatility across a range of milling strategies.

Key Features

• 7-degree taper angle per side for accurate tapered wall geometry
• 5/32-inch small end diameter with square end profile for flat-bottomed cuts
• 3-flute spiral geometry with 30-degree helix for efficient chip evacuation
• Micrograin solid carbide construction for hardness and wear resistance
• Centercutting design allows plunge entry into the workpiece
• Right-hand cut, uncoated finish suitable for a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct-use tapered end mill compatible with standard milling machine spindles and collet systems accepting a 3/8-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3/8-inch shank fully and evenly in the collet or chuck and torque the retention system per the machine manufacturer's specifications. Verify runout with a dial indicator before beginning a cut, and confirm feeds and speeds are appropriate for the workpiece material and depth of cut.
