Accupro 12177438 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177438 is a solid carbide tapered end mill designed for precision milling operations where draft angles and tapered walls are required. It features a small end diameter of 0.125 inches, a 0.5-degree taper angle per side, and a 3-flute spiral configuration that promotes efficient chip evacuation and smooth surface finishes. The 30-degree helix angle and micrograin carbide construction deliver rigidity and edge retention in demanding cutting conditions. This tool is installed and operated by machinists and CNC programmers working on mold, die, and precision component applications.

This tapered end mill is suited for CNC machining centers and manual mills where tapered wall geometry is needed on ferrous and non-ferrous materials. With a 0.75-inch length of cut and a 2-inch overall length, it fits standard toolholding setups with a 0.25-inch shank. The centercutting geometry allows plunge entry, expanding its application range. It is a common choice in mold-making, aerospace component machining, and precision part manufacturing where controlled taper is a print requirement.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 0.5-degree taper angle per side for precise drafted wall geometry
• 3-flute right-hand spiral with 30-degree helix angle for efficient chip removal
• Centercutting capable - supports direct plunge entry
• Uncoated finish suitable for use with cutting fluids on a wide range of materials
• Square end profile for flat-bottom tapered pockets and walls

Compatibility

Designed for use in standard 1/4-inch collet or end mill holders on CNC machining centers and manual mills requiring a tapered end mill with a 0.125-inch small end diameter and 0.25-inch shank.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is seated completely in a clean, undamaged collet or end mill holder before tightening. Verify runout with a dial indicator before commencing a cut. Follow applicable shop safety procedures and machine manufacturer guidelines when setting tool offsets and feeds and speeds for carbide tooling.
