Accupro 12177463 Tapered End Mill 1/4 in Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177463 is a solid carbide tapered end mill designed for precision milling operations requiring a controlled taper profile. It features a 1-degree taper angle per side, a 1/4 inch small end diameter, and a 3-flute spiral configuration with a right-hand flute direction and 30-degree helix angle. The square end geometry and centercutting capability make it suited for slot milling, ramping, and profiling in ferrous and non-ferrous materials. Built from micrograin solid carbide, this tool delivers rigidity and edge retention in demanding cutting environments. It is installed by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This tapered end mill is intended for applications where a precise taper wall is required, such as mold and die work, draft angle machining, and dovetail-adjacent profiling. The uncoated finish makes it a general-purpose option suitable for a range of workpiece materials where coating chemistry is not a requirement. With a 3/8 inch shank diameter, it fits standard collet chucks and tool holders common in job shop and production environments. The 3.25 inch length of cut and 5 inch overall length allow reach into moderately deep cavities without requiring extended-reach tooling.

Key Features

• 1-degree taper angle per side for controlled wall draft in mold, die, and cavity work
• Micrograin solid carbide construction for superior edge retention and rigidity
• 3-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry supports plunge entry and ramp milling operations
• Right-hand cut, right-hand flute direction for standard CNC spindle compatibility
• Uncoated finish suitable for general-purpose milling across a broad material range

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide tapered end mill for standard 3/8 inch collet chucks and tool holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 3/8 inch shank fully and evenly in the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature edge wear or tool failure.
