Accupro 12177443 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177443 is a solid carbide tapered end mill designed for precision milling operations that require a controlled taper profile. It features a 0.5 degree taper angle per side with a 1/4 inch small end diameter and a 1-1/4 inch length of cut. The 3-flute spiral geometry with a 30 degree helix angle promotes efficient chip evacuation in a range of materials. The micrograin carbide construction provides edge retention and rigidity. This tool is installed by machinists and toolroom technicians in CNC machining centers and manual milling machines.

This tapered end mill is suited for profiling dovetail-adjacent features, draft angle walls, and tapered slots in both production and prototype environments. The square end geometry allows flat-bottom cutting at the tip. The right-hand flute direction is compatible with standard spindle rotation on conventional vertical and horizontal milling setups. The uncoated finish makes it well suited for aluminum, brass, and other non-ferrous materials, as well as light steel applications where a coating is not required.

Key Features

• 0.5 degree taper angle per side for controlled wall draft
• Solid micrograin carbide construction for rigidity and edge retention
• 3 spiral flutes with 30 degree helix angle for efficient chip removal
• Center-cutting capable for plunge entry
• Right-hand cut, right-hand flute direction for standard CNC and manual mill spindles
• Uncoated finish suited for non-ferrous metals and general-purpose milling

Compatibility

Designed as an OEM-style replacement and standard tooling selection for CNC machining centers and manual milling machines accepting a 1/4 inch straight shank tool holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Secure the 1/4 inch shank in a collet or end mill holder to the depth recommended by the holder manufacturer, ensuring adequate shank engagement. Verify taper angle requirements against the part drawing before use, as taper geometry cannot be corrected after cutting.
