Accupro 12177445 Tapered End Mill 3/8 in Solid Carbide Square

Product Description

The ACCUPRO 12177445 is a solid carbide tapered end mill designed for precision milling of angled surfaces, chamfers, and draft features in metalworking and moldmaking applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cuts. The tool features a 0.5-degree taper per side, a 3/8 inch small end diameter, and a 7/16 inch shank diameter, with a 1-1/4 inch length of cut and a 4 inch overall length. Three right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The uncoated finish suits operations where coating is not required or where re-sharpening is anticipated.

This tapered end mill is suited for CNC machining centers and manual mills used in tool and die, mold, and general precision machining environments. Its square end profile and centercutting capability make it appropriate for plunge entries and contour work on ferrous and non-ferrous materials. Machinists and toolroom operators working on angled pockets, taper walls, and die relief cuts will find this geometry directly applicable to production and prototype work.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 0.5-degree taper per side for precise angled wall and draft machining
• Three right-hand spiral flutes with 30-degree helix for efficient chip removal
• Centercutting design allows direct plunge entry into workpiece
• Square end profile suitable for flat-bottom tapered pockets and contours
• Uncoated finish compatible with re-sharpening workflows

Compatibility

Designed as a standard tapered end mill for use in CNC machining centers and manual milling machines accepting a 7/16 inch round shank via collet, end mill holder, or equivalent toolholding system.

Installation Notes

Installation should be performed by a qualified machinist following the toolholding manufacturer's torque and runout specifications. Ensure the shank is fully seated and secure in the collet or holder before spindle engagement. Verify spindle speed and feed rate are set per the material and operation requirements before cutting. Inspect the cutting edges for chips or damage before each use, as carbide tools are brittle and should not be used if edge integrity is compromised.
