Accupro 12177486 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177486 is a solid carbide tapered end mill designed for precision milling operations where angled walls and draft features are required. It features a 2-degree taper angle per side and a 3/16-inch small end diameter, with a 1-1/4-inch length of cut and a 3-flute, right-hand spiral geometry. The micrograin carbide substrate delivers edge retention and rigidity in demanding cuts. The square end profile suits flat-bottom pockets and contoured surfaces. This tool is installed by machinists and tooling technicians in CNC and manual milling environments where tight taper tolerances are required.

The 12177486 is suited for mold-making, die work, and general precision machining where tapered sidewalls are part of the part geometry. The 5/16-inch shank diameter fits standard ER and straight-bore collet systems. The 3-inch overall length provides clearance for moderate-depth work without sacrificing rigidity. The uncoated finish makes this tool appropriate for non-ferrous metals, plastics, and other materials where coating adhesion is not required or where re-sharpening is anticipated.

Key Features

• 2-degree taper angle per side for accurate draft and angled-wall milling
• Solid micrograin carbide construction for edge retention and rigidity
• 3-flute right-hand spiral geometry with 30-degree helix angle
• Square end profile for flat-bottom pockets and profiling
• Centercutting design allows plunge entry
• Uncoated finish suitable for non-ferrous alloys and regrinding

Compatibility

Designed for use in standard CNC and manual milling machines accepting a 5/16-inch shank via ER collet, straight-bore chuck, or equivalent toolholding system.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked before changing or seating the tool. Clean the collet bore and shank before tightening to the toolholder manufacturer torque specification. Verify taper angle and runout with a test indicator before cutting production parts.
