Accupro 12177452 Tapered End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12177452 is a solid carbide tapered end mill designed for precision milling operations requiring controlled taper geometry. Built from micrograin carbide stock, it features a 1-degree taper angle per side and a 3/32-inch small end diameter, making it well suited for fine detail work in tight cavities and contoured surfaces. With 3 spiral flutes in a right-hand direction and a 30-degree helix angle, the tool promotes efficient chip evacuation and smooth cutting action. The uncoated finish makes it appropriate for a range of ferrous and non-ferrous materials where coating is not required or preferred.

This end mill is used in CNC machining centers and manual mills where tapered walls, draft angles, or narrow slot profiles are required. The centercutting capability allows plunge entry, expanding its utility in die and mold work, fixture machining, and detailed part contouring. With a 1/8-inch shank diameter and 2-1/4-inch overall length, it fits standard collet systems and tool holders used in production and job-shop environments. Machinists and tool-and-die professionals working in aerospace, mold making, and precision manufacturing are the primary users.

Key Features

• 1-degree taper angle per side for controlled draft and tapered wall geometry
• 3/32-inch small end diameter for fine detail cutting in narrow features
• 3/4-inch length of cut (LOC) provides adequate flute engagement for most light-duty taper milling passes
• Micrograin solid carbide construction for rigidity and edge retention
• Right-hand, 30-degree helix spiral flutes promote chip flow and reduce recutting
• Centercutting design allows direct plunge entry without pre-drilling
• Uncoated finish suitable for applications where coating is not specified

Compatibility

Designed as a standard taper end mill replacement for CNC machining centers and manual mills using 1/8-inch collets or compatible tool holders requiring a tapered solid carbide end mill with a square end profile.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Seat the 1/8-inch shank fully and evenly in the collet or tool holder before tightening to the tool holder manufacturer's specified torque. Inspect the cutting edges for chips or damage before each use. Follow your machine's speed and feed guidelines for solid carbide tooling and the specific workpiece material being cut.
