Accupro 12185171 Square End Mill 0.0984 in 4 Flute Carbide

Product Description

The ACCUPRO 12185171 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. The double-end configuration provides two usable cutting ends, extending tool life before replacement. At 0.0984 inches (2.50 mm) in diameter with a 0.1969-inch (5.00 mm) length of cut, this stub-length tool offers rigidity and reduced deflection in tight-tolerance machining operations. The four-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance. Machinists and CNC operators in production and job-shop environments are the primary users.

This end mill is suited for slotting, profiling, and light plunge cuts in applications where a small-diameter, stub-length tool is required. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. The micrograin carbide substrate supports fine surface finishes and dimensional accuracy on close-tolerance features. Typical applications include mold and die work, fixture machining, and precision part production where tool rigidity at small diameters is critical.

Key Features

• Double-end design provides two cutting ends per tool, reducing cost per edge
• TiCN coating increases hardness and wear resistance compared to uncoated carbide
• Micrograin solid carbide substrate supports tight-tolerance and fine-finish cuts
• 30-degree right-hand spiral flute promotes chip evacuation and reduces cutting forces
• Centercutting geometry enables direct plunge entry without pilot drilling
• Stub length provides maximum rigidity and minimizes deflection at small diameters

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers, manual mills, and tool-and-die setups that accept a 3.00 mm (0.1181 inch) shank diameter with standard collet or end mill holder systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the full recommended grip depth in the collet or holder and verify runout before beginning production cuts. Do not exceed the manufacturer-rated depth of cut or feed rate for the diameter and material being machined.
