Accupro 14797179 Square End Mill 1mm 3 Flute Carbide

Product Description

The ACCUPRO 14797179 is a solid carbide square end mill designed for precise milling in tight tolerances and small-feature work. Built from micrograin carbide, it runs at 1 mm (0.0394 inches) cutting diameter with a 0.059-inch length of cut and a 0.125-inch shank diameter. The three-flute geometry with a 30-degree right-hand spiral helix balances chip evacuation and rigidity. The bright, uncoated finish suits applications where coating buildup or heat from coating processes is a concern. This is a single-end, centercutting tool capable of plunge, slot, and peripheral milling operations in ferrous and non-ferrous materials.

This end mill is sized for micro-milling applications where fine detail and dimensional accuracy are required. The 2.5-inch overall length with extended reach geometry makes it suitable for accessing recessed features. It is used by machinists and tool-and-die professionals in CNC machining centers, manual mills, and precision grinding setups. The right-hand cutting direction is compatible with conventional CNC spindle configurations. No coolant-through capability means it is best paired with flood, mist, or air-blast cooling applied externally during operation.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance at small diameters
• 1 mm cutting diameter with a tight mill diameter tolerance of plus 0.0000 / minus 0.0010 inches
• 3-flute, 30-degree right-hand helix for efficient chip flow in small-feature cuts
• Centercutting design allows direct plunge entry into workpiece material
• Extended reach geometry with 0.117-inch reach length for recessed feature access
• Bright, uncoated finish — no coating-related dimensional variation on the cutting edge

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.125-inch round shank. Part of the ACCUPRO ASQSC3-CCER series of square end mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked. Ensure the tool holder collet or chuck is clean and within tolerance before seating the 0.125-inch shank. Confirm runout with a dial indicator after clamping, as small-diameter carbide tools are sensitive to concentricity errors. Do not use this tool without appropriate workholding and chip management in place.
