Accupro 12277034 Square End Mill 0.025 in 4 Flute Carbide

Product Description

The ACCUPRO 12277034 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in CNC machining centers and manual milling machines. At 0.025 inches in diameter with a 0.037-inch length of cut, this tool is built for micro-milling operations where tight tolerances and controlled material removal are critical. The micrograin carbide substrate supports rigidity at small diameters, and the bright uncoated finish keeps the tool geometry sharp for general-purpose cutting. Four flutes and a 30-degree helix angle provide a balance of chip evacuation and surface finish quality. Licensed machinists and CNC operators install and apply this tool.

This end mill is suited for small-feature work including slots, pockets, and contours in precision machined components. Its 0.125-inch shank diameter fits standard collets used across most CNC milling setups. With a 1.5-inch overall length and single-end configuration, it is appropriate for shallow-depth micro-milling applications in tool-and-die, mold making, medical device manufacturing, and electronics component machining where small diameter and controlled depth of cut are required.

Key Features

• 0.025-inch mill diameter for micro-milling and fine-detail work
• Micrograin solid carbide construction for rigidity and wear resistance at small diameters
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Right-hand cutting and right-hand flute direction for standard CNC spindle compatibility
• Center-cutting capability allows plunge entry
• Bright uncoated finish suitable for general-purpose milling across a range of materials

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills equipped with standard collet systems accepting a 0.125-inch shank diameter. Part of the ACCUPRO ASQSC4-CC-30H series.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet and torque the collet nut to the machine manufacturer specification. At 0.025-inch diameter, tool runout tolerance is critical — verify runout with a dial indicator before cutting to avoid premature tool breakage.
