Micro 100 SFA-250-46 Square End Mill 1/4 in 1 Flute Carbide

Product Description

The MICRO 100 SFA-250-46 is a single-flute, solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut (LOC), and a 2.5 inch overall length (OAL). The 30-degree helix angle and right-hand cutting direction support clean chip evacuation and smooth cutting performance. The bright, uncoated finish makes this tool well-suited for applications where coating buildup or heat retention must be minimized. Machinists and CNC operators working with non-ferrous metals, plastics, and composites are the primary users of this tool.

The SFA-250-46 is intended for use in milling machines and CNC machining centers where a single-flute end mill is preferred for maximizing chip clearance, particularly in softer materials or slotting operations where chip re-cutting is a concern. Its 1/4 inch shank diameter fits standard collets and tool holders commonly found in both manual and CNC setups. The single-end configuration makes it a direct-use tool without the option to flip and re-use, keeping setup straightforward.

Key Features

• 1/4 inch cutting diameter with 3/4 inch length of cut for controlled depth engagement
• Single flute design maximizes chip clearance in softer materials and slotting applications
• 30-degree helix angle supports smooth cutting action and efficient chip evacuation
• Solid carbide construction provides rigidity and wear resistance over high-speed cuts
• Bright, uncoated finish suitable for non-ferrous metals, plastics, and composites
• Right-hand cut and right-hand flute direction for use in standard spindle setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for milling machines and CNC machining centers accepting a 1/4 inch shank diameter toolholder or collet.

Installation Notes

Installation of end mills should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth to prevent pullout during cutting. Verify spindle speed and feed rate settings are appropriate for the workpiece material before beginning a cut.
