Robbjack C1-201-18 Square End Mill 9/16 in 2 Flute Carbide

Product Description

The ROBBJACK C1-201-18 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 9/16-inch diameter, 1-1/4-inch length of cut, and 3-1/2-inch overall length, this tool handles slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation, reducing heat buildup and tool wear. Centercutting capability allows plunge entry directly into the workpiece. This end mill is uncoated solid carbide in material grade C2, offering rigidity and wear resistance for general-purpose milling applications. Machinists and CNC operators in job shops and production environments are the primary users.

The C1-201-18 fits standard milling applications where a regular-length, right-hand cut, right-hand flute end mill is required. The 9/16-inch shank diameter matches the mill diameter for direct collet or end mill holder mounting in milling machines and machining centers. Its 2-flute design suits softer metals and materials where chip clearance is a priority, as well as general steel milling at appropriate feed and speed parameters. The uncoated finish makes it a cost-effective choice for shops running general-purpose material removal without requiring specialized coatings.

Key Features

• 9/16-inch cutting diameter with 1-1/4-inch length of cut for standard milling reach
• Solid carbide construction, material grade C2, for rigidity and wear resistance
• 2-flute spiral geometry with 30-degree helix angle for effective chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Uncoated finish suited for general-purpose milling without specialty coating requirements

Compatibility

Designed as an OEM-style solid carbide square end mill in the ROBBJACK C1-201 series, compatible with collet chucks and end mill holders accepting a 9/16-inch shank diameter on standard vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation and operation of this end mill should be performed by qualified machinists familiar with CNC or manual milling equipment. Power down and lock out the spindle before mounting or removing the tool. Ensure the collet or tool holder is clean, undamaged, and properly torqued to the machine manufacturer's specification before running. Do not exceed the tool's rated depth of cut or length of cut for the material being machined.
