Robbjack C1-201-06 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ROBBJACK C1-201-06 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Part of the C1-201 series, this tool features a 3/16-inch diameter with a matching 3/16-inch straight cylindrical shank, a 5/8-inch length of cut, and a 2-inch overall length. The 2-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and clean cutting performance. It is centercutting, allowing plunge entry into the workpiece. Uncoated solid carbide construction at material grade C2 delivers hardness and wear resistance suited to general-purpose milling applications. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is suited for slotting, profiling, and light plunging operations in ferrous and non-ferrous materials. The regular-length geometry and compact diameter make it well matched to detailed features, narrow slots, and contoured profiles where a smaller tool diameter is required. The right-hand flute and right-hand cut orientation are standard for conventional CNC machining center setups. It is sold individually and is appropriate for both prototype work and short-run production machining.

Key Features

• Solid carbide construction at material grade C2 for hardness and wear resistance
• 2-flute, right-hand spiral flute with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Uncoated finish suitable for general-purpose and non-ferrous milling applications
• Straight cylindrical shank for secure collet or end mill holder retention
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent dimensional accuracy

Compatibility

Designed as a standard straight-shank solid carbide end mill compatible with collet chucks, ER collets, and end mill holders sized for a 3/16-inch shank diameter on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Secure the shank to the full recommended engagement depth in the collet or holder to minimize runout and prevent tool pull-out during cutting. Verify tool runout with a dial indicator before beginning a production cut.
