Sgs 30133 Square End Mill 17/64 in 4 Flute Solid Carbide

Product Description

The SGS 30133 is a single-end, square-profile solid carbide end mill designed for precision milling operations across a wide range of metalworking applications. It features a 17/64 inch (0.2656 inch) cutting diameter, a 3/4 inch length of cut, and a 4-flute, right-hand spiral configuration with a 30-degree helix angle. The micrograin carbide construction delivers the rigidity and wear resistance required for consistent performance in production environments. This tool is centercutting, allowing plunge entry, and carries a variable index geometry that helps reduce harmonic vibration during cut.

The SGS 30133 is suited for milling operations on a broad range of workpiece materials, including hardened steels, cast irons, stainless steels, non-ferrous metals, and high-temperature alloys, as indicated by its primary material codes H, K, M, N, P, and S. The straight-cylindrical shank measures 5/16 inch in diameter, making it compatible with standard collet and end mill holders in CNC machining centers and manual knee mills. It is classified as a regular-length end mill with a 2.5 inch overall length.

Key Features

• 17/64 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance work
• 4-flute, right-hand spiral flute design with 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and extended tool life
• Centercutting geometry allows direct plunge milling without pre-drilling
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Bright/uncoated finish; suitable for use with or without cutting fluid

Compatibility

Designed for use with standard 5/16 inch collets and end mill holders in CNC machining centers and manual milling machines. Compatible with workpiece materials in SGS material codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous alloys, soft metals, and high-temperature superalloys.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the end mill. Seat the straight-cylindrical shank fully and concentrically in the holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after seating to confirm proper alignment prior to cutting.
