Sgs 33105 Square End Mill 5/16 Inch 4 Flute Solid Carbide

Product Description

The SGS 33105 is a solid carbide square end mill designed for precision milling operations in a wide range of metalworking applications. Built from micrograin carbide stock, this single-end tool features a 5/16 inch cutting diameter, a 1-1/8 inch length of cut, and a 3 inch overall length. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and consistent surface finish. Variable index geometry reduces harmonics during cutting, helping to minimize chatter and extend tool life across demanding applications.

The SGS 33105 is well-suited for milling ferrous and non-ferrous metals, cast materials, high-temp alloys, and plastics, as indicated by its primary workpiece material codes covering material groups H, K, M, N, P, and S. The long-series 1L configuration provides extended reach for pocketing, slotting, and profiling where standard-length tools fall short. The centercutting design allows plunge entry, giving machinists added flexibility in full-profile and ramp-entry operations. The straight-cylindrical shank is compatible with standard collet chucks and end mill holders.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• 4-flute right-hand cut with 30-degree helix angle for efficient chip flow
• Variable index flute spacing reduces chatter and vibration
• Centercutting capable — supports plunge and ramp milling entry
• Long-series 1L geometry extends reach for deep pockets and slots
• Uncoated finish suits applications where coating compatibility or regrinding is a consideration

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 5/16 inch straight-cylindrical shank. Suitable for machining material groups H, K, M, N, P, and S as classified by the input specification data.

Installation Notes

Installation 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 to the full recommended engagement depth in the holder to minimize runout and avoid pullout under load. Verify tool runout with a dial indicator before beginning a production cut, and confirm feed and speed parameters match the workpiece material and depth of cut.
