Sgs 33126 Ball End Mill 0.3125 in 4 Flute Solid Carbide

Product Description

The SGS 33126 is a solid carbide ball end mill designed for precision milling in metalworking and machining applications. With a 0.3125 inch (5/16 inch) mill diameter and a 1.625 inch length of cut, this tool delivers extended reach capability in a single-end configuration. The 4-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting action. Manufactured from micrograin solid carbide, the 33126 maintains edge integrity under demanding cutting conditions. The uncoated finish makes it well suited for applications where coating compatibility or re-sharpening is a factor. Variable index spacing helps reduce chatter and vibration during the cut.

The SGS 33126 is intended for use in CNC machining centers and manual mills where extra-long reach is required to access deep pockets, cavities, or contoured surfaces. Its primary workpiece material compatibility codes cover a broad range of materials including hardened steels, cast irons, stainless steels, non-ferrous materials, general steels, and superalloys (codes H, K, M, N, P, S). This makes it a versatile choice for job shops, tool and die work, and production machining environments. It is a single-end tool with no coolant-through capability.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• 4-flute, right-hand spiral design with 30-degree helix angle for efficient chip removal
• Extra-long length of cut (1.625 inches) for deep pocket and cavity access
• Variable index flute spacing reduces chatter and vibration
• Uncoated finish compatible with a wide range of workpiece materials and regrind service
• Tight mill diameter tolerance of +0.000 to -0.002 inches for accurate fitment

Compatibility

Compatible with workpiece material groups H (hardened steels), K (cast irons), M (stainless steels), N (non-ferrous materials), P (general steels), and S (superalloys) per the SGS Series 1ELB classification. Designed for use in standard 5/16 inch collets or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's recommended tool-holding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Use a properly sized collet or end mill holder that matches the 5/16 inch shank diameter to prevent runout. Verify tool projection and stick-out length against the application requirements before beginning the cut.
