Sgs 43307 Square End Mill 0.1969 in 2 Flute Solid Carbide

Product Description

The SGS 43307 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. It features a 0.1969 inch (5 mm) diameter with a 0.9843 inch (25 mm) length of cut, making it well suited for deep-slot and extended-reach operations where standard-length tools fall short. The 30-degree helix angle and two-flute spiral geometry promote efficient chip evacuation and reduced cutting forces. Manufactured from micrograin solid carbide with a bright uncoated finish, it delivers rigidity and wear resistance across a broad range of workpiece materials. Machinists and CNC operators rely on this type of tool for tight-tolerance profiling, slotting, and contouring work.

The SGS 43307 belongs to the Series 3XLM extra-long end mill family. It is intended for use in CNC machining centers and manual milling machines where extended reach into cavities, pockets, or deep features is required. The tool carries primary workpiece material codes H, K, M, N, P, and S, covering hardened steels, cast irons, stainless steels, non-ferrous metals, general steels, and superalloys. Its straight-cylindrical shank fits standard ER collets and end mill holders. The centercutting geometry allows plunge entry as well as conventional peripheral milling passes.

Key Features

• 0.1969 inch (5 mm) mill diameter with matching 0.1969 inch straight-cylindrical shank
• 0.9843 inch (25 mm) extra-long length of cut for deep-reach applications
• 30-degree helix angle with right-hand spiral flute and right-hand cut direction
• Two-flute design promotes chip clearance in slotting and pocket milling
• Micrograin solid carbide construction — bright uncoated finish, no chipbreaker, no variable helix
• Centercutting capable — supports plunge, slot, and profile operations

Compatibility

Designed as a direct-fit replacement or standard tooling addition for CNC machining centers and manual mills using ER collets or end mill holders sized for a 0.1969 inch (5 mm) straight-cylindrical shank. Compatible with workpiece materials designated under codes H, K, M, N, P, and S as defined by the SGS Series 3XLM selection guidelines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Seat the shank to the recommended engagement depth in the collet or holder — insufficient engagement on a small-diameter tool increases deflection risk. Verify runout with a dial indicator before beginning a production cut, as micrograin carbide is sensitive to interrupted cuts caused by excessive runout or loose clamping.
