Sgs 43303 Square End Mill 0.1575 in 2 Flute Carbide 3XLM

Product Description

The SGS 43303 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 0.1575-inch cutting diameter, a 0.9843-inch length of cut, and a 2-flute spiral geometry at a 30-degree helix angle, this tool delivers efficient chip evacuation and clean edge profiles on a wide range of workpiece materials. The micrograin carbide substrate provides the hardness and wear resistance needed for consistent performance at tight tolerances. The straight-cylindrical shank measures 0.1575 inches in diameter and seats securely in standard collet or end mill holders. Rated as an extra-long series tool, the 43303 extends reach into deeper features without sacrificing rigidity. It is right-hand cut with right-hand flute direction, uncoated bright finish.

The SGS 43303 is suited for milling operations that require extended reach into pockets, slots, or stepped features where a standard-length end mill cannot reach. Compatible workpiece material codes include H, K, M, N, P, and S, covering a broad spectrum of materials such as hardened steels, cast irons, stainless steels, non-ferrous metals, carbon steels, and high-temperature alloys. This tool is appropriate for use in CNC machining centers and manual mills in production and job-shop environments. Its centercutting capability allows direct plunge entry as well as conventional side milling and slotting operations.

Key Features

• 0.1575-inch cutting diameter with matching 0.1575-inch straight-cylindrical shank for consistent tool runout
• 0.9843-inch length of cut in the extra-long 3XLM series for deep-pocket and extended-reach applications
• 2-flute spiral geometry at 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for hardness and edge retention across multiple workpiece materials
• Centercutting design permits plunge entry as well as ramping and slotting
• Bright uncoated finish, right-hand cut and flute direction, no chipbreaker or variable helix

Compatibility

The SGS 43303 is rated for workpiece material codes H, K, M, N, P, and S as specified by the manufacturer. It is part of the SGS Series 3XLM extra-long end mill family. No additional specific machine or toolholder model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within a calibrated collet or end mill holder to the recommended engagement depth before torquing the retention mechanism. Verify spindle runout at the cutting edge before beginning the operation, as runout on a small-diameter carbide tool accelerates wear and increases breakage risk. Never exceed the tool manufacturer's recommended speeds and feeds for the selected workpiece material and depth of cut.
