Sgs 00335 Square End Mill 0.039 in 2 Flute Solid Carbide

Product Description

The SGS 00335 is a square-end, single-end solid carbide end mill designed for precision milling operations in ferrous and non-ferrous materials. With a cutting diameter of 0.039 inches and a 2-flute spiral geometry at a 30-degree helix angle, this tool is built for fine-detail slotting, profiling, and contouring in tight-tolerance applications. The micrograin carbide construction provides the rigidity and edge retention needed at small diameters where tool deflection is a concern. Center-cutting capability allows plunge entry as well as conventional lateral cutting passes.

This end mill is suited for use on CNC machining centers, manual mills, and precision benchtop machines in shop environments handling small-part or micro-machining work. The 0.125-inch straight cylindrical shank (h6 tolerance) fits standard collets and tool holders across common spindle configurations. Its regular-length classification and 1.5-inch overall length make it appropriate for shallow-to-moderate depth cuts where clearance above the workpiece is not a limiting factor.

Key Features

• Micrograin solid carbide construction for superior edge retention at small diameters
• 2-flute spiral geometry with 30-degree right-hand helix for efficient chip evacuation
• Center-cutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for a wide range of base materials
• Straight cylindrical shank with h6 tolerance for precise collet fitment
• Mill diameter tolerance of +0.000 to -0.001 inches for consistent dimensional accuracy

Compatibility

Designed as a standard-shank replacement end mill for use in any machine spindle or collet system accepting a 0.125-inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth before torquing the retention hardware. Verify runout with a dial indicator after seating, particularly critical at this diameter, as even minor runout will reduce tool life and dimensional accuracy.
