Sgs 39068 Ball End Mill 0.625 in 4 Flute Solid Carbide Ticn

Product Description

The SGS 39068 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in a wide range of workpiece materials. Built from micrograin solid carbide and coated with titanium carbonitride (TiCN), it delivers consistent edge integrity and wear resistance across demanding cutting applications. The 0.625 inch cutting diameter pairs with a 1.25 inch length of cut, giving machinists sufficient reach for most cavity and profiling work without sacrificing rigidity. With a 4-flute, right-hand spiral configuration and a 30-degree helix angle, this tool balances chip evacuation with surface finish quality. It is suited for use in CNC machining centers and manual mills operated by skilled machinists and toolroom professionals.

The SGS 39068 is appropriate for machining a broad range of materials including hardened steels, cast irons, stainless steels, non-ferrous metals, non-metals, and high-temperature alloys, corresponding to ISO material codes H, K, M, N, P, and S. The regular-length geometry and 0.625 inch shank diameter make it a practical choice for standard toolholders in production and job-shop environments. Variable index flute spacing helps reduce harmonic chatter during aggressive cuts. It is sold as a single-end tool and does not feature coolant-through capability or a chipbreaker geometry.

Key Features

• Micrograin solid carbide construction for extended tool life and edge sharpness
• TiCN coating improves hardness, lubricity, and resistance to built-up edge
• 4-flute, 30-degree right-hand helix for balanced chip flow and surface finish
• Variable index flute spacing reduces chatter and improves stability
• Ball-end profile suited for 3D contouring, profiling, and radius-bottom slots
• Mill diameter tolerance of +0.000 to -0.002 inches for precise fit and finish

Compatibility

Designed for use in standard CNC machining centers and manual mills accepting a 0.625 inch shank; compatible with workpiece materials in ISO categories H, K, M, N, P, and S as specified for SGS Series 1B tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully in a collet or end mill holder to the recommended engagement depth before torquing the retention hardware. Verify runout at the tool tip before beginning a cut, as excessive runout accelerates wear and can cause premature edge failure. Always power down and lock out the spindle before changing or measuring tooling.
