Sgs 70529 Ball End Mill 4 Flute 0.1575 in Solid Carbide

Product Description

The SGS 70529 is a solid carbide ball end mill designed for precision finishing operations in demanding machining environments. This single-end, 4-flute tool measures 0.1575 inches (4 mm) in cutting diameter with a length of cut of 0.9843 inches (25 mm) and an overall length of 2.9528 inches (75 mm). The 4 mm shank diameter keeps the tool compatible with standard collet systems. An AlTiN coating provides thermal resistance and extended tool life when cutting hard and exotic materials. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces during finishing passes. Micrograin carbide construction delivers rigidity and edge sharpness required for tight-tolerance work.

This end mill is intended for finishing cuts in materials classified under ISO workpiece material codes H, K, M, P, and S — covering hardened steels, cast irons, stainless steels, general steels, and superalloys. Its long-series designation provides additional reach for applications requiring deeper cavity work or extended projection from the holder. The variable index design reduces harmonic chatter during operation, making it well suited for high-speed machining centers and CNC milling applications where surface finish is critical. Installed by machinists and tool-and-die professionals in production and job-shop environments.

Key Features

• AlTiN coating for high-temperature resistance and extended tool life in hard and exotic materials
• 4-flute, single-end ball nose geometry optimized for finishing operations
• 38-degree high helix angle promotes effective chip evacuation and smooth cutting action
• Variable index flute spacing reduces chatter and improves surface finish
• Micrograin solid carbide substrate for rigidity and sharp, durable cutting edges
• Long-series length type provides additional reach for deeper cavity and mold work

Compatibility

The SGS 70529 belongs to the Series 7MB product family and is suitable for use in standard 4 mm collet or shrink-fit toolholders on CNC milling machines. Compatible workpiece materials include those coded H, K, M, P, and S per ISO material classification.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the spindle and machine are fully de-energized and at a complete stop before changing tooling. Verify shank runout within the collet or holder before commencing cuts, as excessive runout will accelerate edge wear on small-diameter carbide tools. Follow shop-specific feeds, speeds, and depth-of-cut parameters appropriate for the workpiece material and machine rigidity.
