Sgs 36347 Ball End Mill 7/16 in 4 Flute Solid Carbide Altin

Product Description

The SGS 36347 is a single-end ball end mill engineered for precision finishing operations in demanding metalworking applications. Built from micrograin solid carbide and finished with an AlTiN coating, this tool delivers hardness and thermal resistance needed for cutting hardened steels, stainless steels, titanium alloys, and cast irons. It measures 0.4375 inches in diameter with a 1 inch length of cut and a 2.75 inch overall length. The 4-flute configuration combined with a variable helix and variable index geometry reduces chatter and improves surface finish across a range of cutting conditions. Designed for right-hand cutting and right-hand flute direction, it is compatible with standard R8, CAT, BT, and HSK toolholders accepting a 7/16 inch shank.

This end mill is suited for finish milling, profiling, and contouring operations in CNC machining centers working with hardened steels (H), cast irons (K), stainless steels (M), carbon and alloy steels (P), and high-temperature superalloys (S). The regular-length profile and solid carbide construction make it a practical choice for tool and die shops, aerospace component manufacturers, and precision job shops running tight tolerances. No coolant-through capability is present, so flood or mist coolant at the periphery is the standard approach.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance at high cutting speeds
• AlTiN coating provides oxidation resistance and reduced friction in dry or near-dry cutting
• Variable helix and variable index design suppresses harmonic vibration and chatter
• 4-flute configuration optimized for finishing passes and fine surface quality
• Right-hand cut, right-hand spiral geometry for compatibility with standard CNC spindle direction
• Series Z1B with mill diameter tolerance of +0.0000 to -0.0020 inches for close-tolerance work

Compatibility

Designed as an OEM-style solid carbide ball end mill replacement for CNC machining applications requiring a 7/16 inch diameter, 4-flute finishing tool in the SGS Z1B series.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle and toolholder are fully powered down and locked before changing tooling. Confirm shank seating depth and runout with a dial indicator before initiating a cut. Refer to the machine tool manufacturer guidelines and applicable shop safety procedures when selecting feeds, speeds, and depth of cut for the workpiece material.
