Sgs 32598 Corner Radius End Mill 5/8 in 5 Flute Altin

Product Description

The SGS 32598 is a solid carbide corner radius end mill built for demanding metal removal in steel, stainless steel, cast iron, superalloys, and titanium. It measures 5/8 inches in diameter with a 0.0300 inch corner radius and a 3/4 inch length of cut. The five-flute, single-end design supports both roughing and finishing operations. An AlTiN coating — designated Ti-NAMITE-A by SGS — provides thermal resistance and wear protection at high cutting speeds. The 45-degree high helix angle promotes efficient chip evacuation. Overall length is 3 inches with a 5/8 inch straight cylindrical shank. Variable index spacing reduces harmonic vibration during aggressive cuts. This tool is intended for use in end mill toolholders on CNC machining centers and manual mills operated by machinists and toolroom professionals.

The SGS 32598 Series 55C end mill is suited for milling steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. It also handles hard secondary workpiece materials (ISO group H). The short flute length and rigid five-flute geometry make it appropriate for slotting, profiling, and contouring applications where tool deflection must be minimized. Right-hand cutting direction and right-hand flute spiral are standard. This tool does not feature centercutting geometry, so plunge entry requires a pre-drilled entry point or ramping strategy.

Key Features

• AlTiN coating (Ti-NAMITE-A) for thermal resistance and extended tool life in ferrous and hard materials
• Five-flute variable index design reduces chatter and supports both roughing and finishing in a single tool
• 0.0300 inch corner radius protects the cutting edge and improves surface finish at workpiece corners
• 45-degree high helix angle promotes efficient chip evacuation and reduces cutting forces
• Solid carbide construction (Material Grade C2) provides rigidity in short-reach applications
• 5/8 inch straight cylindrical shank (tolerance h6) compatible with standard end mill toolholders

Compatibility

Designed for use with standard end mill toolholders. Compatible with CNC machining centers and manual mills accepting a 5/8 inch straight cylindrical shank. Suited for workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank to the minimum recommended insertion depth for the toolholder in use. This tool does not have centercutting capability — avoid direct plunge entry; use a ramping or helical interpolation entry strategy instead.
