2F Carbide Ball Nose – Steel

2 Flute Solid Carbide Ball Nose End Mill for Steel – Standard Length – up to 55HRC

The Stiger standard length 2 flute ball nose end mill is a solid carbide cutter for 3D machining in steel. It is rated for materials up to 55HRC, so it handles carbon steels, alloy steels, tool steels and pre-hardened materials. The short overall length gives maximum rigidity and minimal tool deflection. That translates into tighter tolerances, a better surface finish and higher cutting parameters.

The full-radius ball end produces smooth, accurate curved surfaces. Two flutes leave generous chip space for clean evacuation. Use it for 3D profiling, contouring, copy milling, cavity work, fillets and radiused grooves wherever reach isn’t the limiting factor.

Features

• Solid carbide construction – high rigidity, wear resistance and consistent accuracy
• Machines steels up to 55HRC – from mild steel to pre-hardened and heat-treated material
• Standard length – maximum stability for accuracy, finish and productive feed rates
• Full ball nose radius (R = D ÷ 2) – smooth blending on curved and sculptured surfaces
• 2 flute geometry – large chip space for efficient chip evacuation
• 9 sizes – R0.5 to R6 (Ø1 mm to Ø12 mm)
• Plain cylindrical shank – suits collet, shrink-fit and hydraulic holders

Applications

Mould and die making, 3D surfacing, die-sinking, radiused edges and fillets, detail work and general engineering. Suitable for roughing and finishing of contoured surfaces.
