Sutton 30 x 180mm Ball Nose Slot Drill 2 Flute - 8% Cobalt Long

Sutton Tools is an Australian-owned manufacturer of precision cutting tools and threading accessories, supplying tradespeople, engineers, and manufacturing operations across Australia and internationally. Their product range spans taps, dies, drills, endmills, holesaws, and related tooling — all engineered to perform consistently under real industrial conditions. AIMS Industrial supplies the Sutton Tools range to Australian businesses as part of our commitment to stocking quality, trusted brands.

Sutton ball nose endmills produce 3D contoured surfaces in CNC milling operations — their hemispherical tip traces surface profiles precisely and is the standard tooling choice for mould, die, and sculptured-surface machining.

Where this product is used

Used for 3D profiling, contouring, and fillet milling on CNC machining centres in mould, die, and precision engineering applications.

• 3D surface machining of moulds, dies, and sculptured components where the ball nose radius traces complex surface profiles during multi-axis CNC operations.
• Producing radii and blends in corners and pockets where a flat-bottom endmill cannot reach the required surface geometry.
• Finishing passes on hardened steel surfaces in toolroom environments, leaving a smooth scalloped finish for subsequent polishing.

Key specifications

Selecting the right option

Ball nose endmills are rated by ball radius (half the diameter) — confirm the minimum corner radius your design requires before selecting size. Use as many passes as needed at light step-down to achieve the required surface finish. Choose cobalt for steel roughing; solid carbide for hard milling and high-speed finishing.
