Ball Nose Double Flute Spiral Bit (DLC Coating)

The Ball Nose Double Flute Spiral Bit is designed for CNC contouring, 3D carving, profiling, and detailed surface machining on suitable materials such as aluminium alloy, copper, acrylic, and similar machinable materials. With a two-flute ball nose design, it is suitable for producing curved surfaces, rounded details, relief carving, and smooth 3D toolpaths.

Made for high-speed CNC machines, engraving machines, rough engraving machines, and machining centers, this cutter combines a 35° helix angle with a fully ground spiral groove for smooth chip removal and stable cutting performance. The DLC aluminium coating improves wear resistance and helps extend tool life during repeated machining work.

Its optimized blade, groove, and core diameter design improves sharpness, chip evacuation, and resistance to tool breakage, making it a practical choice for CNC users who need clean surface quality and efficient material removal.

Ball Nose Cutting Profile

The ball nose tip is designed for smooth curved surfaces and 3D machining applications. It is suitable for relief carving, contour finishing, rounded grooves, surface profiling, and detailed model machining where a flat-end cutter would leave sharper step marks.

This makes the tool useful for decorative machining, mold work, acrylic shaping, aluminium parts, copper engraving, and 3D CNC projects.

Double Flute Spiral Design

The two-flute spiral structure provides a balance between cutting efficiency and surface finish. The optimized 35° helix angle helps guide chips away from the cutting area, supporting smoother cutting and reducing the chance of material buildup.

This is especially useful when machining aluminium alloy, copper, and acrylic, where poor chip removal can affect surface finish and tool life.

DLC Coating for Longer Tool Life

The DLC aluminium coating improves surface wear resistance and helps reduce friction during machining. This supports cleaner cutting, better tool durability, and more stable performance during repeated CNC work.

The coated surface also helps reduce sticking and material buildup when used with proper spindle speed, feed rate, and cutting depth.

Optimized Chip Removal

The cutter features a fully ground spiral groove with improved chip removal space. This allows chips to clear more smoothly from the cutting path, helping reduce heat buildup and improving machining efficiency.

Better chip evacuation also helps lower the risk of tool sticking, rough surfaces, and cutter breakage.

Strong Core Design

The blade, groove, and core diameter ratio is optimized to improve rigidity and vibration resistance. This helps the cutter remain more stable during high-speed machining and reduces the chance of breakage when used with suitable cutting parameters.
