Marine Step Drill Bits are specialized tools designed for drilling precise, clean holes in metal and other materials, commonly used in marine applications. These bits feature multiple stepped diameters, allowing for hole enlargement without bit changes, enhancing efficiency. Mechanical Systems refer to the integrated components and mechanisms that ensure smooth operation and durability in demanding environments.

Buoyancy: Negative (sinks in water due to metal density)

Material: High-speed steel (HSS), cobalt, or titanium-coated

Point Angle: 118° or 135°

Flute Type: Spiral or straight

Shank Type: Round or hex

Coating: Titanium nitride (TiN) or black oxide

Hardness: 62-65 HRC (Rockwell C scale)

Corrosion Resistance: Moderate to high (depends on coating)

Operating Speed: 500-3000 RPM (varies by size and material)

Application: Metal, wood, and plastic drilling in marine environments
