## Long description

AWTools Spiral Step Drill Bit M2-TiAlN 6–35 mm is a stepped drill designed for progressive drilling of sheet materials and thin metals. Constructed from M2 high-speed steel and finished with a TiAlN (titanium aluminum nitride) coating, this tool provides an extended tool life and improved heat resistance compared with uncoated HSS. The spiral stepped profile allows drilling a sequence of hole diameters with a single bit, eliminating frequent tool changes during installation and sheet-metal work. The bit is compatible with hand drills and drill presses and is intended for use where multiple hole sizes are required in thin materials.
Advantages
The TiAlN coating increases surface hardness and provides better thermal stability during high-speed drilling, reducing wear and extending service intervals. The M2 HSS core ensures good toughness and cutting performance in thin ferrous and non-ferrous metals. The spiral flute geometry improves chip evacuation and reduces clogging when cutting sheet materials. The stepped design delivers consistent hole diameters across the range from 6 mm up to 35 mm without the need to change bits.
Suitable for
Drilling holes in sheet metal and thin steel plates
HVAC installations (duct and flange penetrations)
Electrical and plumbing fitting openings
Prototype and maintenance work requiring multiple hole sizes
Key specifications
Material: M2 high-speed steel (HSS)
Coating: TiAlN (titanium aluminum nitride)
Cutting range: stepped diameters from 6 mm to 35 mm
Geometry: spiral flutes with stepped cutting profile
Intended material thickness: sheet materials and thin metals
Compatibility: suitable for hand drills and drill presses
How to use
Secure the workpiece and mark the required hole center. Use appropriate personal protective equipment and clamp thin sheets to prevent vibration. Fit the spiral step drill into the drill chuck, ensure concentricity, and select a moderate drilling speed suitable for the material and diameter being cut. Use steady feed pressure, allowing the bit to cut progressively through each step. Clear chips periodically for best performance. Apply cutting lubricant when drilling stainless steel or other heat-sensitive alloys to reduce friction and extend tool life.
Usage recommendations
For best results, start at lower speeds for larger step diameters and increase speed for smaller steps. Use cutting fluid on stainless steel and harder alloys; for general mild steel and aluminium, light lubrication or dry cutting is acceptable. Replace the bit if grinding wear or chipping affects hole quality.
