## Summary description

AWTools spiral step drill bit M2-TiAlN with a 4–12 mm step range. Designed for stepped drilling to create holes of varying diameters in sheet materials and thin metals. Made from M2 high-speed steel with TiAlN coating for increased surface hardness and heat resistance. Ideal for installers and workshop use where multiple hole sizes are required without tool changes.

## Long description

AWTools spiral step drill bit M2-TiAlN 4–12 mm is a single-flute stepped drill designed for drilling multiple hole diameters in sheet materials and thin metals without changing tools. Manufactured from M2 high-speed steel and finished with a TiAlN (titanium aluminium nitride) coating, the bit provides increased surface hardness and improved resistance to heat and wear during repeated cutting operations. The 4–12 mm step range covers common hole sizes used in installation and workshop tasks, enabling fast stepwise enlargement of pilot holes or direct stepped drilling from thin gauges.
Advantages
The TiAlN coating reduces friction and extends tool life under higher temperatures, while the M2 high-speed steel core maintains cutting edge strength and toughness. The spiral step geometry offers efficient chip evacuation and smoother cutting action compared with straight-step designs, which helps maintain hole quality and accuracy. A single tool covers multiple diameters, reducing tool changes and setup time for repetitive work on metal sheets and similar materials.
Suitable for
 Drilling stepped holes in sheet metal and thin steel or aluminum panels
 Installing fasteners where multiple hole diameters are required
 Workshop and maintenance tasks requiring rapid diameter changes without tool swaps
 Preparing pilot holes and enlarging holes in electrical, HVAC and metal fabrication work
Key specifications
 Step diameter range: 4–12 mm (progressive stepped diameters)
 Material: M2 high-speed steel
 Coating: TiAlN (titanium aluminium nitride) for increased hardness and heat resistance
 Geometry: spiral (single-flute stepped) for improved chip removal
 Intended materials: sheet metals, thin steel, aluminum and similar alloys
How to use
Secure the workpiece and select an appropriate drilling speed based on the material thickness and hardness; lower speeds are recommended for harder metals to avoid overheating. Start with a pilot mark or center punch to prevent walking, align the spiral step drill bit in a drill press or hand drill, and apply steady, moderate feed pressure while allowing the bit to cut progressively through the steps. Withdraw occasionally to clear chips if drilling thicker sections or when chip accumulation is visible. Use cutting fluid on ferrous materials to reduce heat and extend tool life.
Usage recommendations
For best results, use the drill bit with a secure chuck and maintain correct concentricity. Select cutting speeds appropriate for the work material, and apply coolant when drilling steel to preserve the TiAlN coating and cutting edge. Replace the bit once wear or damage affects hole quality.
