## Summary description

Spiral step drill bit by AWTools with M2 high-speed steel substrate and TiAlN coating, designed for drilling hole sizes from 4 to 32 mm. The stepped geometry and spiral flutes enable progressive hole enlargement in sheet metal and thin materials, reducing tool changes. Suitable for hand drills and drill presses for fast roughing, deburring and enlarging pre-existing holes.

## Long description

Spiral Step Drill Bit AWTools M2-TiAlN 4–32 mm, single piece is a stepped twist drill designed for progressive enlargement of holes in sheet metal and other thin materials. Constructed from M2 high-speed steel and finished with a TiAlN (titanium aluminum nitride) coating, the bit combines hardness and heat resistance for extended cutting life. The spiral flutes and stepped geometry allow drilling of multiple hole diameters with one tool, reducing tool changes when working with thin-walled parts or when deburring and enlarging pre-existing holes.
Advantages
The M2 substrate provides wear resistance and toughness while the TiAlN coating improves thermal stability and reduces friction during high-speed drilling. Spiral flutes evacuate chips efficiently, helping to maintain cutting performance and reduce clogging. The stepped design enables sequential hole enlargement without the need for pilot drills or multiple individual bits, which saves time and simplifies workflow. The single-piece construction ensures consistent concentricity and reliable alignment when used in hand drills or drill presses.
Suitable for
 Drilling and enlarging holes in sheet metal (steel, stainless steel, aluminum thin sheets)
 Deburring and finishing existing holes in thin materials
 Workshop use with hand drills and drill presses for fast roughing operations
 Applications where multiple hole sizes are required without frequent tool changes
Key specifications
 Material: M2 high-speed steel substrate
 Coating: TiAlN (titanium aluminum nitride)
 Diameter range (stepped): 4 mm to 32 mm
 Geometry: stepped profile with spiral flutes
 Construction: single-piece design for concentricity
 Suitable machines: hand drills and drill presses
How to use
Secure the workpiece and mark the desired starting position. Use appropriate clamping to prevent movement. Install the spiral step drill bit in a properly rated chuck and ensure it is tightened concentrically. Start drilling at low to moderate speed, applying steady axial pressure; the TiAlN coating allows higher speeds than uncoated HSS in many cases, but avoid excessive feed that could overload the step. Periodically withdraw the bit to clear chips from the flutes and to check hole size. For best results when enlarging pre-existing holes, guide the step progressively along the steps until the required diameter is reached.
Usage recommendations
Use cutting fluid or appropriate lubricant when drilling steel or stainless steel to extend tool life and improve chip evacuation. For aluminum and non-ferrous metals, reduced lubrication or air cooling may be sufficient to prevent chip buildup. Match drill speed and feed to material thickness and hardness: lower speeds for hard stainless steel, higher speeds for softer materials. Inspect the cutting edges periodically and replace the bit when wear degrades hole quality or increases torque.
