## Summary description

AWTools step twist drill bit M2-TiAlN (model 1077254) is a stepped drill designed for producing holes of increasing diameters within a single tool, covering a range of 4–22 mm. Constructed from M2 high-speed steel and finished with TiAlN coating for improved wear and heat resistance. Suitable for drilling in metals and general workshop applications where multiple hole sizes are required without tool changes.

## Long description

AWTools step twist drill bit M2-TiAlN coating, step range 4–22 mm, model 1077254 is a stepped drill designed to create a series of hole diameters with a single tool. Made from M2 high-speed steel and finished with a titanium aluminum nitride (TiAlN) coating, this step drill delivers improved wear resistance and higher heat tolerance compared to uncoated HSS. The stepped geometry lets a single pass form progressively larger holes from 4 mm up to 22 mm, reducing tool changes and setup time in workshop and metalworking tasks.
Advantages
The M2 substrate provides good core strength and toughness for general workshop use, while the TiAlN coating increases surface hardness and thermal stability during drilling operations. The stepped design enables consecutive hole sizes in one operation, improving efficiency when multiple diameters are required. Optimized flute geometry helps evacuate chips and maintain hole quality across the step transitions.
Suitable for
 Drilling progressively larger holes in sheet metal and thin plates
 Workshop and maintenance tasks where multiple diameters are needed without tool changes
 Prototyping and small-series production in metalworking
 Drilling in common ferrous and non-ferrous metals compatible with HSS-TiAlN tools
Key specifications
 Material: M2 high-speed steel with TiAlN surface coating
 Step range: 4 mm to 22 mm
 Design: stepped twist drill geometry for sequential hole sizes
 Coating benefits: increased wear resistance and improved heat resistance
 Application type: general metalworking and workshop drilling
How to use
Secure the workpiece and select appropriate clamping to prevent movement. Use a drill press or a handheld drill with stable speed control. Start at the recommended speed for HSS-TiAlN tools on the material being drilled, apply steady feed pressure and allow the drill to penetrate each step fully before advancing to the next. Periodically withdraw the drill to clear chips and reduce heat build-up. Use cutting fluid when drilling tougher alloys or for prolonged operations to extend tool life and improve hole finish.
Usage recommendations
Begin at lower spindle speeds for larger diameter steps and increase speed moderately for smaller steps, following material-appropriate cutting speed guidelines. Keep steady feed and ensure chip evacuation; replace or regrind the tool when edge wear affects hole quality.
