## Summary description

Stepped HSS-TiN drill bit AWTools AW STEP DRILL BIT HSS-TIN 4–52 mm provides multiple hole diameters in a single tool. Constructed from high-speed steel with titanium nitride (TiN) coating for increased wear resistance and smoother cutting. Designed for drilling sheet metal, thin plates, plastics and laminates; suitable for rapid deburring and enlarging holes without tool changes.

## Long description

AWTools AW STEP DRILL BIT HSS-TIN 4–52 mm is a stepped high-speed steel (HSS) drill specifically designed to produce a range of hole diameters with a single tool. The bit features a titanium nitride (TiN) coating that improves wear resistance and reduces friction during cutting. Its stepped geometry allows progressive drilling and fast hole enlargement in sheet metal, thin plates, plastics and laminates without frequent tool changes.
Advantages
The TiN coating extends tool life and reduces heat buildup for longer continuous use. Stepped design provides multiple diameters in one bit, saving time and minimizing bit changes. High-speed steel construction maintains cutting edge integrity while offering toughness for thin-material applications. The bit produces clean, concentric holes with reduced burr formation and supports rapid deburring and hole-size adjustments.
Suitable for
 Drilling a range of hole sizes in sheet metal and thin steel plates
 Working with plastics, laminates and composite sheets
 Enlarging or reaming existing holes without changing tools
 Rapid prototyping and workshop operations requiring multiple hole diameters
Key specifications
 Material: high-speed steel (HSS) with titanium nitride (TiN) coating
 Diameter range: stepped 4 mm to 52 mm
 Design: multi-step flute geometry for progressive drilling
 Intended materials: sheet metal, thin plates, plastics, laminates
 Typical use: drilling, hole enlargement and deburring in thin materials
How to use
Secure the workpiece to prevent rotation or movement, and select an appropriate drill speed for material thickness and type. Start drilling at the smallest step and apply steady feed pressure; advance progressively through the steps until the desired diameter is reached. Use cutting fluid when machining metals to reduce heat and extend bit life. After use, clean the flutes of chips and store the bit in a dry place to preserve the TiN coating.
Usage recommendations
For best results with sheet metal, clamp the sheet to a backing plate to reduce bending. Use moderate speeds for stainless and hardened thin materials and increase lubrication for tougher alloys. Avoid excessive feed force to prevent step chatter and ensure even hole edges.
