## Summary description

DeWalt DT5031-QZ is a single-piece step drill bit supplied as 1 pc. Designed as a step drill bit for drilling progressively larger holes in thin materials such as metal and sheet, it suits applications in metalworking, electrical installation and HVAC where tapered hole sizes are needed. Compact format for use with standard drills and drill drivers.

## Long description

DeWalt DT5031-QZ is a single-piece step drill bit supplied as one unit, designed for drilling and enlarging holes in thin materials. It drills progressively from 4 mm up to 34 mm in a single tool, making it suitable for metalworking, electrical installation and HVAC tasks where tapered or stepped holes are required. The compact format fits standard drills and drill drivers and is intended for use with construction steel, ferrous and non-ferrous metals, plastics and other thin-walled materials up to 3 mm.
Advantages
The bit features optimized geometry that reduces walking and improves penetration speed, resulting in accurate hole sizes with fewer pilot operations. A titanium coating increases wear and corrosion resistance, extending tool life compared with standard black oxide finishes. Being a single-piece step design, it offers convenient step-by-step hole enlargement without tool changes and provides a range of hole diameters in one compact cutter.
Suitable for
 Drilling stepped holes in sheet metal and thin-walled panels
 Creating cable and conduit entry points in electrical installation
 Enlarging pre-drilled holes in HVAC ducts and fittings
 Working with construction steel, aluminium, copper and plastics up to 3 mm thick
Key specifications
 Drilling range: 4 mm to 34 mm in progressive steps
 Single-piece step drill design for progressive hole sizing
 Suitable material thickness: up to 3 mm for thin-walled materials
 Optimized flute and cutting geometry to reduce walking and improve feed
 Titanium surface coating for enhanced wear and corrosion resistance
 Compact shank compatible with standard drill chucks and drivers
How to use
Secure the step drill bit in the drill chuck ensuring firm clamping. Mark the drilling position and, if necessary, use a center punch to start the hole. Operate the drill at an appropriate speed for the material—lower speeds for ferrous metals and higher speeds for aluminium and plastics. Apply steady, moderate pressure and allow the bit to cut progressively through the material to the required step diameter. Withdraw the bit occasionally to clear chips and reduce heat build-up. After use, clean the bit and store it in a dry place to preserve the coating.
Usage recommendations
Use cutting lubricant when drilling harder metals to extend tool life and improve finish. Start with a pilot point or low-speed alignment to prevent walking on smooth surfaces. Avoid excessive feed force; let the optimized geometry and coating do the cutting to achieve accurate stepped holes.
