## Long description

DeWalt DT70791-QZ spiral cutting drill bit is designed for drilling aluminium, plastic, steel and wood. The bit features a spiral cutting geometry that promotes efficient chip evacuation and stable drilling performance across a range of materials. It is suitable for use in hand drills and drill presses for general-purpose metalworking, woodworking and plastic fabrication tasks.
Advantages
The spiral cutting geometry improves chip removal and reduces clogging, helping maintain a steady cutting action. Its construction and finish provide improved wear resistance and smoother entry into various materials. The bit is versatile across non-ferrous metals, plastics and common woods, offering consistent hole quality and reduced walking at drill start.
Suitable for
 Drilling holes in aluminium profiles and sheet metal
 Creating holes in plastic panels and components
 General-purpose steel drilling for light to medium tasks
 Woodworking tasks such as dowel and pilot holes
Key specifications
 Cutting geometry: spiral flute for efficient chip evacuation
 Materials: engineered for aluminium, plastic, steel and wood
 Finish: dark and gold-toned surface treatment for wear resistance
 Compatibility: suitable for use in hand-held drills and drill presses
 Intended use: general-purpose metalworking, woodworking and plastic fabrication
How to use
Secure the drill bit firmly in the chuck and set the drill to an appropriate speed for the material being worked: higher speeds for aluminium and plastics, lower speeds for steel. Mark the drilling point and, if necessary, use a centre punch for metal to prevent walking. Apply steady, even pressure and allow the spiral flutes to evacuate chips; withdraw the bit periodically on deeper holes to clear chips and reduce heat build-up. Use cutting fluid for steel to extend tool life.
Usage recommendations
For best results, match drill speed and feed to the material: medium-to-high RPM for aluminium and plastics, low-to-medium RPM with cutting lubricant for steel. Wear appropriate eye and hand protection, clamp workpieces securely, and avoid excessive pressure to prevent overheating and premature wear.
