Spiral cutting drill bit DeWalt DT70792-QZ for aluminium, plastic, steel, wood

DeWalt DT70792-QZ is a spiral cutting drill bit designed for use with handheld and stationary drills. The geometry of the spiral flute promotes efficient chip evacuation and steady cutting when working with aluminium, plastics, steel and wood. Finished in black and gold, this multi-material bit is intended for general-purpose metalworking, fabrication and woodworking tasks where reliable hole quality and consistent performance are required.

Advantages

The spiral flute design reduces clogging and improves chip removal, supporting cleaner holes and extended cutting life compared with straight-flute bits in mixed materials. Its multi-material capability means one bit can address a variety of jobs without frequent bit changes. The coated finish helps resist wear and makes the bit easier to clean after use.

Suitable for

• Drilling holes in aluminium components and profiles
• Working with a range of plastics including PVC and acrylics
• General steel drilling for light fabrication and fastening
• Wood drilling for cabinetry, frames and joinery

Key specifications

• Drill type: Spiral cutting bit with helical flute geometry
• Compatible materials: Aluminium, plastic, steel, wood
• Finish: Black and gold coating for wear resistance
• Intended use: General-purpose drilling for metalworking, fabrication and woodworking

How to use

Secure the DeWalt DT70792-QZ in the drill chuck ensuring a tight fit, set the appropriate drilling speed for the material (lower speeds for steel, higher speeds for aluminium and plastics) and apply steady pressure. Use cutting fluid or lubricant when drilling steel to reduce heat and wear. For plastics and wood, use moderate speed and avoid excessive pressure to prevent melting or splintering. Retract the bit periodically on deeper holes to clear chips and maintain cooling.

Usage recommendations

Use the correct drill speed and appropriate lubrication for the material to maximise the bit life. Inspect the bit before use for signs of wear and replace when cutting becomes dull to maintain hole quality and operator safety.
