## Summary description

DeWalt DT70788-QZ is a spiral cutting drill bit designed for drilling in aluminium, plastic, steel and wood. It is intended for use with power drills and offers a spiral flute geometry for efficient chip evacuation and stable cutting. Suitable for general-purpose metal and woodwork, repair tasks and fabrication where versatile material compatibility is required.

## Long description

DeWalt DT70788-QZ spiral cutting drill bit is a multi-material drilling tool designed for use with standard power drills. The bit features a spiral flute geometry that promotes efficient chip evacuation and steady cutting action when working with aluminium, plastics, steel and wood. Built for general-purpose metal and woodwork, repair tasks and light fabrication, this DeWalt spiral drill bit aims to deliver consistent hole quality and reliable performance across a range of common workshop materials.
Advantages
The spiral flute design improves chip removal and reduces clogging during continuous drilling, while the cutting geometry provides stable penetration and reduced walking on the surface. Its construction balances toughness and cutting ability to handle both softer materials like aluminium and plastics and harder materials such as mild steel. The bit's compatibility with standard power drill chucks makes it easy to change and use in handheld or bench-mounted drilling applications.
Suitable for
 Drilling holes in aluminium profiles and sheet metal
 Creating openings in plastic components and panels
 General woodworking tasks including pilot holes and joinery
 Light fabrication and maintenance where mixed-material drilling is required
Key specifications
 Spiral flute geometry for efficient chip evacuation
 Designed for use in aluminium, plastic, steel and wood
 Suitable for standard handheld and bench drills
 General-purpose cutting geometry for mixed-material applications
How to use
Secure the drill bit firmly in the chuck of a compatible power drill and set the drill to an appropriate speed for the material being worked. Use lower speeds for steel and higher speeds for aluminium and plastics, applying steady, moderate pressure while allowing the bit to cut without forcing. Withdraw the bit periodically for chip clearing when drilling deep holes, and ensure workpieces are clamped or supported to prevent movement. If drilling metal, consider using suitable cutting lubricant to prolong bit life and improve hole finish.
Usage recommendations
For best results, match drill speed and feed to the material: reduce speed and increase lubrication when drilling steel, and use higher speeds with controlled feed for aluminium and plastics. Inspect the bit regularly for wear and replace when cutting becomes inefficient or the edges are visibly damaged.
