Drill bit DeWalt DT9597-QZ, 20 mm diameter, single piece

DeWalt DT9597-QZ single drill bit with a 20 mm diameter is a large-diameter accessory intended for general drilling tasks. The bit is supplied as a single piece and is designed for use with compatible hand-held or bench drills. It is suitable for creating sizable holes in materials commonly encountered in construction and workshop environments when matched with the correct drill type and speed.

Advantages

The 20 mm diameter provides efficient removal of material for faster hole creation compared with smaller bits. Manufactured by a recognised brand, the drill bit is made to standard geometry suitable for reliable centring and cutting under typical drilling conditions. Supplied as an individual item, it is simple to store and replace when needed.

Suitable for

• Drilling large holes in wood with appropriate drill settings
• Drilling into soft metals or metal sheets when used with suitable drill and speed
• General construction and installation tasks requiring a 20 mm bore
• Workshop applications where a single, large-diameter bit is required

Key specifications

• Diameter: 20 mm
• Quantity: single piece
• Intended use: compatible with hand-held and bench drills
• Packaging dimensions (for storage/transport): 450 × 350 × 150 mm
• Suitable for materials: wood, metal sheets, general construction materials (depending on drill and operating parameters)

How to use

Select a drill with compatible chuck capacity and secure the 20 mm bit firmly in the chuck. Set the drill speed and feed according to the material being drilled: lower speeds for metals and higher speeds for softwoods, while applying steady axial pressure. Use appropriate clamps or supports to secure the workpiece and wear appropriate personal protective equipment. Periodically withdraw the bit to clear chips and avoid overheating.

Usage recommendations

For optimal results, confirm chuck capacity and use a pilot hole when precise centring is required. Match drill speed to material hardness, apply lubrication for metal drilling, and allow cooling pauses to prolong bit life.
