Supplied as a single unit with an HSS centring drill, the tool is ready for immediate use without a separate mandrel and is packaged in a storage box on card for convenient storage and transport.

Advantages

How to use

Attach the hole saw to a compatible cordless screwdriver according to the tool’s chuck or quick-fit instructions, ensuring the HSS centring drill is correctly seated. Mark the centre point of the hole and position the centring drill before starting the drill at low speed to establish the pilot hole. Increase speed gradually and apply steady, moderate pressure while cutting; avoid excessive force or side-loads that can damage teeth. After cutting, clear swarf and inspect the hole edge; deburr if necessary for a clean finish.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. For metal and steel work, secure the workpiece and use cutting lubricant where applicable to extend cutting life. For drywall and plastics use a lower speed to reduce chipping. Regularly clear chips and check the HSS centring drill for wear; replace when blunt to maintain accurate starts.
