FAQs
What type of drill do I need for this cutter?
You need a lightweight (approx. 2kg) SDS Plus rotary hammer drill with a rotation stop function. It should not be used with standard drills or hammer drills without SDS chucks.
What materials can this cutter be used on?
It is designed for use on blockwork, soft brick, and concrete.
What size hole does the cutter make?
The cutter makes a 77mm round hole, suitable for standard single or double electrical back boxes.
Does this set include the back box?
No, this product is the circular cutter system. The electrical back box itself is not included and must be purchased separately.
Can I use this with any SDS drill?
It requires an SDS Plus chuck, and critically, a rotation stop function. Not all SDS drills have this feature, especially older or very basic models.
How do I maintain the cutter?
Clean off dust and debris after each use and store in a dry place. Inspect the TCT tips for wear and replace if they become significantly blunt or damaged.
Is this suitable for dry lining walls?
No, this cutter is specifically designed for cutting recesses in solid masonry materials like brick and blockwork, not for drywall or plasterboard.
Troubleshooting
Drill not engaging or cutter not spinning.
Ensure the drill is set to the correct mode (hammer drill with rotation, not just hammer-only or rotation-only) and that the SDS shank is fully seated and locked in the chuck.
Slow cutting or excessive heat.
Verify the drill has sufficient power and is set to the correct speed. Check for blockages in the cutter head. Ensure you are using the correct material type (block, soft brick, concrete) for which the cutter is designed. Allow the tool to cool if it overheats.
Cutter binding or getting stuck.
Do not force the cutter. Retract slightly and adjust the angle of entry. Ensure the recess is not obstructed by rebar or very hard aggregate. Use the included chisel to clear obstructions if necessary.
