SDS-Plus Square Wall Punch for Type 86 Box Preparation

Prepare a suitable wall recess for an electrical-box installation using a matched power-tool attachment. This square punch is referenced for SDS-Plus systems. It is for competent users checking tool, wall and recess compatibility.

• ✅ Work around a box-shaped recess — The square format provides a defined preparation shape.
• ✅ Use an existing compatible tool — The attachment is referenced for SDS-Plus equipment.
• ✅ Keep the cutting accessory separate — One punch can be selected for a matching job.
• ✅ Check a defined footprint — The stated dimensions help compare the recess.

Confirm the tool mode and wall construction

Check the actual shank, permitted hammer mode and substrate before connecting the attachment. Avoid assuming a square punch operates like a normal rotating drill bit.

The stated size is 14.5 × 8.5 × 4.5 cm. Check for hidden services and use the appropriate installation procedure; no universal concrete or electrical-box fit is promised.
