The Innovative Tools 230mm Concrete Puddle Flange Recess Kit is a dual-disc grinder attachment for cutting controlled recesses for standard PVC puddle flanges in concrete slabs. Its concentric 150mm inner disc and 230mm outer disc cut both diameters in a single dry pass, reducing the need for jackhammering and repeated disc changes.
The assembly suits standard 230mm (9 inch) angle grinders with an M14 spindle and uses a 280mm shroud connected to a suitable construction dust extractor. It is intended for new or cured concrete wet-area floors, including bathrooms, laundries, balconies, podiums and commercial amenities, and is not suitable for FC sheeting or wet cutting.
Set the recess depth to suit the selected flange, test-fit it flush with the slab and remove residual dust before bonding and waterproofing.
- Dual concentric diamond discs form the 150mm and 230mm recess diameters simultaneously.
- 280mm dust shroud connects to suitable construction vacuum extraction.
- M14 mounting suits a standard 230mm (9 inch) angle grinder.
- Designed for dry recessing in new or cured concrete slabs only.
- Compatible with standard PVC puddle flanges, including the Allproof Leak Control flange.
- Typical consumable disc life is approximately 7 to 15 recesses, depending on concrete hardness, aggregate and operator technique.
- Available as a kit only or bundled with a Makita 230mm grinder.
- Recessing standard PVC puddle flanges into new or cured concrete slabs.
- Bathroom, ensuite, laundry and commercial amenity drainage penetrations.
- Balcony and podium slabs where the selected drainage flange must finish flush with the concrete.
- Retrofit and rectification work in existing concrete floors.
- Repeated commercial recessing where controlled diameter and depth are required.
