Check it suits your setup
Two minutes here saves a return. This kit is purpose-built for FC sheeting and 230mm puddle flanges - confirm your grinder and substrate before you buy.
Stop recessing puddle flanges the slow way
One setup. One pass. Done.
Locate the tool over your installed 100mm pipe, mount up, connect the vac - then cut and recess in a single pass.
Fit the disc to a 230mm / 9-inch M14 grinder and connect the dust shroud to your vacuum.
The wheel bearing locks onto your installed 100mm pipe to centre the tool; lower it to cut the 150mm clearance hole and grind the 230mm recess to depth in one pass.
Lift the tool, clear the recess and drop your 230mm puddle flange into a consistent, flange-ready seat.
How fast does it pay for itself?
Drag the sliders to match your work. Most tradies make the kit back within the first couple of weeks.
Estimates only, based on your inputs. Actual time and savings vary by site, operator and conditions.
FC kit vs the old method
Built for cleaner FC sheet grinding
FC sheeting can create hazardous silica dust when cut, drilled or ground. The custom dust shroud connects to vacuum extraction to help capture dust at the source while you recess - an on-tool dust control measure.
Technical specifications
What's included
Segmented diamond tip that grinds the recess to a consistent depth.
Pre-attached to the disc centre - rides on your installed 100mm pipe to hold centre.
Connects to your vacuum to help capture dust at the source.
Replace the disc, not the whole kit
Once the disc reaches the end of its life (around 100 recesses), just swap the diamond disc and keep using your wheel bearing and dust shroud.
Built for repeated wet-area prep
Recess the flange cleanly before membrane and tiling.
Centre on the installed 100mm pipe, cut and seat the flange in one setup.
Fast, consistent recesses on internal FC sheet floors.
Purpose-built for compressed fibre cement flooring.
Where the time saved per recess really adds up.
Standardise recess depth across the whole crew.
Complete the setup
Add the consumables and PPE that finish the job. Tick what you need and add them in one go.

Frequently asked questions
-
Will this work with my grinder?
Yes - it fits any standard 230mm (9-inch) angle grinder with an M14 thread, which covers Makita, DeWalt, Metabo, Bosch, Milwaukee and most major brands. If you don't own a 9-inch grinder, choose the With Grinder option.
-
Does it work on concrete or just FC sheeting?
This kit is purpose-built for FC sheeting (compressed fibre cement) and won't perform on concrete. For concrete, use the dedicated concrete recess kit - call us and we'll point you to the right tool.
-
What size puddle flange is it for?
It's designed for standard PVC puddle flanges that seat in a 230mm recess over a 100mm pipe - the standard used in most Australian wet-area construction.
-
Is the grinder included?
Only if you choose the With Grinder bundle, which includes a 9-inch grinder. The standard Kit Only option does not include a grinder.
-
Do I need a pilot hole, or does the pipe need to be in first?
No pilot hole needed. This kit is made for FC sheeting where the 100mm pipe is already installed - the integrated wheel bearing drops onto that pipe and centres the tool for you, then cuts the 150mm clearance hole and grinds the 230mm recess in one pass.
-
How many recesses will one disc do?
Approximately 100 recesses per disc under normal use on FC sheeting - roughly $4.59 per recess. Replacement discs are available separately.
-
Can I buy replacement discs?
Yes. Replacement discs are available separately, so you only replace the consumable disc - not the whole kit, wheel bearing or dust shroud.
-
Is it dust-free?
It's dust-controlled, not dust-free. The custom 280mm shroud and 290mm dust ring connect to a suitable vacuum to help capture FC dust at the source. PPE is still required and silica dust controls still apply - always follow your site's WHS requirements.
-
Can I use it on Scyon board or particleboard?
It's engineered and calibrated for compressed fibre cement (FC) sheeting. The depth guide and cutting dimensions are set for FC sheeting puddle-flange installs, so for best results stick to FC sheeting.
-
How quickly does it pay for itself?
For most tradies doing regular FC sheet wet-area prep, the kit pays for itself within the first couple of weeks. At around 10 recesses a week you save roughly 20-25 minutes of labour per recess versus the old method - use the calculator on this page to plug in your own rate and volume.
