How to Create Draining Grooves in Worktop - Kitchen Fitting Tools
A popular request from customers is to have draining grooves routed into the new worktop being fitted in their kitchen. Not only is it practical, but it can also look fantastic. If you do it right!
We visited our pals Couple 'a Tools on the day they were creating a sink aperture in Apollo Slab Tech worktop. The customer also requested draining grooves to be routed into the worktop and for the edges to have a delicate 45º chamfer.
Choose the Best Draining Groove Jig
Gus at Couple 'a Tools has always used the Trend draining groove jig when he fits kitchens. So, we took along the EDGJIG from EDGE Professional Tools as we knew it has better specifications and features. Yes, really.
For example, to prevent the jig bowing while your router cuts the grooves in the worktop, the EDGJIG has grub screws which you adjust until they make contact with the surface of the worktop. No bowing while you rout, and they make sure the grooves have a constant 5º fall. This way the grooves will ensure the drained water gently flows into the sink.
It's a true no-brainer feature, and no other draining groove jig on the market has it.
You'd think someone would have thought of this before...
Needless to say, Gus was well impressed.
Ask the Customer What They Want
Before making the cuts for the draining grooves, the guys made two separate grooves in a piece of off-cut worktop. The grooves were different depths. Why did they do this? To allow the customer to choose the final look. And the customer went for the deeper groove. Job done.
Now it's time to set up the EDGJIG and to choose the correct router cutter.
Setting Up the EDGJIG for Draining Grooves in Worktop
The set up of the EDGJIG is simple. Place it on the worktop, with the clearly marked "SINK" end facing the sink aperture.
The grooves are at a 50mm pitch and are 450mm long. There are 3 removable slopping runners for support, a hole to check your cutter diameter before commencing work and fixing holes for user-made stops for repetitive work if required.
Gus simply clamped the EDGJIG in place and got to work setting the depth on the cutter.
Choose the Correct Cutter for the Draining Grooves
We brought the Couple 'a Tools team the DIMAR-made 5mm radius cutter from EDGE Professional Tools (part number 1063404).
Again, Gus commented that he normally uses cheaper cutters for this job, but noted after routing out the grooves that the 1063404 from EDGE Pro Tools was smoother and faster.
Once the depth of plunge on the router was set, it was time to rout the grooves in the Apollo Slab Tech worktop. Make sure you're using adequate PPE and dust extraction while doing this!
How to Chamfer Kitchen Worktop
As the customer wanted the facing edge of the Apollo Slab Tech worktop to have a small chamfer, we brought Gus the 27mm Rota-Edge Bearing Guided Roundover Cutter by EDGE Professional Tools (part number 1024524).
Not only does this have one of the smoothest ball bearing guides on the market, but the tungsten carbide blades are also removable. This means they can be sharpened using a diamond sharpening credit card stone and original formula lapping fluid, but they can also be replaced when you need it.
Yes, it costs a little more, but you get way more value for money over time.
I'll be brutally honest, with being a Trend user for the best part of 20 years, these router cutters are as good as, if not better than Trend. Very well made, super-smooth ball bearings. I'd be happy to switch my whole set up across without a worry. It can be an expensive mistake when cutting worktop!
With the draining grooves routed, the chamfered edge...chamfered, it was time to fit the massive piece of Apollo Slab Tech worktop in place, which meant it was time for us to pack up and leave the guys to it!
