Cut Out a Rectangular Sink
Step-by-step instructions and list of necessary tools for cutting out a rectangular sink.
- Core the corners with a wet core drill bit (most common core bit size is 1-3/8" - can use with the Alpha® VSP-320 or other appropriate machine.)
- Then cut the straight sections with the AccuGlide.
- Use a Jig Saw and diamond blade (or angle grinder and 4.5" straight diamond blade) for finishing the tag left behind by the circular saw blade. Always use GFCI protection.
- Clean up/true the inside corners using a plug stone in 60 and 120 grit (silicon carbide stone in a 1 3/8" – 2” diameter) on the VSP-320 (maximum RPM) or on your high speed angle grinder.
- Use the Alpha® Profiler B to profile the top edge if needed.
- Many fabricators will polish the under-mount sinks with 4" diamond polishing pads and 3" flexible backer pad. This set up allows for polishing straight runs but also has extra flex for the inside corner.
- Use a plastic coring template with a 1-3/8” core bit to drill your faucet holes.
