If you're building a new home or remodeling your kitchen, you must cut kitchen worktops for appliances such as stoves, surface units and sinks. There are several methods you may use to do this. A skill saw or a jig saw are the two best options. You may use a router in some cases.
Cut kitchen worktops by first measuring your sink size. If your sink is a standard double-bowl, it's normally 82.5 by 55 cm (33 by 22 inches). This is the overall width of the sink. So, your cut-out must be 80.6 by 53.1 cm (32 1/4 by 21 1/4 inches). This gives you adequate area for your sink to set on top of your counter worktop. You must cut small radii on the four corners.
Use a skill saw to cut kitchen worktops. Cut from the bottom of your worktop. Cut your straight cuts with your skill saw. After you make your straight cuts, use two nails and nail one on each end of your sink cut-out. This holds up your sink cut-out so it won't chip your plastic when you finish your cut-out. Now, use a jig saw to finish your small radius cuts on all four corners.
Make a kitchen sink cut-out from the top of the counter once you've set your worktops in place. Use masking tape to lay out your sink hole. On some worktops, you can't see your mark. Masking tape also helps prevent chips and damage to the plastic of your worktops.
Choose a jig saw for this cut if you're not comfortable using a skill saw. Drill a pilot hole on the inside of your mark so that you may start your cut with your jig saw. Make sure you stay on the inside of your line, keeping pressure down on your jig saw as you make your sink cut-out when you cut kitchen worktops.
