How to Make a Hole in a Saw

Typically, sinks have a hole for installing the mixer. But there are stainless steel models in which there is no groove. The way out is to make a hole of the desired diameter yourself. How to make a hole for the mixer in a stainless steel sink.

How to Make a Hole in a Saw

Reasons for lack of holes

Manufacturers of sinks and plumbing fixtures are trying to standardize the dimensional parameters of the models so that they are as compatible as possible with each other. But there is one important circumstance: individual layouts are very popular both in the kitchen and in the bathroom. To satisfy such needs, it is necessary to produce washing models in which a hole for the mixer is not provided. The groove is done independently in the most convenient place and with the necessary characteristics.

There are no openings in metal sinks with two bowls, where, by default, grooves for washing or drying are not provided for practical reasons. A person chooses the best option for himself, installing the sink in place.

The size of the holes depends on the design of the crane. Mixer models may vary significantly. The size of the required groove in the sink depends on this.

It matters: the location of the hot and cold water supply tubes, the design of the fastening mechanisms.

Before doing work, you need to choose a model, find out its parameters and design features.

Preparatory Activities

Before you cut a hole, you need to thoroughly prepare. First make measurements. The groove should have a diameter so that the mixer can easily pass during installation. There should also be no problems with fixing the crane. The measured diameter is applied at the drilling site. It is important to measure everything, because the error will be worth a lot.

After applying the marking at the groove, you need to prepare the workspace and tool. The place where the work will be carried out should be free and spacious. The sink should be stable and reliable. All unnecessary needs to be removed.

The hole for the mixer in the stainless steel sink is drilled with a drill and various nozzles. Tools that will be required to drill a hole in the sink for the faucet.

  1. Drill.
  2. File, file, skin.
  3. A small file or cutter for metal.
  4. Protective glasses.
  5. Brush.
  6. Water for cooling.

Drilling nozzles with which you can make a hole:

  1. conventional drill bit for metal (preferably with diamond coating);
  2. herringbone cone drill;
  3. bimetallic circular saw type of crown;
  4. drill joint drill with a diameter of 28, 30, 32 or 35 mm (the size depends on the parameters of the mixer).


The methods by which grooves can be made in a sink depend on the specific tool. You need some kind of drilling nozzle for a drill. The most affordable way is to make holes with an ordinary drill bit for small diameter metal: 6, 8, 10 mm.


  1. By marking the circumference, several grooves are made along the perimeter.
  2. Water is cooled periodically. Drilling is carried out at low speeds.
  3. The grooves are connected using a metal file or file.
  4. The edges of the holes are processed and aligned with a file, file and sandpaper.

How to cut a hole in the sink under the mixer using a bimetallic circular saw.

The method using crowns is used for mass hole making in sinks. One with periodic cooling is enough for drilling 1015 grooves. Without cooling, the hole saw will fail after 23 holes.

In a similar way, grooves can be drilled using a herringbone or a drill joint. After making a groove, the edges are processed. To do this, use a file, file, skin.
