Features and varieties of furniture drill for confirmation

Confirmates became popular in the 90s and still have not lost their relevance in furniture production. These mounts are great for DIY designs. Their correct name is a one-piece screed, and “Confirmat” or Confirmat is the name of a German trade mark that produced hardware of this type.

Experts in Russia have been actively using furniture confirmations since the beginning of the 90s of the last century.

We will tell you which drill bit for furniture screed is suitable for work.

What is a furniture drill for confirmation

The most suitable for installing confirmations are drills that are equipped with a working head. One side of the device makes a hole along the diameter of the neck, and the other countersinks the place where the cap will be located.

 Fasteners
Fasteners can be nails, screws and self-tapping screws.

Types and benefits

For work, ordinary furniture drills and equipped with a stepped mill are used. In the first case, small chips may remain on the surface, which will be covered by the screw head.

The production of durable cabinet furniture largely depends on the use of high-quality materials and fittings.

Drills equipped with a step cutter are more suitable. With their help, you can immediately chamfer for the location of the screw head.

Using such a tool allows you to get a hole of the desired diameter in one go.

furniture assembly
To assemble furniture, you need not only the skills, experience of the master, but also high-quality fasteners.

For your information. The stepped cutter forms a suitable surface for the confirmation head. It does not chip away.

When buying, you need to check the hardness of the drill. It should be 61-64 Rockwell. This value can be found on the product packaging.

Euro screws
Euro screws are installed both on hardwood products and furniture made of laminated chipboard and LMDF.

If it is impossible to see the information (the factory packaging has been lost), then you can see the data that is indicated on the drill body.

On Russian products, a steel grade is indicated. Products made of alloys P18 and P9M5 have the best performance characteristics. On European drills, you need to look for the HSS 4341 marking, which indicates that the product is made of high-speed steel.
