The Procat plate drill set includes three titanium-coated step drill bits in sizes 4-12 mm, 4-20 mm and 4-32 mm. The bits are made from durable 4241 high-speed steel (HSS) and are coated with titanium, which improves heat resistance, reduces friction and significantly extends the life of the bits.
Step drill bits are especially suitable for drilling thin metal sheets, plastics and aluminum surfaces. The stepped structure allows you to make several different hole sizes with the same bit without pre-drilling. The sharpened tip geometry makes the hole start stable and clean without “wandering”.
The three-sided shank improves the stability of the bit in the drill chuck. The set is supplied in a practical case for easy storage and transport.

Intended use:

Sheet metal and electrical installations: Excellent for making electrical panels and cable penetrations in thin sheet metal. The steps allow drilling of multiple sizes without changing the bit.

Plastic covers and junction boxes: The specially titanium-coated blade works cleanly in hard plastic materials. No cracking or melting during drilling.

Installation and HVAC work: The size range of 4–32 mm covers all common pipe and penetration sizes, making the series suitable for the versatile needs of the installer on the jobsite.
