Overview
Concrete Drill Bit 82 mm with a Depth of 70 mm Thread M22 Cobalt Steel and Tungsten Carbide Teeth Silver For Holes in Walls and Bricks

The drill bit with a diameter of 82 mm is designed for creating clean circular holes in concrete, brick, mixed masonry, and aerated concrete blocks. The working depth of the bit is 70 mm, making it suitable for standard passages for cables, pipes, or boxes in the wall. The body is made of cobalt steel and features a series of tungsten carbide teeth around the circumference, which withstand impacts during hammer drilling. The bit is mounted on a separately sold adapter with an SDS PLUS shank and a centre drill and works with an electric hammer drill. The diameter of 82 mm is suitable, for example, for passing a waste pipe, draining condensate, or routing refrigerant for air conditioning.

At the top of the bit, there is a threaded connection M22, which ensures a secure connection with the adapter and easy replacement of the bit according to the required diameter. The casing has fine grooves around the circumference and a side wall opening, which is clearly visible in the product photographs. The tungsten carbide teeth are welded around the entire circumference of the cutting edge, ensuring that the bit engages evenly and creates a hole with a regular edge. The cutting edge is hardened at high temperatures, which helps it maintain hardness even when working in hard concrete. This makes the bit suitable for craftsmen, plumbers, and DIY enthusiasts who need a reliable tool for wall passages.

  • Type – hollow drill bit for masonry and concrete
  • Diameter – 82 mm
  • Working Depth – 70 mm
  • Connection – M22 thread for adapter with SDS PLUS shank
  • Material – cobalt steel with tungsten carbide teeth
  • Suitable Materials – concrete, bricks, mixed masonry, aerated concrete
  • Usage – passages for air conditioning, pipes, cables, and electrical installation boxes
  • Drive – electric hammer drill via SDS PLUS adapter
  • Contents – 1 drill bit 82 mm without adapter and centre drill

Before drilling, mark the location of the hole and first allow the centre drill of the adapter to penetrate the material to prevent the bit from slipping and to keep the hole precisely in place. Drill smoothly and do not overload the tool; continuously pull the bit out and remove dust and debris from the cut. For thicker walls, it is advisable to drill from both sides towards each other to keep the edge of the hole clean. After finishing work, clean the bit of dust, dry it, and store it in a dry place to keep the thread and teeth in good condition.

The 82 mm bit will enhance the equipment of any workshop where wall passages are drilled. The combination of cobalt steel and tungsten carbide teeth ensures rapid progress in both concrete and bricks. The universal M22 thread allows the use of one adapter for multiple bits of different diameters. The depth of 70 mm covers most standard installation work in flats, family homes, and construction sites. For drilling, simply add an SDS PLUS adapter of a length corresponding to the thickness of the wall.
