Overview
Large Diameter Drill Bit 150 mm Depth 70 mm Thread M22 Cobalt Steel with Carbide Teeth Silver For Passages in Walls and Concrete

The drill bit with a diameter of 150 mm is designed for drilling large circular passages into concrete, brick walls, mixed masonry, and aerated concrete. With a working depth of 70 mm, it is capable of creating passages for ventilation, extractor hoods, fans, or larger diameter pipes. The body of the bit is made of cobalt steel, and the cutting edge is fitted with carbide teeth that withstand stress during hammer drilling. The bit screws onto an adapter with an SDS PLUS shank and a centre drill, which is sold separately. It is powered by an electric hammer drill, making it suitable for demanding tasks during renovation and construction.

The upper part of the bit features a thread M22 for a secure connection with the adapter, allowing for quick changes to other diameters in the same range. The casing has grooves around the perimeter, and there is a hole on the side, as shown in the product photographs. The carbide teeth are distributed around the entire perimeter of the cutting edge, and the edge is hardened at high temperatures to maintain hardness even during prolonged work in hard materials. The large diameter of the bit is especially appreciated by plumbers, heating engineers, and DIY enthusiasts who need to create a precise passage instead of laboriously chiselling a hole.

  • Type – hollow drill bit of large diameter for masonry
  • Diameter – 150 mm
  • Working Depth – 70 mm
  • Connection – thread M22 for adapter with SDS PLUS shank
  • Material – cobalt steel, carbide teeth
  • Suitable Materials – concrete, bricks, mixed masonry, aerated concrete
  • Usage – passages for ventilation, extractor hoods, fans, and wider pipes
  • Drive – electric hammer drill via SDS PLUS adapter
  • Package Contents – 1 drill bit 150 mm without adapter and centre drill

First, mark the centre of the future passage and start drilling with the centre drill of the adapter, which guides the bit and prevents it from slipping on the surface. When drilling a large diameter, work with less pressure and give the tool time; occasionally retract the bit and clean the cut of dust. It is advantageous to drill a thick wall from both sides to keep the edges of the passage clean and without chipping. After use, clean the bit and the thread of dust and store it in a dry place.

The 150 mm bit is a practical helper wherever a large circular hole needs to be created in a wall. The combination of carbide teeth and a sturdy steel body allows for drilling into both concrete and bricks without chiselling. The M22 thread allows the same adapter to be used for bits of different diameters. The depth of 70 mm is sufficient for most passages in partitions and external walls when drilling from both sides. To work, simply add an adapter with an SDS PLUS shank and a hammer drill.
