The range of core drill bits comprises advanced technical solutions designed to produce high-precision circular holes in construction and installation projects. This professional range is highly effective at tackling dry or wet drilling challenges in demanding materials such as concrete, masonry, sheet metal and ceramic tiles.

Drilling efficiency and alloys in the Core Drill Bits series

This technical series stands out for incorporating high-toughness bimetallic constructions and state-of-the-art tungsten carbide or continuous diamond cutting edges. Their cylindrical geometry is designed to reduce friction during rotation, allowing for extremely smooth chip and dust evacuation, which prevents premature overheating of the tool.

The structural robustness of each core bit ensures perfectly calibrated drill holes without cracking the material or deforming the entry edges on the workpiece. As they are fully compatible with quick-change mechanical systems, these tools optimise the working time of professional fitters in plumbing, electrical and HVAC tasks.

Range of diameters and formats from manufacturers Bosch and Rubi

Backed by leading industry names such as Bosch and Rubi, the collection offers a wide range of diameters to suit every need. The range includes Progressor bi-metal saw blades for metal or wood, carbide drill bits for ceramics, and SDS-Plus and SDS-MAX hollow core drill bits for concrete.

A variety of products available in the core bit catalogue

• Bosch Progressor bi-metal core bit saws in diameters ranging from 17 mm to 102 mm.
• Rubi tungsten carbide drill bits in sizes of 35 mm and 45 mm for tiling.
• Specialised Bosch bi-metal core drills in 24 mm, 27 mm and 35 mm.
• Bosch SDS-PLUS hollow core drill bits for concrete work, from 40 mm to 68 mm.
• Bosch SDS-MAX and GBH HBK hollow drill bits for deep drilling from 50 mm to 150 mm.

Advantages of drilling with bimetallic and carbide core bits

Equipping your machinery with this range of circular core bits ensures superior performance and maximum precision for every hole drilled on site. You’ll achieve a clean, professional finish and have the peace of mind that comes with tools built to withstand intensive use.
