Sada dierových píl KWB 40–230 mm 922920 — vysoký rezací výkon

KWB hole cutter 40–230 mm (model 922920) is a set of high cutting performance hole saws designed to create circular openings in a variety of common building materials. The range covers diameters from 40 mm up to 230 mm, enabling precise large-diameter cuts for installations such as pipes, ventilation ducts and electrical conduits. The tools are engineered for durability and consistent cutting speed across sizes, suitable for both professional tradespeople and experienced DIY users.

Advantages

The KWB hole cutter range delivers consistent cutting performance thanks to hardened cutting edges and a geometry optimized for fast material removal. The saws are built to resist wear during repeated use and to maintain cutting accuracy over time. Compatibility with common arbors and mounting systems makes setup straightforward, while the wide diameter range reduces the need for multiple specialized saws. These features result in efficient, controlled hole cutting in wood, plasterboard and other typical construction materials.

Key specifications

How to use

Select the appropriate diameter from the 40–230 mm range for the required opening and attach the hole cutter securely to a compatible arbor or drill holder. Mark the center point of the hole on the workpiece, position the pilot drill or centering bit, and start drilling at low speed to establish the initial guide. Increase speed and apply steady pressure, allowing the saw teeth to cut without forcing; periodically withdraw the cutter to clear chips if necessary. After cutting, remove the hole cutter and deburr the edge of the opening as needed for a clean finish.

Recommendations

Use suitable personal protective equipment such as safety glasses and gloves, and ensure the workpiece is securely clamped. For best results, match speed and feed to the material being cut and allow the cutter to cool between prolonged cuts to extend tool life.
