SDS Plus drill bits are essential for working with concrete and masonry as they enable quick tool changes and efficient impact energy transfer. Sets like the SDS Plus burgije i dleta Villager Impact Line DCP SET 17 kom combine various lengths and diameters for versatile use on construction sites. This system is the standard for mid-range rotary hammers and ensures durability thanks to reinforced bit heads.
Professional sets cover drill bits ranging from 4mm to 12mm diameter in various lengths, often with included chisels for cutting and channeling. Villager brands offer sets with wear-resistant carbide tips and organizers that simplify transport and storage. Check that the set features diameter markings on each bit for quick identification during work.
Concrete drill bits have carbide inserts and a spiral design for efficient dust removal. Metal drill bits are made from HSS steel (High Speed Steel) with a centered point for precise positioning. Wood drill bits feature a center spur and wide flutes for rapid chip evacuation – never use wood bits on harder materials as they will dull immediately.
Quality is recognizable by precisely ground tips and uniform spirals without visible defects. Cheap sets often contain bits with inconsistent hardness leading to rapid wear. If you work with reinforced concrete, invest extra in bits with reinforced carbide tips that withstand impacts with rebar.
After each use, clean bits with compressed air or a soft brush to remove concrete dust and metal shavings. Periodically lubricate SDS Plus shanks with special grease for easier insertion and removal from the chuck. Store the set in its original case or a compartmentalized box to protect cutting edges from damage during transport.
