Step Drill Bit (Stufenbohrer): Precision engineered to improve stability and reliability. High speed steel (HSS) construction for durable metal drilling performance. Woodworking Set (Holzbearbeitungsset): Easy handling of large pieces of firewood or wood at home. Facilitates work and saves energy and time by splitting wood with the wood drill. Steel Drill (Bohrer fuer Stahl): Geometry reduces friction and speeds up drilling. Simple to mount in your drill or magnetic drill press. Compatible with most magnetic drill presses. Cone Drill Bit (Kegelbohrer): Made of steel for high strength. Exceptional stiffness, impact resistance, and wear resistance. Durable; designed as a step cone drill bit. Use scenarios: - Fabrication and maintenance: drill through steel using a magnetic drill press for precise holes with reduced tool wear. - Home woodworking: split large firewood or wood pieces efficiently using the wood drill as part of the woodworking set. - General metalworking: perform durable, high-precision drilling on hard materials with the cone and step drill bits, benefiting from reduced friction and reliable performance.
