The Forstner bit has an excellent lifespan for drilling precision holes. Its tooth-shaped design reduces friction and heat, resulting in increased durability. The short centering tip of the precision drill features two main cutting edges and a peripheral cutting edge (tooth-shaped) for accurate results. The large chip-free zones facilitate optimized chip removal, further enhancing the drill's rapid drilling precision. It allows for smooth, splinter-free drilling of blind holes as well as drilling at edges and slopes, for example, for the attachment of hinges, doweling, or removing knot holes. Suitable for drilling in softwood or hardwood, veneered wood, and non-laminated particle board. It is compatible with all drills with a 10 mm chuck. The 3-sided shank of the Forstner bit prevents slipping in the chuck. It is manufactured according to DIN 7483G, with a cutting hardness of at least 50 HRC. Diameter (D) mm: 40.00, total length (L2) mm: 90, shank diameter (d) mm: 10.
