Lasts up to 3 times longer than a standard Bosch Forstner bit. - Forstner bits are excellent accessories for creating larger holes in wood. However, not all Forstner bits will allow you to drill clean holes in smooth surfaces. The EXPERT wood bit has been designed to guarantee you perfectly clean and splinter-free blind holes in all types of wood. We have designed the wavy cutting edge of the EXPERT wood bit using Bosch's Tip Technology to provide professionals with exceptionally precise and durable Forstner bits, suitable for both hardwood and softwood. The wavy edge with sharp serrations combines the advantages of a continuous cutting edge and a saw-tooth edge: it drills clean and splinter-free holes when you need it, without overheating. The EXPERT Forstner wood bit will allow you to carry out your work easily and safely, whether it is drilling clean and splinter-free blind holes for hinges, counterbores, or any other woodworking element. Its solid and sharpened wavy edge, designed using Bosch's Tip Technology, guarantees its efficiency and longevity in both hardwood and softwood. The 3-flat shank prevents slipping in the chucks of rotary drills and screwdrivers. Lasts up to 3 times longer than a standard Bosch Forstner bit.
