WS-Staketen-Bormax 2.0 with interchangeable centering drill. The WS-Staketen-Bormax 2.0 features an interchangeable centering or guiding drill, two offset main cutting edges with grooves, and serrated guiding drills with longitudinal grooves. This design significantly reduces feed forces and minimizes friction and heat generation. The package includes the Staketen-Bormax, a matching centering drill, two guiding drills (4 mm), an Allen key, and a 250 mm extension with hex shank for improved power transmission. The guiding drill is ideal for drilling at angles other than 90° to the material surface, such as in stair construction.
