Design: HSS, bright surface. With 1/4" hexagon shank
Application: For drilling core holes, thread drilling and deburring in one step, for regular metric threads according to ISO DIN 13.
Combi-bits are designed for thread drilling with cordless drills and handheld drills with left and right motion. However, they are also suitable for drilling by hand and on stationary drilling machines. Only through-holes with up to a maximum thread depth of 1 x D can be produced. Particularly suitable for assembly work and small batches. Make sure that the tool axis and hole axis are precisely aligned and use appropriate cutting oil (order no. 9829).
