Thread cutting tools 196
Combi-bit 1/4"
Design: With cross-grinding and 1/4" hexagon shank. Application: For drilling core holes, thread drilling and deburring in 1 step. The heat-treated induction zone allows for increased bending elasticity, thus significantly reducing the risk of fracture, thereby up to 50% higher life. 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. Material thickness not more than nominal thread ∅ (M6 = 6 mm material thickness). 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).
