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).
