Review on Drill for metal, screw BOSCH PointTeQ 2.608.577.351, 19 pcs. 1 mm by va Mller ᠌

Decided to ate my previous review. I had to drill about 50 holes with a diameter of 2.5 and 3.5 mm in thick metal to a depth of 15-20 mm. With the addition of oil and at low speeds, everything went off with a bang . the drills did not become dull, surprisingly. The quality of the drills is reminiscent of excellent Soviet drills.
