HSS 1.0-13.0mm Metal Drill Bit Set 25 Pieces
Set of 25 pcs. gold-black metal drills 1.0-13.0 mm made of high-speed steel 4341 HSS, TiN (titanium nitride) coated. Drills according to DIN 338. Cylindrical handle.

Drills designed for making through and blind holes. They have two central blades ground at an angle of 135° and grooves that effectively remove chips up the hole.

TiN-coated drills are designed especially for machining difficult-to-cut materials. The use of TiN coating increases the hardness of drills, allows for the acceleration of the cutting process and allows for better quality of processed elements. The titanium nitride layer reduces the wear of the blade by reducing the friction force, and therefore extends the life of drills.

Drills packed in a convenient storage plastic box.
