Drill with cylindrical shank and soldered carbide plate Usage : For drilling in a hand or column drill - suitable for drilling in hard steel, cast iron and stainless steel. This design is not as susceptible to vibrations as monolithic carbide drills, i.e. it is ideal if you need to drill screws, hard sheets, etc. in a hand drill - we recommend pre-drilling with a small diameter and making sure that the drill does not overheat - it could lead to de-soldering of the board. Standard: PN 221320 / PN221320 / PN 1320
