Drills

Quality Czech step drill for metal Step drill for holes for shank and countersunk screw head 90 ° Helix angle: 25 ° to 30 ° Tip angle: 118 ° and 90 ° Form: A Material: HSS Standard: CSN221255 When drilling, lower cutting conditions than the standards for conventional drills must be selected. Usage: Step drills with four chamfers are recommended for drilling holes for screws and at the same time countersinking for cylindrical screw heads in components made of non-alloy and alloy steel and cast steel up to 800 N / mm2, gray, malleable and ductile cast iron, aluminum alloys, etc. If you need a different size, see the enclosed photos - see DIN8375 data sheet - for German screws.

Quality Czech step drill for metal Step drill for thread holes and countersunk screw head 90 ° Helix angle: 25 ° to 30 ° Tip angle: 118 ° and 90 ° Form: A Material: HSS Standard: CSN221259 When drilling, lower cutting conditions than the standards for conventional drills must be selected. Usage: Step drills with four chamfers are recommended for drilling holes for screws and at the same time countersinking for cylindrical screw heads in components made of non-alloy and alloy steel and cast steel up to 800 N / mm2, gray, malleable and ductile cast iron, aluminum alloys, etc. If you need a different size, see the enclosed photos - see DIN8379 data sheet - for German screws.

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

Drill with conical shank and soldered TK insert Clamping shank: morse Suitable for drilling in steel, cast iron and stainless steel Standard: PN 221330 / PN221330 / PN 1330

Drill with cylindrical shank and brazed carbide insert Usage: For drilling in a hand or column drill - suitable for drilling in hard steels, cast iron and stainless steels. This design is not as prone to vibration as solid carbide drills, ie it is ideal if you need to drill screws, hard plates, etc. in a hand drill - we recommend pre-drilling with a small diameter and making sure that the drill does not overheat - the plate could be desoldered. Standard: PN 221320 / PN221320 / PN 1320
