Crown drill / puncher / drill bit bi-metal, jigsaw Average: according to the selected variant Max. drilling depth: 38mm Catalog number: 20.1500 Cutting conditions - see attached catalog sheet Material: HSS Co8 (high speed steel with 8% cobalt) Fine tooth - toothing 4/6 " Suitable for drilling in: alloy and common steels, stainless steel, non-ferrous materials and light metals * From a diameter of 160 mm, drilling into metal is not recommended - only non-metallic materials, wood, plastic, etc. HSS Co8 bimetal jigsaw. Fine gearing is very well suited for metals. It ensures a quieter operation and requires less effort. Due to less heat generation during cutting, the service life is extended, especially for metals. Suitable for alloy and common steels (up to 750N / mm2), high chromium steels such as stainless steel, acid-resistant steels, non-ferrous materials and light metals.

Short drill with cylindrical shank, material HSS Standard: PN 2905 / DIN1897RNHSS Form C - ground conical surface with shortening of the transverse edge - type C PROFI - tools produced by grinding and precision milling Powerful drills recommended for common drilling on automatic and turret lathes in components made of non-alloy and alloy steel, steel castings up to 900 N / mm2, gray, malleable and ductile cast iron, sintered steel, short-chip aluminum alloys, bronze, tough brass . Especially suitable for drilling thin-walled materials.

Short drill with cylindrical shank, material HSS Co5 Standard: PN 2905 T1000 / DIN 1897 GT100 Form C - ground conical surface with shortening of the transverse edge - type C PROFI - tools produced by grinding and precision milling High-performance drills with increased heat resistance with a special groove profile recommended for drilling in alloy steel parts, steel castings with strength above 1000 N / mm2, especially steels for volume hot and cold forming, rolls of rolling mills, steels for cementing and tempering, stainless steel.

Right-handed ground twist drill with slow helix, for hard brittle materials with brittle chips Drill length: Classic short series - lengths see enclosed catalog sheet Edge angle: 118 ° Helix angle: 10 ° - 15 ° Material: HSS - High speed steel Standard: PN2911, DIN338 RH Usage: General - hand, stand, column drills Non-ferrous metals - aluminum, copper, bronze, brass, plastics, resins and horn, eternit, slate, mica, hard rubber, etc. materials with friable chips

Crown drill / puncher / drill bit bi-metal Average: according to the selected variant Max. drilling depth: 38mm Cutting conditions - see the enclosed catalog sheet Suitable for drilling in: non-alloy steel, non-ferrous and light metals, plastics, plasterboard, reinforced boards, plywood and woodworking HSS bimetallic jigsaws with variable gearing. For easy-to-machine materials, the variable toothing ensures a more even tool passage and requires less effort. Thanks to lower vibrations and heat generation during cutting, up to three times longer service life is achieved. Suitable for non-alloy steels up to 700N / mm2, non-ferrous and light metals, plastics, plasterboard boards, reinforced boards, plywood and for working with wood.

Cobalt core drill / jig / drill bit bi-metal Average: according to the selected variant Max. drilling depth: 38mm Cutting conditions - see the enclosed catalog sheet Material: HSS Co8 (high speed steel with 8% cobalt) Fine tooth Suitable for drilling in: alloy and common steels, stainless steel, non-ferrous materials and light metals HSS Co 8 bimetal jigsaw. Fine gearing is very well suited for metals. It ensures a quieter operation and requires less effort. Due to less heat generation during cutting, the service life is extended, especially for metals. Suitable for alloy and common steels (up to 1100N / mm2), high chromium steels such as stainless steel, acid-resistant steels, non-ferrous materials and light metals.

Carbide core drill / puncher / drill bit is made of one piece - including shank. Diameter: according to the selected variant (average tolerance 1mm) Drilling depth: 25mm It has powered carbide teeth, which allow easier drilling with less pressure force. Precise guidance is ensured by a removable guide drill with a diameter of 6 mm. The spring on the drill bit is used for easy removal of the drilled material. The guide drill is secured with an Allen key. The drill has a ground surface. The teeth are 3 mm wide, which ensures more economical drilling. The clamping shank is adapted for clamping in a three-jaw chuck. Application: Column drill , or hand drill with drills up to a diameter of about 40-50 mm - but it is necessary to keep the drilling axis and always keep all the cutting edges in engagement. If you do not keep all the blades in engagement or you are not able to keep the drill in the drilling axis (jerks, shocks, etc.), the carbide blade may be chipped - ie irreversible damage to the tool.
