two-fluted gun drills type tbz-solid carbide head suitable for cast iron aluminium-alloys contents silicon more than 8 and other short-chipping non-ferrous materials we are able to manufacture these solid carbide head gun drills in the diameter range from 6.0 to 27.0 mm with a total length of max 1000 mm please use the form on page 16 for special inquiries orders for certain materials a coating is required as the successful application of gun drills with a bright surface finish cannot be guaranteed for chilled cast iron and al cast alloys with a si-content of more than 10 we recommend our molyglide coating however two-fluted gun drills type tbz-solid carbide head can only be coated with molyglide up to an overall length of max 500 mm due to the technical production process the essential advantage of the two-fluted gun drills compared to the single-fluted ones is a better performance thanks to the higher feed rate this results out of the double cutting edges and two flutes of course
