Feature●Thread-rolled spiral drill bits made of high-performance high-speed steel.●The thread-rolled spiral drill bits ensure increased resistance to breakage.●High-performance spiral drill bits for all normal drilling jobs with all common materials.●Applications: for alloy and non-alloy steel and cast steel (up to a strength of 900 N/mm²), grey cast iron, malleable iron, ductile iron, die-cast, sintered iron, nickel silver, graphite, short chip aluminium alloys, brass and bronze.●Packaging unit: in plastic packagingDescription
gerollt-steam-treated Twist-Bohrer aus robustem, High-Speed-Stahl. Die Herstellungsverfahren (keine Störung) auf das Material ist somit wesentlich elastischer. Diese macht es widerstandsfähiger gegen Bruchstellen und für robuste Bohr-Einheiten (z.B. Hand-Bohrmaschine geeignet).
