Extra long deep-hole twist drills Profile ground Right-hand cutting Stable special drill bit for drilling extremely deep holes under difficult drilling conditions e.g. with poor chip removal and therefore resulting poor cooling of the tip of the drill bit Suitable for drilling grey cast iron and steels up to max. 1000 N/mm2 Not recommended for nickel-chrome steels or similar materials NORGAU HSS E Type FL 130 010 214 Extra long deep-hole twist drills Profile ground Right-hand cutting High heat resistant drill with wide chip space for very deep holes in difficult conditions such as when swarf congestion hinders the flow of coolant to the drill point or when tool overheating arises from other causes For use in steels and cast steels of high tensile strenght cast iron malleable iron spheroidal iron etc. P M K N S H d1 mm l1 mm l2 mm 010 213.
