Set of 25 RUKO high toughness HSSE-Co 5 drill bits in plastic case

The Ruko-215215RO 25-piece drill bit set, manufactured according to DIN 338, is designed to deliver exceptional performance when drilling difficult-to-machine materials. These drill bits are made of HSSE-Co 5 high-speed steel, containing 5% cobalt, which gives them high toughness and heat resistance. Their robust design and pronounced hot hardening resistance make them ideal for drilling stainless steel, as well as other demanding materials such as acid- and heat-resistant steel, with a tensile strength of up to 1100 N/mm².

The bronzed surface coating and thickened core of these drill bits ensure long-lasting durability and optimal performance in industrial applications.
