Long Lifetime - The HSS Twist Drill Bit Cobalt provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully ground HSS (h more→igh-speed steel), which provides excellent surface quality, wear resistance and heat protection. Equipped with two cutters and two flutes, chips are removed quickly to make the bit last even longer. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. It has a cylindrical shank system (…

For drilling into general steel, cast steel, cast iron, chilled cast iron, malleable cast iron, non-ferrous heavy and light metal, and abrasive plastic. Features 3xD Self-centering Point angle: 14 more→0 Diameter tolerance m7 Shank tolerance h6 Manufactured to DIN 6537 Sizes 3.00mm to 20.00mm Fire Coating: Applied in Guhring's own coating plants using the PVD process. All round coating can achieve two to three times the performance of TiN, and considerably better than TiALn. Has excellent heat resistance as well as high toughness, therefore it is well-suited for interrupted cutting.

The Dormer A777 drill bits are designed for both professional and industrial use, offering reliable performance in high-stress environments. The 135° split point design reduces walking and ensures more→precise drilling, while the HSS-E cobalt construction extends tool life and maintains sharpness longer, even at high temperatures. Constructed from high-speed steel with 8% cobalt, these drill bits offer exceptional hardness, heat resistance, and wear resistance, making them ideal for demanding applications. Features & Benefits • High speed cobalt steel • Standard spiral flute design • DIN338 • Bronze finish • NAS907J • Right hand rotation/cutting • 135° point …
