Can be used with hand drills or drilling machines for machining high-alloy steel and metals with tensile strength up to 1100 N/mm², such as heat- and acid-resistant steel, cast iron, bronze, welds, stainless steel, and chrome-nickel steel.
DURABILITY
5% cobalt content provides a sharper cutting edge and increases service life 4 times (compared to HSS-R).
FAST DRILLING
the improved tip and flute geometry increases work speed by 4 times (compared to HSS-R). It also allows faster chip evacuation and reduces heat buildup.
REINFORCED CORE
The core thickness, gradually increasing toward the shank, improves resistance to breakage, especially when working with hand tools (starting from a diameter of 4.8 mm and up).
SLIP PREVENTION
A three-flat shank ensures a secure grip in the chuck and prevents slipping (only for diameters of 5 mm and larger).
