HSS trepanation drills

• 100% faster - Time savings can be achieved thanks to the following factors: Firstly, the annular cutter cuts the material only at the edge, unlike the twist drill, which cuts the entire diameter. Secondly, two aggressive sharp angles, through the cutting edge, increase drilling speed and reduce resistance.
• 30% greater productivity - Because the annular cutter cuts the material only at the edge of the hole. Less engine energy and drive power are required. The larger the drill diameter, the greater the energy savings.
• Longer lifespan - The cutting edge of annular cutters works less than a twist drill, drilling more holes. The 6 mm thick body together with the special tooth geometry provides greater stability and reduces damage caused by overload.
• HSS trepanation drills with thick walls ensure increased durability and lifespan.
• They have a standard 19 mm Weldon shank.
• Cutting depth of 30 mm.
