SET OF 6 HSS 8% COBALT CORE DRILLS

"Designed in Germany, this HSS-CO 8 annular cutter set is engineered for demanding professional metal drilling applications where high performance and durability are essential. The set includes five core drills in a practical and well-balanced size combination: 2 × Ø14 mm, 2 × Ø18 mm, and 1 × Ø22 mm, neatly packed in a compact and robust storage box.

Manufactured from premium HSS M42 high-speed steel with approximately 8% cobalt, these fully ground annular cutters deliver exceptional hot hardness, superior wear resistance, and long tool life. The cobalt alloy ensures excellent edge retention at high temperatures and significantly reduces the risk of chipping, even under heavy-duty and continuous industrial use.

With a 30 mm cutting length, the cutters are ideal for drilling plates, profiles, and structural steel components. Optimized cutting geometry enables smooth chip evacuation, reduced cutting forces, and stable drilling performance. This results in clean, precise, burr-free holes with high dimensional accuracy.

Equipped with a 19 mm Weldon shank (¾""), the cutters are compatible with all common magnetic drilling machines. Regrindable and designed for tough materials such as stainless steel and alloyed steels, this HSS-CO 8 set delivers near-carbide performance with the toughness and reliability of high-speed steel."
