Ultimate Protection: Hymnorq 🛡️ Enhanced Hardness Resistance Stainless Steel Review

M42 COBALT STEEL - Constructed by M42 cobalt, a molybdenum series high-speed steel alloy with an additional 8 percent cobalt, measuring high hardness up to HRC67 - 69. SPLIT POINT - 135-degree split point tip for self-centering and safe pilot hole drilling, even in slanting surfaces, in pipes and welds. Centre punching is not necessary. Direct drilling can be done without prior centering or drilling of a pilot hole. GROUND BITS - The bits are fully ground for a smooth surface, which allows even chip removal, reduction of chip friction, extremely true running and precise round holes. WIDELY USED - Ideal for metal manufacturing industries because of its superior red hardness as compared to more conventional high-speed steels. Designed for durability, high heat resistance, and hardened surface. Used for drilling various metals including stainless steel, cast iron, titanium, light-gauge metal, and aluminum. LOWER COST PER HOLE - higher durability than identically constructed HSS drill bits used under the same operating conditions. Much longer tool life means lower cost per hole drilled, although the price is higher.
