Features:
1. Superior Hardness with M35 Cobalt Steel: Constructed from durable M35 cobalt steel alloy, which includes molybdenum and cobalt, the drill bits offer exceptional hardness of up to 67 on the Rockwell scale. Experience up to 12 times the lifespan of standard high-speed steel (HSS) drill bits
2. Precise Drilling with 135° Split Point Tip: Equipped with a 135-degree split point tip, these drill bits provide a self-centering feature that allows for rapid metal penetration with minimal pressure, preventing the bit from 'walking' or wandering during drilling
3. Optimal for Tough Metals: Specifically engineered to tackle hard metals, these bits excel when working with stainless steel and cast iron. For softer materials, easily adjust the RPM for effective drilling without damaging the bit. Note: Not intended for use with hardened or high carbon steel
4. Comprehensive 74-Piece Set: This complete set features 74 pieces of M35 cobalt steel twist drill bits, complying with the German DIN338 standard. Assorted sizes range from 1mm to 8mm, ensuring you have the right bit for every job
5. Organized and Accessible Packaging: Stay organized with the drill bits neatly packed in individual plastic bags, each labeled with sizes clearly outlined in an enclosed size chart for accurate and fast bit selection.
