Cobalt Drill Bits

Cobalt M35 drill bits are an essential tool for anyone needing to drill through tough materials with precision and durability, making them a staple in both industrial and professional settings. Their ability to maintain performance under stress and heat makes them a top choice for high-demand drilling applications.

• Cobalt Alloy Composition: The M35 drill bits are made from a high-speed steel (HSS) alloy enriched with 5% cobalt, enhancing their strength, hardness, and ability to withstand high temperatures without losing their cutting edge.
• Heat Resistance: The cobalt content allows M35 drill bits to operate at higher temperatures compared to standard HSS bits. This makes them perfect for drilling through hard metals like stainless steel, cast iron, titanium, and other alloys without the risk of overheating or tool failure.
• Superior Hardness: M35 drill bits maintain their sharpness and cutting efficiency longer than conventional drill bits, providing precise, clean holes even after extensive use.
• Wear Resistance: The toughness of cobalt M35 drill bits gives them excellent wear resistance, reducing the need for frequent replacements and making them a cost-effective choice for heavy-duty drilling tasks.
• Versatility: While primarily used for drilling into metal, M35 drill bits can also handle a variety of other materials, including hard plastics and wood, making them a versatile tool for both professional and DIY applications.
• HRC = 63
• Made in China

Due to the nature of drill bits and their varying uses, they are not guaranteed against breakage or damage.With budget drill bits, the tips may need sharpening/final finishing using a sharpening stone, if they fail to initially cut or wear after use.
