Material Performance
The M35 HSS (which includes 5% cobalt) offers remarkable heat and wear resistance, making these bits particularly effective for drilling through tough materials like stainless steel, cast iron, titanium alloys, and high-temperature alloys. The high strength, hardness, and durability associated with M35 steel significantly enhance the tool life compared to standard drill bits.

Design Features
Each drill bit features a 135-degree split point that is complemented by a round straight shank. This design not only ensures self-centering, thereby preventing the bits from wandering during drilling, but also contributes to both precision and speed in drilling tasks. The twist design with two flutes is especially beneficial as it helps in quickly evacuating debris, reducing friction, and minimizing heat buildup for a cooler drilling operation.

Storage and Organization
To facilitate convenient storage, the drill bit set comes with a holder that includes a size index. This feature makes it easy to categorize and organize the bits, ensuring quick access during projects.
