## Description

These drill bits are crafted from 5% Cobalt High Speed Steel and have undergone heat treatment, reaching a hardness of up to HRC 67. They are perfect for drilling in various materials such as cast iron, stainless steel, hard metal, and copper. The upgraded M35 Cobalt construction allows them to perform well in high - temperature applications over extended periods, offering five times the lifespan compared to standard bits. The 135 - degree pilot point tip design helps reduce walking, and the straight round shank design ensures better concentricity for precise hole - drilling. The tapered web helix design provides extra stability in tough applications, while the large spiral flutes make it easier to remove metal chips, enabling fast drilling. Note that for the best results, it's advisable to pre - drill a small hole due to the large drill diameter. Also, as a consumable item, the drill bit may lose its sharpness over time but can be sharpened for continued use.

• 135 pilot point tip reduces walking for efficient drilling
