【M35 Cobalt Drill Bit】This drill bit contains 5% Cobalt (M35 Cobalt HSS), which increases the strength, extend the tool life and makes it more heat-resistant. Rockwell Hardness >= 67.

【Multiple Application】 M35 Coblat HSS is perfectly suitable for Hard Metals, such as Stainless Steel and Cast Iron. Can be used for Wood, Aluminum Alloy and Other Softer Metals. NOT for Glass or Ceramic Materials. Pay attention to speed, pressure and heat control during drilling.
【Fully Ground Process & 135° Split Point】No center punch is needed. Fully ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance. 135° split point with straight shank prevents walking and makes drilling precise and faster.

Title: Useless for stainless steel
Review: Bought to drill holes in 2mm stainless steel. Didn’t even mark the surface and just spun all over the place. Absolute waste of money, time and effort. Forced to provide one star to submit a review but worth none at all. Be warned., don’t but these for stainless steel.

Review: I had gone through 3 HSS black cobalt jobber bits (also from Amazon), drilling through 1/4″ mild steel brackets prior to switching to these bits. A single bit did the work of the prior 3 bits combined, and it is still almost as sharp as new. A very unexpected and pleasant surprise. I would definitely buy this product, from this vendor, again.
