Discriptions:
- This drill bit contains 5% Cobalt (M35 Cobalt HSS), which increases the strength, the tool life and makes it more heat-resistant. Rockwell Hardness >= 67.
- 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.
- M35 Cobalt 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, Ceramic Materials, High Carbon Steel and Heat-Treated Steel. Pay attention to speed, pressure and heat control during drilling.
