21PCS Cobalt Drill Bits Set with Triangle Shank and Golden Ratio Tip
GUARANTEED SAFE CHECKOUT
INTOO is proud to offer a high-performance and reliable 21PCS COBALT DRILL BIT SET. Made from premium HSS M35 material with 5% cobalt content, these drill bits are designed for heavy industry use on hard metals like stainless steel. The 135-degree angle point with Golden Ratio Tip ensures clean and smooth holes, while the triangle shank provides a secure grip in the chuck.
Sizes range from 1/16 to 3/8, with each drill bit featuring a unique patented tip design for improved performance. The drills have a hardness of 63-64 Rockwell, making them incredibly durable and long-lasting. To ensure the best results, we recommend using a low RPM of 500 when operating the drills.
For safety reasons, we advise wearing masks and gloves when drilling. Additionally, allowing the drills to cool down between uses will significantly extend their lifespan. Each set comes in a strong metal storage box, keeping your drills organized and secure when not in use.
Invest in the INTOO 21PCS COBALT DRILL BIT SET for all your heavy-duty drilling needs. Experience the difference in quality and performance with our premium drill bits.
