🔨【M35 Cobalt Drill Bit】 The M35 cobalt drill bit is known for its durability, sharpness, and strength. It is ideal for cutting through stainless steel, iron castings, copper, aluminum, as well as other soft metals and materials like plastics and wood.

🔨【Quick and Efficient】 These cobalt drill bits are designed for efficient cutting on both soft and hard surfaces. With a 135-degree point tip and a twist design, they offer faster cutting while self-centering to prevent walk-off. Additionally, they ensure faster chip and particle removal for smooth drilling.

🔨【HSS Drill Bit Set】 This HSS cobalt drill bit set is specifically crafted for hardened steel with exceptional cutting performance. With 13 sets of drill bits included, this set is built to last. The inserts are hardened and polished, ensuring sharpness and precise cutting without any wobbling.

🔨【Warm Tips】 When using these drill bits, it is important to ensure a vertical angle before drilling to allow the bit to smoothly enter the hole. If you encounter difficulty pulling out the drill bit, it may be stuck in the protective sponge below. In such cases, repeat the vertical motion gently to avoid any breakage.
