ULTRA TiAlN COATING UP TO 10X LONGER LIFE - Our drill bits are coated with TiAlN, a new coating material that minimizes wear during drilling. This coating extends the life of the drill bit up to 10 times.

M35 COBALT PREMIUM STEP BIT - Our set is made from M35 steel, a high-speed steel containing cobalt. This material boasts high red hardness, wear resistance, and sintering resistance. Proper heat treatment can achieve a hardness level of HRC 64-66.

With a total of 34 step sizes, our Bolt Extractor Set is perfect for various materials such as stainless steel, metal sheet, wood, plastic, aluminum sheet, copper, and other metal sheets.
