ATEAMIR 8-Piece Step & Twist Drill Bit Set, Titanium-Plated HSS, Hex Shank with Case

This 8-piece step and twist drill bit set provides multiple drilling sizes for household repairs, workshop projects, and light-duty applications. The set includes three step drill bits and five twist drill bits made from titanium-plated high-speed steel. The step bits feature 5/64-inch increments with listed drilling ranges of 5/32 to 55/64 inch, 5/32 to 25/32 inch, and 5/32 to 35/64 inch. The five twist bits are supplied in 1/8, 3/16, 1/5, 1/4, and 5/16 inch sizes. A 118-degree split-point tip and two-flute design support controlled drilling starts and chip removal during use. The hex shank design is intended for secure positioning in compatible electric or impact drills. Based on the provided specifications, the bits can be used with aluminum, copper, sheet metal, iron, plastic, and wood, but are not intended for hard steel. A plastic index case is included to keep the eight drill bits organized and accessible between projects. Coolant is recommended during drilling to help manage heat and reduce the risk of heat-related bit damage.
