FEATURES
Quantity: The set includes 25 drill bits, providing a wide range of sizes to accommodate different drilling requirements.
Jobber length: The drill bits in this set have a jobber length design, which means they have a standard length suitable for various drilling applications.
High-Speed Steel (HSS) construction: These drill bits are made from HSS, a type of steel known for its durability and ability to withstand high temperatures generated during drilling. This ensures that the drill bits remain sharp and can efficiently cut through different materials, including metal, wood, plastic, and more.
