This comprehensive set of threading tools is designed for creating and repairing internal and external threads. Made from high-speed steel for durability and precision, these tools are suitable for a range of materials.

High-speed steel counterbore drill bits are designed for creating countersunk holes with flat bottoms, ideal for fastener applications. These bits feature flutes for efficient chip removal and a pilot section for accurate guidance during machining.

High-speed steel (HSS) multi-diameter step drill bits are designed for drilling multiple hole sizes in thin materials. Each bit features a stepped design, with each step corresponding to a different hole diameter.
