Combination Drill Tap: 1/4-28, H3, 2B, 2 Flutes, High Speed Steel MPN:G918817

Combination drill and tap bits combine the functionality of both a drill bit for making holes and a screw tapping tool for cutting threads into pre-drilled holes in one efficient step, streamlining the process for industries requiring high precision in various materials such as metals or plastics. Made from high speed steel (HSS) material ensuring exceptional hardness for withstanding heat generated during thread-forming operations without breaking or blunting while maintaining sharp edges for drilling accuracy. Available in size 1/4-28 UNC, the product features two flutes providing clearance for chips resulting from drilling and tapping tasks as well as a black oxide coating (2B) improving rust prevention during storage or prolonged use without compromising surface finish quality. Ideal applications include machining automotive, aviation parts, electronics assemblies, woodworking furniture constructions, where single-step drill and tap tasks simplify assembly line procedures while adhering to stringent industry standards for accuracy & durability requirements.
