Spiral-fluted thread taps with spiral grooves for superior chip evacuation, enabling smoother cutting and reduced binding. Functions and benefits: - Threading and deburring/chamfering of holes in one operation, delivering clean threads and smooth hole edges. - Easy to use on common workshop machines; compatible with hand drills, drill presses, and thread-cutting machines. - Hex shank compatibility provides secure drive and broad tool-holder compatibility. Key attributes: - Function: internal thread cutting and hole chamfering/deburring. - Compatibility: hand drills, drill presses, and thread-cutting machines; available with hex shank chuck. - Performance: improved chip removal, cleaner threads, and easier finishing. Use scenarios: - Automotive repair: tap new threaded holes in metal brackets using a hand drill for quick, reliable threads. - Machinery maintenance: thread and chamfer holes in metal plates on a drill press for precise, repeatable results. - DIY fabrication: prepare aluminum or steel parts by threading holes and deburring edges to ensure smooth fastener fit.
