Adhesive Back Sanding Sheet: Aluminum Oxide, 100 Grit, 4-1/2" Wide, 10 yd Long MPN:66261131696

A high-speed steel Spiral Flute Tap M2.5 with a metric size range ensures efficient and precise thread cutting on various types of metal materials such as aluminum or stainless steel, for creating internal threads. The three flutes create faster chip removal, preventing overheating during drilling operations while providing cleaner threads than traditional straight taps, requiring less torque to start cutting. With a Semi-Bottoming design, the tap removes chips more efficiently from inside threads and reduces the number of pecking starts needed for deep hole tapping with better quality threading in harder materials. Its 6H class fit grade increases surface contact points, resulting in excellent chip evacuation and superior grip during cutting, reducing slippage or breakage when encountering hard metal surfaces. Vaporized finish on the tap improves chip-carrying lubricity and rust resistance further increasing tap durability for a longer lifetime, making it suitable for production tapping or repairs of automotive, machinery or aircraft parts where precise threads are critical in their functioning.
