M12×1.75 Uncoated High Speed Steel Precision Spiral Point Flute Taps Left Hand Hole Threaded Threading Tapping Blind Hole Tools

Tips for Optimal Use: Always use cutting fluid for smoother operation and extended tap life. First create the workpiece bore diameter with a drill that matches the screw thread size minor diameter,Start with a pilot hole slightly smaller than the tap's minor diameter. Maintain proper alignment to ensure straight, accurate threads.Please use a cutting speed of 5m/min or less. Clean the tap after each use to prevent material buildup. Store in a dry, protected environment to maintain sharpness. Plug-chamfer taps are versatile for most tapping applications, with 3 to 5 chamfered threads for start-to-finish tapping. Bottoming-chamfer taps form threads with 1 to 2 chamfered threads, can thread holes closer to the bottom but need more torque to start. The Bright finish on these taps provides a smooth, polished surface. The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. The TaC coating such as high hardness, anti-adhesion, low friction coefficient.

• High Hardness and Wear Resistance:HSS-Co,uncoated precision Spiral taps provides Fine-Toothed.polished surface,This enables the taps to maintain good hardness and cutting performance even in high-temperature environments, reducing the frequency of tap replacement, and improving the processing efficiency.
• Good theading Performancel:Good cutting performance and chip evacuation performance, Durable Spiral Point Flute Taps can achieve higher cutting speeds and feed rates, preventing clogging and ensuring a smooth tapping process even in through holes.
• High-Precision Machining:High-precision thread machining,high dimensional accuracy and low surface roughness.delivering precise threads with minimal effort. Achieve precise threading with minimal vibration, enhancing your control and accuracy during use.
• Versatile Applications: Suitable for machining a variety of materials, such as common structural cast iron, aluminum alloy, copper alloy, etc., including Industrial automotive, aerospace, and general manufacturing, used on machines such as a drill presses, lathes, or CNC Machining
