1. Metric tap: Thread size: M18 x 2; Accuracy: H2; Square shaft width: 11 mm/0.43 inches; Thread length: 30 mm/1.18 inches; Total length: 105 mm/4.13 inches. Clear thread, righthand cutting direction. The tap allows you to create threads or recut damaged or stuck threads. 2. Straight flute design: 4 straight flutes are specially ground to quickly transport chips downward for efficient thread cutting. The heavyduty shank ensures precise and accurate thread cutting, delivering clean and smooth threads with minimal burrs or chips. 3. Wide applications: Suitable for machining continuous or flat blind holes. Compatible with carbon steel, stainless steel, titanium alloys, cast iron, aluminum, nonferrous metals, copper, alloy steel, and hard plastics. Using suitable tapping oil enhances thread quality and extends tap life. 4. M35 and Ticoated tap: Made from M35 speed steel (5% cobalt), known for heat hardness (retains hardness at elevated temperatures), wear resistance, and heat resistance. The titanium coating improves hardness, lubrication, and friction resistance, resulting in longer tool life, better chip evacuation, and thread quality.
