Burkit 7/16 -20 UNF Spiral Point Tap HSS Titanium Coating Spiral Point Plug Threading Tap 7/16 x 20 UNF C27

Spiral point taps are also called screw-point taps suitable for tapping through holes and deep threads. Because of its special chip removal method the spiral point tap avoids the chip s interference with the formed thread surface so that the quality of the finished threaded hole is better than that of the ordinary straight fluted tap. The shallow groove structure ensures cooling and strengthens the torque resistance in the tap processing so that it can have a higher speed and is suitable for processing deep through-hole threads. Due to the chip removal method of the screw point tap it is recommended for vertical machining and through-hole threading. Material: High Speed Steel. Finish: Titanium coating. Cutting Direction: Right Hand. Package Include: 1pc 7/16 -20 UNF Spiral Point Tap. Tips: 1. Please be sure to take protective measures when working you need to wear goggles and protective gloves. 2. Before tapping confirm whether the round hole s diameter is appropriate. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use. 3. When tapping control the speed according to the hardness of the material it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss.
