Carbon Steel Fractional Bottoming Taps

We are Supplier of Carbon Steel Bottoming Taps, ideal for cutting right-hand internal threads. The Taps have chamfered threads at the tip that is enough to start the hole and taps all the way to the bottom. Our Bottoming Taps are made from heat-treated carbon steel, they are rust and tarnish-resistant tools that work equally well in plastic drilling applications. The rolled threads are more accurate and cleaner than machined threads. The tool is also ideal for routine maintenance, repair, and works for rethreading.

NOTE: Available in Standard and Non - Standard sizes and dimensions as required by the customer.
