Straight Flutes Tap: #1-72, UNF, 2 Flutes, Bottoming, 2B & 3B, High Speed Steel, Bright/Uncoated MPN:TT90022

The straight flutes tap #1-72 with UNF threads allows for versatile use on a variety of materials with ease when working on soft to medium strength metals such as aluminum or brass. With two flutes and bottoming taper configuration, it produces excellent chip evacuation resulting in clean threads on the hole after completing drilling. The use of high-speed steel material offers a good compromise between toughness and heat resistance providing durability during the threading process while reducing built up edges; its bright finish ensures smooth cutting. It has two coatings: 2B (black oxide) which provides rust resistance, and 3B (black nitride) that enhances hardness to reduce wear when drilling into stainless steel hence offering longer tool life for professional or DIY enthusiasts.
