The Spiral Point STI Tap is a premium vanadium high-speed steel tap designed to cut M20 x 2.5 metric coarse threads in screw thread inserts (STIs). Its 3 flutes deliver increased efficiency and faster chip removal during use, while the plug tap type provides strong thread formation for better pull-out resistance. Additionally, this tap boasts an oxide finish that improves wear protection and rust prevention for extended usage across various industries like aerospace or automotive where STIs are widely utilized for permanent blind rivet-like installation of components in structural applications. The spiral point design allows users to easily initiate the thread at an angle while cutting accurately, ensuring superior engagement with the insert material without galling or damaging its surface.
