Tap for Helical Insert

Manufacturer part: 91709A119

Add threads to holes in preparation for installing helical inserts. These taps are made of uncoated high-speed steel and are for use on most metal and plastic. The square shank is compatible with tap wrenches and tap holders for drill presses and milling machines.Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
