26625A34 Uncoated High-Speed Steel General Purpose Tap. Bottoming Chamfer, 1-5/8″-12 Thread Size, 2″ Thread Length.
Cut threads into most metal and plastic. These high-speed steel taps are durable enough for small-scale tapping jobs, but they’re not recommended for production use. For better chip flow, choose a tap with fewer flutes.
Drive square-shank taps with a tap wrench or use them in a tap holder for drill presses and milling machines. Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Bottoming-chamfer taps cut into the workpiece with just 1-2 chamfered threads. This short chamfer lets them thread holes closer to the bottom than other taps, but they require more torque to start threads.
