Straight Flute Taps, Tap Type: Machine , Thread Size (Inch): 1-1/2-6 , Overall Length (Decimal Inch): 6.3750 , Thread Standard: UNC , Chamfer: Bottoming MPN:2749240

Straight flute taps, also known as single or plug tap, are cutting tools designed to create threaded holes into components during tapping operations. This machine tap type ensures a better grip of the workpiece while producing threads with high precision by cutting across each pass through spiral grooves, allowing for continuous threading without back-boring operations. The UNC 1-1/2-6 standard and bottoming chamfer make it suitable for creating uniform threads ranging from 1/4-60 with reduced undercut on internal holes or threads, providing strong thread engagement in fasteners and components manufactured from high-speed steel (HSS).
