Union Butterfield® 1519 General Purpose Straight Flute Pulley Hand Tap, Imperial, 5/8-11, UNC Thread, 4 Flutes, 3B

• Hand taps are used to cut threads in blind or through holes
• High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and non-ferrous materials
• Bright provides a smooth, polished finish on the tool
• It increases chip flow in softer materials such as aluminum, wood and plastic
• These taps have the same major diameters and pitch diameters as standard fractional size taps but with extended shanks for reaching locations inaccessible to regular hand taps
• Although originally designed for tapping pulley holes, the long shank permits tapping other long reach applications
• 1.5 x d average tapping depth
• No coolant channel
