Taps

Emuge is the premier supplier of taps for the most demanding tapping applications. Our taps are used in the most industries including automotive, aerospace and high-tech.

We supply a full range of taps and carry metric and english unit versions. For more information about each tap line please browse the categories in the navigation bar above, or use our Interactive Tap Finder to determine the best tool for your needs.

1. Overall Tap Length

• Short machine screw taps have an overall length according to DIN Standard dimensions.
• Machine taps EMUGE Rekord 1 (with reinforced shank) and Rekord 2 (with reduced shank) are made longer according to European standards.
• Such taps can easily be chucked with modern tapping attachments and yet aid in chip removal.
• Metric taps are available with overall tap lengths according to DIN and ANSI standards.

2. Thread Length

• EMUGE's tap thread length is determined by our vast experience regarding different threading applications.
• We have designed taps with a reinforced shank which have a neck to create longer effective threading lengths.
• The thread lengths of taper thread taps, such as NPTF Pipe, are designed to minimum lengths making them suitable for all kinds of holders.

3. Shanks and Squares

• The shank and square dimensions of all EMUGE Taps are made to DIN Standards so that they can readily fit any available tap holder without difficulty.
• Metric taps are available with shank and square sizes according to DIN and ANSI standards.
