Right Hand Tandem Acme Taps

Right Hand Tandem Acme TapsClick for a Bigger Picture
Tandem Acme Taps. Rough and finish in one pass with class 2G fit.
High speed steel. Ground thread. Right hand.
Tandem style taps produce threads of 10° to 30° included angle in a single pass, without a leadscrew.
These 'stock' acme taps are engineered for cutting mild steel - no guarantee of results cutting other materials.

Call us for left hand, custom, and special thread acme taps.
Be prepared to tell us the size (diameter) and thread needed, the material the tap must cut, the length (depth) of the cut, and whether you are tapping a through hole.
