Metric Coarse Thread Hand Taps
Taps - Main Types of Taps
Pipe Taps are supplied with PARALLEL threads or TAPER threads.
These taps are shorter than a similar size of regular hand tap but the design features are the same. They are suitable for hand or machine use.
Parallel Pipe Taps
Parallel pipe taps are used for parallel threading by hand or machine.
1. BSP . .G. Series (made to British Standards): Used when a pressure tight joint on the threads is not required (note:a sealant must be used)
2. NPS (made to American Standards): Used for free-fitting mechanical joints where thread sealing is not required.
Tapered Pipe Taps
Tapered pipe taps are used for tapered threading by hand or machine.
1. BSPT . .Rc. Series (made to British Standards): Used when a pressure joint on threads is required. (note: a sealant must be used).
2. NPT (made to American Standards): Used when a general purpose is required.
FLUTELESS TAPS
These taps are designed for machine tapping in ductile materials, Fluteless taps have no flutes or cutting edges, but have special roll forming lobes with circular lands.
The Advantages of Fluteless Tapping are:
1. Elimination of Tap Breakages: There are no chips to cause jamming or cutting edges to grow dull or breakdown.
2. The Fluteless Design: Produces threads with unbroken metal grain bres. The threads are therefore stronger.
3. Better control of Tapping Hole Sizes: Fluteless taps cannot be forced into lead-error or go oversize when changes occur in machine or operator.s pressure. The clamping of the work piece is important as the method of forming threaded holes compared with conventional tapping creates additional torque of up to 50%.
4. Blind Hole Tapping: No chips to cause interference at the bottom of the hole. In plating operations there are no chips to cause rejects.
5. Longer Tap Life: The Fluteless tap is substantially stronger than a conventional tap; hence there is longer tool life.
6. Faster Tapping Speeds: Produce more tapped pieces per hour.
