Frequently asked questions

HSS tap vs carbide tap โ€” when to use which?

HSS taps for mild steel, aluminium, brass and stainless at conventional speeds โ€” 50-300 threads per tap depending on material. Carbide taps for CNC production runs in hardened steel, aggressive feeds, or high-volume threading where HSS wears too fast. Carbide costs 4-6ร— more but may last 10ร— longer in the right application.

Straight flute vs spiral flute vs spiral point tap?

Straight flute โ€” general purpose, chips pushed back up the hole, best for through-holes. Spiral flute โ€” chips pulled out of the hole, best for blind holes in tough material. Spiral point (gun tap) โ€” chips pushed forward through the hole, best for through-holes in ductile materials.

How do I prevent a tap from breaking?

Match drill size to tap (most broken taps come from undersize drill holes), use proper cutting oil, keep chips clear, and use a tapping head or rigid tapping cycle on CNC. On manual work, reverse a quarter-turn every half-turn to break chips. Never force a tap.

Can I thread stainless steel with a standard M2 HSS tap?

Yes but it will be slow and the tap will wear fast. For production threading of SS304 or SS316, use M35 (5% cobalt) or M42 (8% cobalt) HSS taps with sulphur-based cutting oil. Run at 30-70% of mild-steel speed.

Which tap thread do I need for gas or pipe fittings?

BSP (British Standard Pipe, parallel or tapered) for water and compressed air fittings across most of Asia, UK and India. NPT (National Pipe Tapered) for US-standard gas and hydraulic fittings. They are NOT interchangeable โ€” the flank angles differ (55ยฐ vs 60ยฐ). Check the drawing before buying.

Do you stock hand tap sets?

Yes โ€” Miranda HSS hand tap sets in metric, BSW, UNC, UNF, BSP. Each set includes taper, plug and bottoming taps for each size. Individual sizes also available. Machine and nut taps ordered separately.
