Saipor M20 Tap and Die Set is a workshop tap and die kit designed to cut and restore M20 x1.5 threads accurately for repairs and fabrication. Sharp HSS edges and a robust round die help remove damaged threads so seized bolts stop holding up jobs. Is the single-size kit the practical choice for DIYers and workshop technicians?
⚡ At a Glance
- • Cutting Quality: Sharp HSS 6542 (M2) tap with straight flutes for efficient chip evacuation and precise thread cutting
- • Best for: DIY mechanics and workshop technicians restoring or creating M20 x1.5 threads
- • Not ideal for: Users who need a multi-size metric tap and die set rather than a single M20 kit
Single-size M20 x1.5 right-hand tap and round die for creating and repairing threads. Suitable for through and shallow holes in steel, copper, aluminium and cast iron.
Precise Internal Threads – with HSS 6542 straight-flute tap
Tap made from high-speed steel (6542/M2) has hardened cutting edges and straight flutes that channel chips downward during threading. The flute geometry reduces clogging and keeps the cutting edge engaged with the workpiece.
Accurate internal threads that reduce cross-threading and help bolts run true, ideal for repair work and new builds.
Clean External Threads – with high-quality alloy round die
Round die specified for M20 x1.5 has an outside diameter of 45mm and a thickness of 14mm, giving stable contact during chasing and cutting. The die's alloy steel construction keeps edges firm while re-cutting damaged external threads.
Restore or produce external threads that meet standard fittings, improving fit and reducing wobble on bolts and studs.
Flexible Workshop Use – with compatibility for hand and machine tapping
Designed for manual use and for mounting in drill presses, tapping machines, CNC and milling machines, so rotation and feed can be controlled for consistent results. Straight-flute design complements both slow hand speeds and higher-speed machine tapping.
Useful across garage repairs, maintenance benches and small production runs, saving time whether used by hand or on powered equipment.
