RUKO HGB-DIN352-HSS-60°-1/4 Hand Tap Set, 3-Piece, HSS-G, BSPP 1/4 inch, 19 TPI, Right-Hand, DIN 352

Cut clean, accurate internal pipe threads in steel, cast iron, and non-ferrous metals with this RUKO hand tap set. The set includes three taps—taper, plug, and bottoming—for threading through holes or blind holes to full depth. Each tap is made from bright-finished high-speed steel (HSS-G) and conforms to DIN 352 for reliable, standardized thread profiles.

Why choose it

The three-piece set covers every stage of thread cutting, from starting with the taper tap to finishing with the bottoming tap. HSS-G steel holds its edge and resists wear, so you can produce consistent threads job after job. The bright finish reduces friction and helps clear chips.

Ideal use cases

• Creating BSPP threads in pipe fittings, flanges, and manifolds
• Repairing damaged internal threads in hydraulic or pneumatic components
• Workshop and maintenance tasks on machinery and pipework

Good to know

Use a suitable tap wrench with the 5.5 mm square drive. Apply cutting oil for best results and longer tool life. Store taps separately to protect the cutting edges.
