RUKO HGB-DIN352-HSS-M36x4.0mm Hand Tap Set

This RUKO hand tap set is engineered for cutting metric coarse threads with a nominal diameter of M36 and a 4.0 mm pitch. Unlike single-purpose taps, the three-piece set includes taper, second, and bottoming taps, enabling both through-hole and blind-hole threading in one kit. The taps are made from high-speed steel (HSS) and comply with DIN 352, ensuring consistent geometry and a 60° thread profile angle.

Highlights

• Three taps: taper, second, and bottoming for complete thread cutting
• Metric coarse thread M36 × 4.0 mm
• High-speed steel (HSS) for durability
• DIN 352 standard for reliable interchangeability
• Right-hand cutting direction
• Square shank for secure tool holding

In daily use

The set covers the full threading process: the taper tap starts the thread, the second tap deepens it, and the bottoming tap finishes close to the hole bottom. The square shank fits standard tap wrenches, and the uncoated HSS surface is suitable for general-purpose work in steel and other machinable materials. Recommended pre-drill diameter is 32.0 mm.
