M5 Hand Tap Set, 3 Pieces, HSSE TiN Coated, DIN 352, 6HX, for Stainless Steel

In a busy metalworking shop, a machinist faces a stack of stainless steel plates that need clean, precise M5 threads for a custom fixture. Reaching for this 3-piece hand tap set, the job becomes straightforward: the taper tap starts the thread with ease, the plug tap deepens it, and the bottoming tap finishes to the bottom of blind holes. The TiN coating reduces friction and heat, while the cobalt-enriched HSSE steel holds its edge even in tough INOX alloys.

Key specifications

• Thread size: M5 × 0.8 mm (coarse pitch)
• Set includes taper, plug, and bottoming taps
• Material: HSSE (high-speed steel with cobalt) for superior wear resistance
• Coating: Titanium Nitride (TiN) for reduced friction and longer life
• Standard: DIN 352, tolerance 6HX
• Optimized for stainless steel (INOX) and other difficult-to-machine materials
• Straight flutes, right-hand cut, square drive shank
• Overall length: 56 mm, thread length: 16 mm, shank diameter: 4.5 mm

Why choose it

The combination of HSSE steel and TiN coating delivers exceptional performance in stainless steel, where ordinary taps often dull quickly or seize. The 6HX tolerance ensures threads within standard limits, and the three-piece set covers both through and blind holes. The square drive provides a secure grip in tap wrenches, reducing slippage and improving control.

Ideal use cases

• Creating M5 threads in stainless steel components
• Repairing or chasing existing threads in INOX parts
• Manual threading in maintenance, prototyping, and small-batch production

Good to know

Each tap in the set is precision-ground from cobalt-enriched high-speed steel and coated with titanium nitride for a hard, low-friction surface. The straight flutes efficiently evacuate chips in both through and blind holes, while the square drive shank fits standard tap wrenches. With a thread tolerance of 6HX, these taps produce threads that meet common industrial standards.
