M27x1.5 hand taps for stainless steel
Hand Tap M27X1.5 ISO 529/2 6H HSS designed for manual cutting of fine-coil metric threads; for M27x1.5, it maintains a 60-degree profile, axial guidance and predictable 6H grade hole fit in steel and cast iron.
Geometric data and material: size M27, pitch P=1.5; right-hand direction; HSS in ground design; straight grooves for uniform chip formation and removal; stepped cap; cylindrical shank with square driver; recommended 25.5 mm drill bit for proper profile filling and stable axial guidance.
- Stable take-off - Input chamfering with the nut reduces edge loads and the risk of calibrating the input.
- Smoothness of stages - Set Taps manual M27x1.5 speeds up reaching the full profile without compromising alignment.
- Fitting accuracy - Grade 6H is compatible with 6g, which maintains nominal clearance and a clean joint outline.
- Coil smoothness - Ground blades and straight grooves reduce burrs, supporting low roughness.
The M27x1.5 ISO 529/2 6H HSShand tapping set provides repeatable coil geometry and predictable results in precision assembly and unit machining. Standards basics: ISO 529/2 - dimensions and design of hand taps; ISO 68-1 - 60-degree metric outline; ISO 261/262 - ranks and pitches; ISO 965 - tolerances for internal threads in Class 6H.
