M21x1.5 fine thread hand taps
Hand Tap M21X1.5 DIN 2181/2 HSS dedicated to cutting metric fine-coil threads in steel and cast iron; in service applications, hand Tap M21x1.5 maintains a 60-degree profile and a stable 6H grade hole fit.
Geometric layout and material: size M21, pitch P=1.5; right-hand direction; HSS high-speed steel in design, ground finish; straight grooves for uniform chip breakage; cylindrical shank with square driver; recommended 19.5 mm drill bit to ensure proper profile filling and axial guidance even in hard-to-reach holes.
- Surface quality. Ground cutting edges and straight grooves promote low roughness and coil repeatability.
- Entry stability. A stepped overlay balances cutting forces and reduces the risk of starting zone decalibration.
- Smoothness of runs. Set Taps m21x1.5 handhelds facilitate the transition from peeling to finishing without loss of alignment.
- Precision fit. The 6H bore works with 6g male threads to maintain nominal clearance and clean outline.
Standard references: manufacture according to DIN 2181/2; metric 60-degree outline according to ISO 68-1; series and pitch according to ISO 261/262; tolerances for internal threads according to ISO 965 (class 6H). The M21X1.5 DIN 2181/2 HSS Hand Thread Set provides controlled coil geometry and predictable results in unit and assembly operations.
