Hand taps M2,5x0,35 fine threads
Hand Tap M2.5x0.35 DIN 352/2 6H HSS is designed for precision cutting of metric micro threads in structural steels, alloy steels and cast iron; in assembly applications, hand Tap M2.5x0.35 maintains a 60-degree outline and repeatable 6H grade hole fit.
Working dimensions and design: size M2.5, pitch P=0.35; right-hand direction; HSS high-speed steel in ground design; straight grooves for controlled evacuation of fine chips; cylindrical shank with square driver for knob work; 2.15 mm drill recommended to ensure proper profile fill and axial guidance during peeling and finishing.
- Stage work. The use of a set of M2.5x0.35 hand taps facilitates the transition from chipping to finishing without loss of alignment.
- Fitting precision. The 6H grade hole mates with 6g external threads to guarantee nominal clearance and dimensional compatibility of the joint.
- Micro-cutting stability. Graduated nut reduces torsional torque and stabilizes the entry zone at small diameters.
- Surface quality. Ground microgeometry and straight grooves reduce burrs, promoting low coil roughness.
Standardization and tolerances: design according to DIN 352/2; metric 60-degree outline according to ISO 68-1; dimensional series and pitch according to ISO 261/262; tolerances for internal threads according to ISO 965 (6H hole). Set Taps The M2.5x0.35 DIN 352/2 6H HSS handhelds provide predictable coil geometry and stable results in precision assembly processes.

Frequently asked questions
1.What drill bit should I choose under M2.5x0.35?
The recommended diameter of the drill bit is 2.15 mm, which makes it possible to achieve the right fullness of the coil at a pitch of 0.35 mm.
2.What materials are suitable for HSS?
Low-carbon and structural steels, aluminum, brass and copper. For stainless and acid-resistant steels, consider the cobalt version (HSS-Co) and special coolants.
3.How to guide hand threading to avoid breakage?
Maintain alignment in the knob, use a low-viscosity coolant, and perform a "back-turn" cycle every half turn for chip breakage. Don't use force - increase the torque smoothly.
