M4,5x0,5 fine thread hand taps
Hand Tap M4.5x0.5 DIN 2181/2 6H HSS is designed for making M4.5 metric fine threads with a pitch of zero comma five millimeters in structural steels up to eight hundred mega pascals. In assembly practice, an orderly sequence of operations and easy identification of members is provided by Set Taps Manual M4.5x0.5, used in two passes.
Technical parameters: nominal diameter four and a half millimeters; pitch zero comma five millimeters; outline sixty degrees according to ISO 68-1; bore tolerance field class 6H according to ISO 965; right-hand design; straight chip grooves for predictable evacuation. Two-part arrangement according to DIN 2181/2 - inserting member (I) and finishing member (II) - compensates for torsional loads and promotes alignment in narrow holes. The manufacture from high-speed steel in a precision grind stabilizes the edge and reduces micro-crushing. Recommended drill bit for thread: four millimeters; lubrication with emulsion or active oil improves surface quality and edge life.
- Uniform profile shaping - two phases (introduction and finishing) smooth the course of the torque, reducing the risk of seizure.
- Longer blade life - precision grinding of high-speed steel reduces abrasion and sticking, extending sharpening intervals.
- Class 6H fit - keeping the effective diameter within the tolerance range promotes positive "pass/fail" verification.
- Work Order - M4.5x0.5 Hand Tapping Set facilitates unambiguous selection of members and speeds up rotation between passes.
Meeting the requirements of DIN 2181/2 (execution), ISO 68-1 (sixty-degree outline) and ISO 965 (6H tolerances) guarantees compliance with inspection and measuring equipment and repeatable coil geometry in unit and short-run machining.

Frequently asked questions
1. What kind of pre-drilling for M4.5x0.5?
Drill 4 mm (4.5 mm diameter minus 0.5 mm pitch) to get the correct profile fill in Class 6H.
2. Is the M4.5x0.5 DIN 2181 tapping set suitable for blind holes?
Yes, the set can be used in both through-holes and blind holes, in accordance with DIN 2181 and Class 6H.
3. What are the advantages of being made of HSS?
HSS high-speed steel provides high durability, wear resistance and stable operation even under demanding conditions.
