Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M76x1.5 thread is cut into the wall of a hole with a diameter of 74.5 mm. The thread groove extends 0.75 mm into the wall. A single tap would have to cut the entire groove at once, requiring substantial hand torque and risking breakage. The set divides this work into two passes.
The drawing shows the entire set in operation. Both taps have the same shank and the same length. They differ in their chamfer, the tapered tip: No. 1 has a chamfer spanning 8 threads, while No. 2 spans only 2 threads. The detail windows at the hole wall show how the thread groove deepens after each tap.
| Tap | Chamfer | Chamfer angle | Material removed | How it works in the hole |
|---|---|---|---|---|
| No. 1 – roughing tap | long, 8 threads | 5° | the main portion of the groove | enters smoothly and establishes thread alignment |
| No. 2 – finishing tap | short, 2 threads | 20° | the remainder, to the full profile | follows the cut threads and produces the full 6H profile |
How to distinguish the taps in the set
The chamfer on No. 1 is 4 times as long as the chamfer on No. 2 — the difference is immediately visible when you place them side by side. No. 1 has an incomplete thread profile; only No. 2 has the full profile. The number is also indicated on the shank: No. 1 has one ring, No. 2 has none. Keep the set together and always start with the roughing tap.

Turning sequence: half a turn clockwise, a quarter turn counterclockwise | Between taps: remove chips from the hole
Start with the hole. The drill diameter is easy to calculate: thread diameter 76 mm minus pitch 1.5 mm gives 74.5 mm. An undersized hole is a common cause of a tap twisting off in the workpiece.
Through hole or blind hole – how deep to drill
The set taps both types of holes. In a through hole, the thread extends through the full material thickness. In a blind hole, cut the thread to 190 mm, or 2.5 times the thread diameter (2.5 x 76 mm, shown as 2.5D in the drawing). Drill the hole deeper than the thread. The finishing tap has a chamfer spanning 2 threads, so approx. 2 incomplete threads remain near the bottom. The extra depth below the thread accommodates them along with the chips.
No. 1 – the roughing tap establishes thread alignment
Fit the roughing tap in the tap wrench and position it perpendicular to the surface. Check the angle from two sides, for example with a square. Turn half a turn clockwise, then a quarter turn counterclockwise. Reversing breaks the chip into short pieces – a slight crunch is normal. The first threads determine whether the thread will be straight.
No. 2 – the finishing tap produces the full profile
Back out the roughing tap and remove chips from the hole. Screw the finishing tap into the cut threads by hand – it should engage them on its own. Continue turning at the same rhythm as with the roughing tap. The finishing tap removes the remaining material and cuts the groove to the full profile within tolerance 6H. When it screws in smoothly all the way, the thread is complete – check it with an M76x1.5 screw.
M76x1.5 fine-thread hand taps
Hand Tap M76x1.5 DIN 2181/2 6H HSS is used for precision cutting of metric fine threads in steels up to eight hundred megapascals, copper, and aluminum alloys. It produces threads with high geometric accuracy and a uniform profile, ensuring dimensional stability in precision and small-batch assembly.
Technical specifications: nominal diameter seventy-six millimeters; pitch 1.5 mm; sixty° profile per ISO 68-1; internal thread tolerance class 6H per ISO 965; right-hand direction. Straight flutes allow controlled chip evacuation and reduce the risk of galling. Construction in accordance with DIN 2181/2, with a two-piece configuration (part I – starting tap, part II – finishing tap), ensures uniform torque distribution and maintains axial alignment. Ground high-speed steel (HSS) offers increased resistance to microchipping. In industrial applications, exceptional repeatability and ease of use are provided by M76x1.5 Hand Tap Set. Recommended drill size: 74 mm; cooling with emulsion or active cutting oil improves surface quality and tool life.
- Precise guidance — uniform distribution of machining forces maintains axial alignment and a repeatable thread profile along the entire length.
- Machining repeatability — a clear operating sequence and stable thread geometry are supported by M76x1.5 Hand Tap Set, making it easier to maintain a uniform quality standard.
- Wear resistance — high-speed steel (HSS) maintains consistent cutting edge sharpness, extending service life.
- Class 6H fit — a controlled pitch diameter ensures full compliance with ISO 965 tolerances and successful inspection with gauges.
Meeting the requirements of DIN 2181/2 (construction), ISO 68-1 (metric profile), and ISO 965 (tolerance 6H) ensures full compatibility with measuring equipment. Consistent fit accuracy and high process stability maintain controlled quality in workshop cycles and precision assembly operations.
