Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M75x2 thread is cut into the wall of a hole with a diameter of 73 mm. The thread groove extends 1 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 75 mm minus pitch 2 mm gives 73 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 187.5 mm, or 2.5 times the thread diameter (2.5 x 75 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 M75x2 screw.
M75x2 fine-thread hand taps
Hand Tap M75x2 DIN 2181/2 6H HSS is a precision tool designed to produce metric fine threads with a diameter of seventy-five millimeters and a pitch of two millimeters. Suitable for structural steels, alloy steels, and nonferrous metals, it provides a stable thread profile, accurate fit, and repeatable results in one-off and small-batch machining.
Design specifications: nominal diameter 75 mm; pitch 2 mm; sixty° profile per ISO 68-1; internal thread tolerance class 6H per ISO 965; right-hand thread. Straight flutes promote controlled chip evacuation, while the two-piece design in accordance with DIN 2181/2 — a starter tap (I) and a finishing tap (II) — balances torque and maintains axial alignment. Ground high-speed steel (HSS) retains cutting edge sharpness and resistance to microcracking, ensuring dimensional repeatability. In workshop practice, clearly identifiable work stages and consistent operations are ensured by M75x2 Hand Tap Set. Recommended drill diameter: 73 mm; cooling with emulsion or active cutting oil extends cutting edge life and improves surface smoothness.
- Stable operation — the two-stage sequence reduces torque spikes and helps maintain a uniform thread profile.
- Cutting edge durability — HSS with high resistance to microcracking ensures a long service life while maintaining profile accuracy.
- Class 6H accuracy — maintenance of the effective diameter is confirmed by GO / NO-GO gauge checks.
- Process ergonomics — predictable operation and clearly defined stages make it easy to maintain the quality standard in every production batch.
Construction in accordance with DIN 2181/2, ISO 68-1, and ISO 965 ensures fully repeatable parameters and compatibility with inspection equipment. The overall design ensures dimensional stability, smooth machining, and smooth operation, delivering precise results in industrial conditions. In assembly and repair cycles, consistent machining quality is supported by M75x2 Hand Tap Set, ensuring consistency and accuracy at every stage of the work.
