Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M36x1 thread is cut into the wall of a hole with a diameter of 35 mm. The thread groove extends 0.5 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 36 mm minus pitch 1 mm gives 35 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 90 mm, or 2.5 times the thread diameter (2.5 x 36 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 M36x1 screw.
M36x1 fine-thread hand taps
M36X1 Hand Tap DIN 2181/2 6H high-speed steel (HSS) is designed to produce an M36 metric fine thread with a pitch of one millimeter in steels up to eight hundred megapascals; in assembly practice, high process repeatability is achieved through the sequential use of M36x1 Hand Tap Set, which organizes the passes and stabilizes guidance along the hole axis.
Construction specifications: nominal diameter thirty-six millimeters; pitch one millimeter; sixty° profile per ISO 68-1; tolerances per ISO 965 (internal thread class 6H); right-hand; straight flutes for predictable chip evacuation. Ground high-speed steel (HSS) construction reduces microchipping and maintains cutting edge sharpness. The two-part system in accordance with DIN 2181/2 — first (starter) and second (finisher) — evenly distributes torsional loads and supports axial alignment. Recommended tap drill diameter: thirty-five millimeters; M36x1 hand tap operates most reliably with emulsion or active cutting oil, improving surface quality and cutting edge life.
- Controlled profile formation — dividing the process into starting and finishing passes reduces torque pulsations and limits jamming.
- Long cutting edge life — ground high-speed steel (HSS) maintains low microroughness, slowing dulling in structural steels.
- 6H fit accuracy — a controlled pitch diameter helps achieve a passing GO/NO-GO inspection result.
- Order and repeatability — clear tap markings organize the sequence; M36x1 Hand Tap Set reduces selection time and maintains consistency between successive passes.
Compliance with DIN 2181/2 (construction), ISO 68-1 (sixty° profile), and ISO 965 (internal thread tolerance class 6H) ensures compatibility with measuring equipment, while the Hand Tap M36X1 DIN 2181/2 6H HSS guarantees predictable geometry and dimensional consistency in one-off and small-batch machining.

Frequently asked questions
Yes, the set can be used in both through holes and blind holes, in accordance with DIN 2181 and class 6H.
The set consists of two taps — a roughing tap and a finishing tap, which guarantee a fully formed thread when used in sequence.
The HSS tool works well in low-carbon steel, aluminum, brass, and other materials with good machinability.
