Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M10x1 thread is cut into the wall of a hole with a diameter of 9 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 10 mm minus pitch 1 mm gives 9 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 25 mm, or 2.5 times the thread diameter (2.5 x 10 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 M10x1 screw.
M10x1 fine-thread hand taps
Hand Tap M10x1 for cutting internal metric fine threads with a pitch of 1 mm and a 60° profile; this makes the M10x1 hand tap suitable for precision connections requiring a consistent fit.
2-piece set: roughing tap with a long chamfer and finishing tap with a short chamfer; straight flutes for predictable chip evacuation; square shank for a tap wrench; high-speed steel (HSS) with good ductility; manufacturing tolerance 6H (mating with a 6g screw). Compliance: 60° profile per ISO 68-1, dimensions and pitches per ISO 261/262, internal thread tolerances per ISO 965; hand tap set construction per DIN 352. Recommended tap drill size: 9.0 mm. Materials: low-carbon steels, aluminum, brass, copper.
When tapping by hand, maintain axial alignment, use a low-viscosity coolant, and perform a reverse-and-advance cycle every half turn to break the chip and protect the cutting edges in blind and through holes.
- Fit accuracy — class 6H maintains controlled assembly clearance and uniform thread engagement along the entire length.
- Lower cutting torque — the two-stage sequence distributes the load; M10x1 Hand Tap Set makes guidance easier in thin-walled workpieces.
- HSS durability — resistance to varying loads and the ability to resharpen extend service life and maintain consistent roughness.
- Controlled chip evacuation — straight flutes support reverse-and-advance cycles, reducing jamming and surface tearing.
M10x1 Hand Tap Set in a 2-piece configuration, with 6H tolerance and a 60° profile, maintains repeatable thread geometry in precision applications as an M10x1 hand tap set.
