Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M9x0.5 thread is cut into the wall of a hole with a diameter of 8.5 mm. The thread groove extends 0.25 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 9 mm minus pitch 0.5 mm gives 8.5 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 22.5 mm, or 2.5 times the thread diameter (2.5 x 9 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 M9x0.5 screw.
M9x0.5 hand taps
Hand Tap M9x0.5 DIN 2181/2 6H HSS is designed to produce precision fine threads in structural steels, brass, and aluminum alloys. Accurate manufacture and refined geometry ensure a clean thread profile and a stable class 6H fit. In workshop applications, high dimensional repeatability and smooth operation are supported by M9x0.5 Hand Tap Set, allowing controlled machining even in blind holes.
Specifications include a nominal diameter of nine millimeters, a pitch of 0.5 millimeters, a sixty° profile according to ISO 68-1, and an internal thread tolerance of 6H according to ISO 965. The two-piece arrangement according to DIN 2181/2 — starter tap (I) and finishing tap (II) — balances torsional loads and improves axial guidance. Ground high-speed steel (HSS) provides wear resistance and maintains a sharp cutting edge, while lubrication with an emulsion or active cutting oil significantly improves surface quality.
- Machining stability — dividing the work between two taps reduces vibration and helps maintain alignment within tight tolerances.
- Cutting edge life — ground high-speed steel (HSS) minimizes the risk of microchipping and loss of sharpness.
- Precise 6H fit — the pitch diameter is checked with GO / NO-GO gauges.
- Smooth operation — the use of M9x0.5 Hand Tap Set ensures a smooth transition between cutting stages and maintains dimensional repeatability.
Meeting the requirements of DIN 2181/2, ISO 68-1, and ISO 965 ensures full compatibility with inspection equipment. In industrial practice, the tool maintains stable profile geometry and high surface quality even when machining materials with increased hardness, making it a reliable solution for precision production.
Stages of cutting an M9x0.5 thread with a 2-piece set: roughing tap and finishing tap
1. What pilot hole is required for M9x0.5?
Drill to 8.5 mm (diameter 9 mm minus pitch 0.5 mm) to achieve the correct thread engagement in class 6H.
2. What materials is the M9x0.5 tap designed for?
The HSS tool works well in low-carbon steel, aluminum, brass, and other materials with good machinability.
3. What are the advantages of HSS construction?
High-speed steel (HSS) provides high durability, abrasion resistance, and stable operation even under demanding conditions.
