Roughing tap and finishing tap – how much material each removes
Division of work in the 1–2 set
The M62x1.5 thread is cut into the wall of a hole with a diameter of 60.5 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.
How to tap an M62x1.5 hole – sequence 1, 2
Hand tapping step by step
Thread M62x1.5 in four steps
Drill bit 60.5 mm
Chamfer 8 threads
Chamfer 2 threads
Tolerance 6H
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 62 mm minus pitch 1.5 mm gives 60.5 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 155 mm, or 2.5 times the thread diameter (2.5 x 62 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 M62x1.5 screw.
M62x1.5 fine-thread hand taps
Hand Tap M62x1.5 DIN 2181/2 6H HSS is used to produce metric fine threads with a diameter of sixty-two millimeters and a pitch of one and a half millimeters in structural steels and metal alloys with tensile strengths up to eight hundred megapascals. In workshop practice, an important role is played by M62x1.5 Hand Tap Set, which helps maintain the working sequence and improves axial stability.
Design parameters: nominal diameter sixty-two millimeters; pitch 1.5 mm; 60° metric profile according to ISO 68-1; 6H hole tolerance according to ISO 965; right-hand; straight flutes for controlled evacuation. Material: ground high-speed steel (HSS), resistant to microchipping and able to maintain edge sharpness. The two-part arrangement according to DIN 2181/2 — starter tap (I) and finishing tap (II) — stabilizes load distribution. Recommended drill diameter: 60.5 mm; using emulsion or active cutting oil improves surface quality and edge life.
- Smooth guidance — sequential use of the two taps reduces torque pulsations and promotes uniform thread formation.
- Extended service life — ground HSS reduces wear and promotes a clean profile.
- Precise fit — tolerance class 6H allows inspection with GO / NO-GO gauges.
- Workflow organization — in assembly practice, repeatability and consistency of operations are facilitated by M62x1.5 Hand Tap Set.
DIN 2181/2, ISO 68-1, and ISO 965 standards ensure compatibility with inspection instruments and predictable results in one-off and small-batch production.
