Roughing tap and finishing tap – how much material each removes

Division of work in the 1–2 set

The M60x2 thread is cut into the wall of a hole with a diameter of 58 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.

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 60 mm minus pitch 2 mm gives 58 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 150 mm, or 2.5 times the thread diameter (2.5 x 60 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 M60x2 screw.

M60x2 fine-thread hand taps

Hand Tap M60x2 DIN 2181/2 6H HSS is used to cut precision M60 metric threads with a two-millimeter pitch in steels and metal alloys with tensile strength up to eight hundred megapascals. The two-piece design — starter tap (I) and finishing tap (II) — balances torque and supports axial alignment, resulting in fit accuracy to class six H.

Technical specifications: nominal diameter sixty millimeters; pitch two millimeters; 60° metric profile according to ISO 68-1; hole tolerance class 6H according to ISO 965; right-hand direction; straight flutes for controlled chip evacuation. Material: high-speed steel (HSS), with a ground finish for longer cutting edge life and reduced microchipping. Recommended drill: 58.0 mm; lubrication with emulsion or active cutting oil improves surface quality and extends cutting edge life.

  • Workshop efficiency — consistent operation and repeatable results are facilitated by M60x2 Hand Tap Set.
  • Stable profile formation — two stages of operation reduce torque peaks and improve thread uniformity.
  • Edge protection — ground HSS slows wear and ensures a clean thread contour.
  • Class 6H fit — maintenance of the effective diameter is confirmed by GO / NO-GO gauge checks.

Compliance with DIN 2181/2, ISO 68-1, and ISO 965 ensures full compatibility with measuring equipment and predictable geometry of the resulting threads. In machining practice, the process is supported by M60x2 Hand Tap Set, which maintains dimensional stability in both one-off and short-run production.

Frequently asked questions

The set consists of two taps — a roughing tap and a finishing tap, which guarantee a fully formed thread when used in sequence.

Drill to 58 mm (diameter 60 mm minus pitch 2 mm) to achieve the correct thread engagement in class 6H.

The HSS tool works well in low-carbon steel, aluminum, brass, and other materials with good machinability.
