Roughing tap and finishing tap – how much material each removes

Division of work in the 1–2 set

The M17x2 thread is cut into the wall of a hole with a diameter of 15 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 17 mm minus pitch 2 mm gives 15 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 42.5 mm, or 2.5 times the thread diameter (2.5 x 17 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 M17x2 screw.

M17x2 fine-thread hand taps

Hand Tap M17x2 ISO 529/2 6H HSS is designed to cut precise metric threads with a pitch of two millimeters in structural steels, nonferrous alloys and harder plastics. Its careful construction and stable profile geometry enable a clean, repeatable thread profile in one-off and small-batch machining.

Technical parameters: nominal diameter seventeen millimeters, pitch two millimeters, sixty° profile conforming to ISO 68-1, internal thread tolerance class 6H per ISO 965, right-hand thread. The ground high-speed steel (HSS) version guarantees long cutting edge life and reduces the risk of microchipping. The two-tap design conforming to ISO 529/2 — starter (I) and finisher (II) — equalizes torque and helps maintain axial alignment. In workshop practice, the tapping process is improved by M17x2 Hand Tap Set, which helps maintain the correct working sequence and ensures consistent results across successive passes.

  • Optimal profile formation — the two-stage operation limits torsional vibration and reduces the risk of jamming.
  • Long cutting edge life — precision-ground high-speed steel (HSS) provides longer service life and maintains a sharp cutting edge.
  • Class 6H accuracy — guarantees an ideal fit and maintains profile geometry throughout the full depth of the hole.
  • Process control and organization — a properly matched tap sequence in the Hand Tap Set M17x2 enables consistent machining and easy dimensional inspection.

Compliance with ISO 529/2, ISO 68-1 and ISO 965 ensures full compatibility with inspection equipment and predictable results in production cycles. Combining precision design with the durability of HSS, Hand Tap M17x2 ISO 529/2 6H HSS provides a reliable solution for assembly and workshop operations with high accuracy requirements.

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.

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

High-speed steel (HSS) provides high durability, abrasion resistance, and stable operation even under demanding conditions.
