Threading Tools

Threads usually come at the very end of the routing, when a part already carries hours of machining. That is exactly why a broken tap hurts so much.

Gühring is known for long-standing expertise in taps and threading tools. Mentor Mühendislik supplies Gühring taps, thread mills and WIDIA thread turning inserts in Adana. We choose the safest threading method for your hole type, material and machine together with you.

Types of Threading Tools

Spiral Flute Taps

Helical flutes carry chips up to the hole entrance; the go-to for holes with a closed bottom.

Spiral Point Taps

Drive chips ahead of the tap and out of the exit; open holes allow high speeds.

Forming Taps

Cold-form the thread instead of cutting it; no chips and a work-hardened, stronger thread in ductile steels and aluminium.

Thread Mills

Several diameters with one tool, low breakage risk, safe in difficult materials.

Thread Turning Inserts

Lathe threading on shafts and in bores.

Tapping Chucks

Rigid or floating clamping to match your machine’s tapping cycle.

Applications

How to Choose the Right Tool

Check the hole bottom

Closed or open at the far end? That decides how the tap must clear chips.

Define the thread standard

Metric, fine metric, inch or pipe thread and tolerance class.

Verify the pre-drill size

Cutting and forming taps need different pre-drill diameters; the wrong size is a top cause of breakage.

Set holding and parameters

Synchronous tapping, the right holder and speed for safe threading.

Frequently Asked Questions

Why do taps break?

Most broken taps can be traced back: the drill size, chips trapped in a closed hole, a program that goes too deep, tapping dry, or a hole and tap that are not on one axis. Our blog has a seven-point checklist.

When should I use a forming tap?

In ductile materials such as aluminium and low/medium carbon steel, forming taps produce no chips, give stronger threads and have a low breakage risk. Brittle materials like cast iron need cutting taps.

Isn’t thread milling slower than tapping?

It can take longer per thread, but low breakage risk, several sizes from one tool and adjustable thread tolerance make it the choice for expensive parts and difficult materials.

Which tapping chuck should I use?

If your machine supports synchronous tapping, rigid or micro-compensating holders are suitable. If not, you need an axially compensating tapping chuck.
