Threading Taps

Choose the right threading tap for clean, accurate threads

A good threading result starts with the right tap for the hole type, material and working method. Here you can compare machine taps for through holes and blind holes, fine thread taps, G-thread taps, forming taps, extra-long taps and practical tap-drill sets. The range also includes tap chucks, adapters and holders for both machine and hand use.

For everyday workshop work, the most important choice is whether chips must exit forward or be lifted out of the hole. Through-hole taps are designed for efficient chip evacuation in open holes, while blind-hole taps are better suited when chips must be directed back out of the hole. If you work with stainless steel, alloy steel or demanding production runs, coated and powder-steel options can offer better wear resistance and longer tool life.

Tap types in the range

Through-hole taps

Through-hole machine taps are a practical choice when the hole goes fully through the workpiece. Spiral point and straight flute models are commonly used for reliable chip flow and efficient tapping in steel, stainless steel and non-ferrous materials.

Blind-hole taps

Blind-hole taps are designed to manage chips upward from the bottom of the hole. Spiral flute models are especially useful when you need cleaner chip evacuation and lower risk of chip packing in deeper or more demanding holes.

Fine thread and G-thread taps

When the application calls for metric fine threads or pipe-style G threads, it pays to choose a tap made specifically for that thread form. This helps maintain thread accuracy, fit and process reliability, especially in repair, assembly and fluid-related applications.

Forming taps

Forming taps create threads without cutting chips. They are a strong option for suitable materials when you want improved thread strength, cleaner operation and longer tool life in repetitive production.

How to select the right tap

Start with four basic factors:

1. Hole type: through hole or blind hole
2. Thread standard: metric, metric fine or G thread
3. Material: steel, stainless steel, alloy steel, aluminium or non-ferrous material
4. Tooling method: hand tapping, drill press, magnetic drill or tapping chuck setup

Size range is broad, from small M2-M4 taps up to larger workshop sizes such as M16, M20 and above in selected models. Product pages show the exact thread sizes, DIN standard and tolerance details, so it is worth checking the product data for the live size availability and stock status before ordering.

Tap holders, chucks and complete sets

The right holder improves alignment, torque control and thread quality. In addition to taps, the selection includes reversible tap chucks, tapping chuck sets, Weldon adapters, ratchet tap holders, die stocks and collet sets. These are useful when building a complete tapping setup for a mill, drill, magnetic drill or bench work.

If you need a ready-made starter solution, tap-drill sets combine the essential sizes in one package and help speed up workshop preparation.

NOVA Pro tools for threading work

For threading work, {brand:11|NOVA Pro} is relevant as a tooling and consumables brand. NOVA Pro offers practical tap options for through-hole and blind-hole applications, including straight flute and spiral flute HSS-Co models in common metric sizes. This makes it easier to buy both the tap and other startup tooling for metalworking from one place.
