Whether you're searching for a durable tap with thread for stainless steel, a high-accuracy threaded tap connector, or the best taps for cutting threads in production environments, Cutwel has the solution - in stock and ready for next-day UK delivery.
In the cutting industry, a thread tap is a precision tool used to create internal threads inside a pre-drilled hole, allowing bolts, screws, or threaded components to be securely fastened into a material. It’s one of the most common tools in metalworking, engineering, and manufacturing, particularly in CNC machining, maintenance, and fabrication.
Thread taps can be used in both manual and machine applications, and their design often reflects that purpose.
A thread tap cuts grooves (called threads) on the inside wall of a cylindrical hole. These grooves match the threads of a corresponding fastener (e.g., a screw or bolt), creating a mating threaded connection. The process is known as tapping.
Machine taps are best suited for automated, high-volume production, delivering efficiency and consistency. In contrast, hand taps provide greater control and adaptability for manual threading applications.
Recognising the advantages and ideal applications of each tap type helps ensure you select the right tool for your specific threading needs.

A machine tap is a type of thread tap specifically designed to cut internal threads in a hole using machine tools like a CNC machine, drill press, tapping arm, or lathe.
Unlike manual taps, which are turned by hand, machine taps are optimised for automated, high-speed, and high precision tapping in production or engineering environments.
Cutwel’s machine taps range has been curated to cover every thread form, material type and application, including:
Spiral point taps are a type of machine tap specifically designed for cutting internal threads in through holes.
They are one of the most popular types of taps used in CNC machining and high-speed production environments because of their efficiency, chip control, and suitability for long-threaded holes.
Spiral flute taps are a type of machine tap designed specifically for threading blind holes, the holes that do not pass through a part.
Unlike spiral point taps, which push chips forward, spiral flute taps pull chips back out of the hole to prevent jamming and ensure a clean finish, thanks to their helical flute geometry.
These taps are ideal for situations where chip evacuation is critical, especially in softer or ductile materials that produce long or stringy chips.
Straight flute taps are the most traditional and versatile type of threading tap. Featuring straight flutes, they are primarily used for cutting internal threads in a wide variety of materials, especially short-chipping ones like cast iron, brass, or brittle alloys.
They are suitable for both blind holes and through holes, although chip evacuation is not as efficient as with spiral taps. Due to their simplicity and strength, straight flute taps are best for short run or hand tapping applications, particularly in cast iron or non-ferrous materials.
Forming taps (also called roll taps) are used to create internal threads by cold forming the material, rather than cutting it. Instead of removing material like traditional cutting taps, they displace the metal to form the thread shape.
These taps displace material rather than cut it, producing stronger threads and excellent surface finishes. It’s chipless tapping for ductile materials, making it clean, efficient, and ideal for high-speed or automated machining.
In the cutting and threading industry, performance grades refer to how well a thread tap performs under specific conditions, such as speed, tool life, material compatibility, and application type.
You can choose general-purpose machine taps for everyday materials or material-specific performance taps that are engineered to excel in more complex materials like stainless steel, aluminium or titanium.
Performance grades help you select the right thread tap based on your application, material, machine setup, and required productivity.
A machine tap set is a collection of multiple machine taps grouped by size, thread form, or tap type, designed to provide a convenient, versatile solution for threading tasks in workshop, industrial, or CNC settings.
These sets typically include a range of taps for common thread sizes and may be tailored for specific materials or thread standards.
Machine tap sets are ideal for engineers, machinists, and maintenance professionals who need ready access to a selection of threading tools for various jobs.
A coated tap is a type of thread tap that has a thin protective layer applied to its surface to enhance performance, durability, and wear resistance.
These coatings are typically made from advanced ceramic-based materials like TiN and TiAlN and are applied using PVD (Physical Vapour Deposition) or CVD processes, especially in tough or abrasive materials.
Coated taps are widely used in high-speed machining, difficult materials, and high-volume production, where tool life, heat resistance, and chip control are critical.
A thread form defines the shape, angle, pitch, and profile of a screw thread. A machine tap must be matched to the correct thread form for your application to ensure compatibility and performance. You can choose from Metric Coarse/Fine, UNC/UNF, BSP, NPT, Whitworth, Trapezoidal and more.
