Introduction to Thread Cutting Taps
Thread cutting taps are essential tools in machining, used to create internal threads in holes for bolts, screws, and other fasteners. Choosing the right tool from the various types of thread cutting taps ensures precise, clean, and durable threads in different materials.
A tap works by removing material while rotating, cutting the helical groove that forms the thread. The performance, accuracy, and lifespan of each tap depend on its design, flute geometry, and material composition.
Understanding the types of thread cutting taps helps engineers, machinists, and manufacturers optimize productivity and quality.
The 4 Main Types of Thread Cutting Taps
There are several types of thread cutting taps, each engineered for specific materials and hole types. The four primary varieties are: Spiral Flute Taps, Spiral Point Taps, Straight Flute Taps, and Pipe Taps. Understanding their design and purpose ensures you select the right tool for the job.
1. Spiral Flute Taps
Spiral flute taps, one of the most common types of thread cutting taps, feature helical flutes similar to a drill. These flutes lift chips out of the hole during threading, making them ideal for blind holes (holes that do not pass through the material). The spiral design prevents chip packing and reduces the risk of breakage.
They are especially suitable for cutting threads in soft materials such as aluminum and copper alloys. The spiral angle can vary between 15° and 45°, influencing how chips are ejected and how the tap performs in different depths.
2. Spiral Point Taps (Gun Taps)
Spiral point taps, often called “gun taps,” push chips forward rather than pulling them out. This makes them perfect for through holes, where chips can exit from the opposite side. Among the types of thread cutting taps, spiral point taps are known for their strength and durability.
They work exceptionally well with steel and hard materials, providing excellent performance at high speeds. Their cutting edges are designed to minimize friction and extend tool life, which is ideal for production environments.
3. Straight Flute Taps
Straight flute taps are the traditional and simplest types of thread cutting taps. With straight flutes running parallel to the tool axis, they are versatile and suitable for both hand and machine operations. However, because they don’t control chip flow direction, they are best for short-chipping materials such as cast iron or brittle metals.
Straight flute taps provide precise cutting and are often used when working with general-purpose threading operations where chip evacuation is not critical.
4. Pipe Taps
Pipe taps are specialized types of thread cutting taps designed to cut tapered threads, typically for sealing joints in fluid systems. They are commonly used for National Pipe Thread (NPT) or British Standard Pipe (BSP) applications, ensuring leak-proof fits for gas, liquid, and hydraulic systems.
Because of their tapered geometry, pipe taps form a tight mechanical seal as they are threaded into the mating part, making them indispensable in plumbing, oil, and gas industries.
Applications and Material Considerations
Selecting the right types of thread cutting taps depends on several factors: material hardness, hole depth, and desired surface finish. Each tap type is engineered for particular materials and machining environments.
- Spiral Flute Taps: Ideal for soft materials like aluminum, copper, and plastics.
- Spiral Point Taps: Suitable for steels, stainless steel, and tough alloys.
- Straight Flute Taps: Best for cast iron or brittle materials.
- Pipe Taps: Used for sealing applications in pipes and fluid fittings.
For maximum tool performance, proper lubrication, coolant application, and machine settings are essential. Misapplication of types of thread cutting taps can lead to premature wear, thread inaccuracies, and increased production costs.
