Do you need a precise and reliable tool for cutting internal threads? Then this DIN 352 Form C 35° SP HSSE Single Tap - M 10 x 1.5 is exactly the right choice for you. It's your versatile partner for general use in various materials and application areas.

What is a single tap and how do you use it?

A single tap (also known as a hand tap or bottoming tap, depending on context) is a tool used to cut an internal thread into a pre-drilled hole. Unlike multi-part tap sets which consist of a taper, plug, and bottoming tap, a single tap completes all steps in one operation. This makes it particularly efficient and easy to handle.

How to use it:

1. Prepare the hole: First, drill a pilot hole with the appropriate diameter. For an M 10 thread, you typically need a pilot hole diameter of 8.5 mm. The quality of the pilot hole is crucial for the quality of the subsequent thread.

2. Insert the tap: Insert the tap straight into the pilot hole.

3. Thread cutting:

   • Manual use: If you're working manually (e.g., with a tap wrench), turn the tap carefully and evenly into the material. Make sure to regularly turn it back a quarter turn to break the chips and facilitate the cutting process. Use a suitable cutting oil to reduce friction and extend the tool's lifespan.

   • Machine use: For machine applications (e.g., with a tapping machine or a drill press with tapping attachment), the rotational speed and feed rate are crucial. The machine guides the tap precisely and ensures a consistent thread.

Where do you use this tap?

This single tap is particularly versatile and is excellently suited for:

• Easily machinable materials up to 900 N/mm²: This includes a wide range of materials that are easy to work with.

• Unalloyed and low-alloy steels: Perfect for common steel types used in mechanical engineering and construction, as well as in crafts.

• Blind holes: Specifically for holes that do not go completely through the workpiece (see explanation below).

• Manual and machine use: Its robust construction and material composition allow you to use it both manually and in automated processes.

Explanation of the standard and designations:

• DIN 352: This German industrial standard defines the dimensions, tolerances, and requirements for taps for metric ISO threads. It ensures that taps are standardized and of high quality.

• Metric ISO thread DIN 13: This is the thread type this tap cuts. Metric ISO threads are the most widely used threads worldwide and are characterized by a 60° profile.

• Form C 35° SP: This describes the chamfer form of the tap:

  • Form C: Means a chamfer of 2 to 3 thread pitches. This is the most common form for universal use and offers a good combination of cutting ability and stability.

  • 35° SP (Spiral Point): The "Spiral Point" directs the chips forward through the hole during cutting. This is particularly advantageous for blind holes, as the chips do not remain in the hole, thus preventing clogging or damage to the tool. This is the main difference from other chamfer forms such as:

    • Form A (taper): Very long chamfer (approx. 6-8 pitches), also directs chips forward, but less aggressively. More suitable for through holes.

    • Form B (plug): Short chamfer (approx. 4-5 pitches), also for blind holes, but less efficient chip evacuation than Form C SP.

    • Form D (spiral flute): Has helical flutes that push chips backward, i.e., out of the blind hole. Ideal for deep blind holes in tough materials.

• HSSE (High Speed Steel-E / at least 5% Cobalt content): The material of the tap.

  • HSS (High Speed Steel): Is a high-speed steel known for its high hardness and wear resistance at elevated temperatures.

  • HSSE (High Speed Steel with Cobalt): Means that the HSS material contains at least 5% cobalt. Cobalt increases hot hardness, which means the tap retains its hardness and cutting ability even at higher temperatures. This is particularly important when machining tougher or more abrasive materials and at higher cutting speeds. It leads to a longer tool life.

• Tolerance ISO 2 / 6H:

  • ISO 2: Represents a medium tolerance class that ensures a good fit for general applications.

  • 6H: Is the international tolerance class for internal threads. The "6" refers to the tolerance quality (the smaller the number, the tighter the tolerance), and "H" indicates that the lower deviation of the thread is equal to the nominal size, allowing for an easy fit.

Blind hole vs. Through hole:

It's important to know the difference between a blind hole and a through hole, as this affects the choice of tap:

• Blind hole: A hole that does not go completely through the workpiece. It ends blindly within the material. When tapping blind holes, chips must be efficiently removed to prevent clogging of the tap and damage to the thread. Our tap with Form C 35° SP is ideal for this, as it pushes the chips forward.

• Through hole: A hole that goes completely through the workpiece. Here, chips can exit at the end of the bore, which makes chip evacuation less critical. Taps with straight flutes, which remove chips sideways, are also suitable for through holes.
