VÖLKEL Adjustable Tap Wrench Steel Version No. 3: Precision and Power for Your Project

Looking for a robust and versatile tool to cut threads by hand? Then the VÖLKEL Adjustable Tap Wrench Steel Version No. 3 is your ideal partner! It was specially designed to hold square-shank taps, offering you maximum flexibility and stability for manual thread cutting. Made from high-quality steel, this tap wrench guarantees an extremely long service life and excellent resistance to deformation and wear—even with high torque and intensive use.

What is a Tap Wrench and Why Do You Need It?

A tap wrench is an essential hand tool used to manually turn taps (and sometimes reamers or other tools with square shanks) to cut internal threads into a pre-drilled hole. You always use a tap wrench when you are doing the following:

  • Repair work: For recutting or restoring damaged threads.
  • Prototyping and model building: For single parts or where a threading machine is not available.
  • Assembly purposes: For cutting threads in metal, plastic, wood, or other materials.

The Advantages of an Adjustable Tap Wrench

An adjustable tap wrench offers you decisive advantages over fixed tap wrenches:

  • Maximum Flexibility: Thanks to its adjustability, you can hold a variety of different sized taps with just one tap wrench. This saves space in your toolbox and reduces your investment.
  • Secure and Firm Grip: The jaws clamp the square shank of the tap centrally and without play. This prevents the tap from slipping or tilting during the cutting process, which is essential for a precise thread.
  • Optimal Power Transmission: The two handles (with a length of 380 mm on this model) allow you to apply the necessary rotational force evenly and in a controlled manner. This makes cutting easier, especially for larger diameters or harder materials.
  • Controlled Application: You can precisely control the feed and rotational movement when cutting threads by hand, which leads to better thread quality and a longer service life for the tap.

Steel Version for Maximum Durability

The designation as a "Steel Version" is an important quality feature that pays off in practice. Unlike models made of cast iron or other less-resistant materials, this tap wrench is made of high-quality, hardened steel.

This means for you: It is significantly more robust and durable and can withstand higher torques without deforming or breaking. This property is crucial when you are working with tough materials or cutting larger threads where higher forces are involved.

Size No. 3 and Range: How to Find the Right Tap

The specifications No. 3 and the range of 4.9-12 mm are the key figures for choosing the right tap wrench.

  • The No. 3 size classification defines the clamping range of the tap wrench.
  • The range of 4.9 mm to 12 mm is the decisive information for you. It indicates that this tap wrench can hold square shanks with an edge length from 4.9 mm to 12 mm.

Practical Example: An M10 tap often has a 7 mm square, while an M20 tap might have a 12 mm square. Both would fit into this tap wrench without any problems. Smaller taps, like an M5 (with a 4.9 mm square), will also fit.

The overall length (L1) of 380 mm tells you the length of the lever arms. A greater length means more leverage and thus makes cutting easier.

Frequently Asked Questions (FAQ)

What is the difference between a fixed and an adjustable tap wrench?

A fixed tap wrench is designed for a single square shank size, whereas an adjustable tap wrench like this one can clamp a wide range of sizes, providing greater versatility with a single tool.

What does the "No. 3" classification mean?

"No. 3" is a traditional size classification that corresponds to a specific clamping range. For this wrench, it means it is suitable for square shanks from 4.9 mm to 12 mm, which is the most important detail for you to know.

Can this tap wrench be used for other tools besides taps?

Yes. The wrench is designed to hold any tool with a square shank within its 4.9 mm to 12 mm clamping range. This can include small reamers or other specialized hand tools.
