VÖLKEL Combined Machine Tap with round shank and square drive 30° Spiral Flute HSSE - M 4 x 0.7
The VÖLKEL Combined Machine Tap is a revolutionary tool that combines the processes of drilling and tapping in a single operation. Thanks to its integrated spiral drill section, you can both drill the core hole and cut the through-thread without having to change the tool. This not only saves time but also increases efficiency. Made from HSSE (High-Speed Steel with Cobalt content), this tool is ideally suited for universal use in materials of medium strength.
What is a Combined Machine Tap?
A combined tap is a multifunctional tool that unites a twist drill and a tap on a single shank. This allows for the creation of a thread in just one work step. The twist drill part drills the core hole to the correct diameter, and the tap part immediately cuts the thread afterward. This tool is exclusively designed for through-threads with a maximum depth of 2 x D (twice the nominal diameter).
The VÖLKEL combined tap is perfectly suited for use in unalloyed and alloyed steels up to 600 N/mm², malleable cast iron, nodular graphite cast iron, copper, brass, aluminum, aluminum-magnesium and zinc alloys, red brass, Elektron, and die-cast zinc. Its use is particularly effective on machines with switchable speeds for drilling and tapping. The feed rate must be adjusted to the respective drilling or tapping operations. Tapping chucks with pressure compensation are not usable.
Step-by-Step Instructions for Use
Follow these steps to create a through-thread in one operation:
- Machine Preparation: Clamp the combined tap securely in a rigid tapping chuck (chucks with pressure compensation are not usable).
- Setting the Speed: Set the switchable speeds on your machine so that the drilling process begins with the correct speed and is automatically adjusted for tapping.
- Drilling: Start the process by drilling the core hole. The tool automatically drills the hole to the correct diameter. Adjust the feed rate accordingly.
- Tapping: Once the drill section has penetrated the material, the tap section immediately begins cutting the thread. The feed rate must also be precisely matched to the thread here.
- Completion: The through-thread is completed in a single, efficient work step.
Frequently Asked Questions (FAQ)
1. What is the main advantage of a combined tap?
The greatest advantage is the significant time saving, as drilling the core hole and cutting the thread happen in a single operation, without having to change the tool.
2. Can I use this tool for blind holes?
No, this tool is exclusively intended for through-threads. For blind holes, where the thread does not go through the entire material, you need a different type of tap.
3. What does HSSE mean?
HSSE stands for "High-Speed Steel with Cobalt". This material is a high-performance high-speed steel alloyed with cobalt. This increases the hardness, heat resistance, and wear resistance of the tool, making it suitable for more demanding applications.
4. What is the maximum threading depth?
The maximum threading depth is 2 x D, which is twice the nominal diameter. This is important to ensure correct function and a long tool life.
5. Which machines are suitable for use?
The tool is particularly useful on machine setups that offer switchable speeds for drilling and tapping. This allows the feed rate to be optimally adjusted to the respective phases of the work process.
