HexTap Type DS - Double ended tap, Multi-Drive Form C HSS-G - UN 2" x 8 | VÖLKEL

HexTap Type DS - Double ended tap, Multi-Drive Form C HSS-G - UN 2 inch x 8

This HexTap Type DS helps with large assembly repair where high torque tapping is required on UN internal threads.

The compact body is useful when surrounding geometry limits swing radius, and the Multi-Drive interface supports firm engagement with suitable drivers.

Application

  • Produce UN internal threads for large fasteners in equipment, transport, and structural builds.
  • Re tap threads that bind due to contamination or slight thread flank damage.
  • Prepare holes for threaded hardware during field repairs.
  • Use where a compact double ended tap reduces handling effort.

Note Match the drive tool to the available clearance and torque requirement, and protect the cutting edges during transport and storage.

Benefits

  • Compact double ended tap supports efficient handling on large assemblies.
  • Multi-Drive interface supports different driver types for confined installation points.
  • Form C chamfer supports controlled entry and stable guidance.
  • HSS-G execution supports repeatable performance in common metallic materials.
  • Supports thread making and thread restoration without complex setup.
Drawbacks
  • Not suitable for materials with high hardness or strong work hardening without testing.
  • Not intended for high speed, high throughput manufacturing environments.

Step by step

  1. Confirm the thread specification and the required thread depth for the job.
  2. Prepare the hole entrance so the tap can locate cleanly.
  3. Secure the assembly to prevent movement during tapping.
  4. Choose a Multi-Drive drive option that fits the torque and access. Technical information HexTap DS as PDF
  5. Lubricate the tool with cutting fluid suitable for the material.
  6. Start the tap with firm alignment to the hole axis.
  7. Cut the thread while clearing chips to avoid overload.
  8. Verify fit with the mating fastener after cleaning.

Frequently asked questions (FAQ)

How do you confirm that this tap matches the thread you need?
Compare the thread designation on the tool with the drawing or the mating fastener. If thread identification is uncertain, check with a gauge before cutting.
How does the double ended design support larger thread work?
It helps you keep the process compact and controlled at higher torque levels. Use stable driving and good lubrication to protect the cutting edges.
How do you choose between different drive options?
Select the drive option that fits the available space and gives stable torque control. Avoid setups that twist the tool axis under load.
What should you do if the tap feels unstable at the start?
Stop and check alignment and hole preparation. A misaligned start can damage the first thread turns quickly.
How do you avoid poor surface finish on the thread?
Maintain alignment and lubrication and keep chips from packing in the flutes. Clean the hole between passes if needed.
How do you handle a thread that still binds after re tapping?
Clean the thread fully and inspect the first turns for deformation. If binding persists, verify the thread designation and consider repair options.
