HexTap Type DS - Double ended tap, Multi-Drive Form C HSS-G - UN 1.1/4 x 8

• Application: producing, restoring, or chasing the thread named in the product title with a threading product
• Select by thread designation, tool type, standard reference, and the working method used in your workshop or maintenance process
• Use the product where thread accuracy, tool guidance, and process control matter more than generic category selection
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Check the designation in the product title, the standard reference, and your application sequence before ordering.

• The product title states the exact thread designation, which reduces selection ambiguity for the threading step.
• The named tool type gives you a defined process direction for cutting, restoring, or chasing the thread.
• The stated standard or execution helps you match the tool to workshop, maintenance, or production logic.
• HSS-G indicates ground high speed steel and points to a ground cutting geometry with a focus on dimensional consistency.

• Thread cutting tools depend on correct hole preparation, alignment, and lubrication to achieve a reliable result.
• A threading tool is limited to the thread system and execution named in the product title.

1. Confirm the thread designation and the tool type named in the product title before you start.
2. Prepare the bore or starting condition according to your process plan and deburr the entry if required.
3. Mount the tool in a suitable holder or machine arrangement and align it with the thread axis.
4. Apply suitable cutting fluid when your material and process require lubrication.
5. Drive the tool with controlled feed and clear chips from the working zone when necessary.
6. Reverse the tool out carefully, clean the thread, and inspect the result with your normal workshop check.

What should you check first before ordering?
Check the thread designation, the tool type, and the standard reference in the product title first. Those three points prevent the most common selection error.

Is this product for cutting, chasing, or holding?
The product type in the title answers that question first. Cutting tools create or restore threads, while holders and guides control mounting and alignment.

Do you need to match the holder type as well?
Yes. A threading tool performs correctly only when the holder concept, drive method, and available access fit the application.

How do you avoid the wrong thread system?
Use the designation in the product title as the main decision point. Metric, unified, Whitworth, pipe, and trapezoidal systems are not interchangeable.

Can you use this product in maintenance work as well as production?
Yes, when the named designation and tool type match the task. The difference is not the category label but the actual process sequence and holder setup.
