STI Hand Tap ISO 529 HSS-G - M 30 x 3.5

• Produce internal or external threads as specified by the tool type in the product name.
• Use in machining, maintenance, and fabrication workflows where controlled thread production is required.
• Select by thread designation as stated in the product name: M 30 x 3.5.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition
• Use lubrication suited to the work material and keep the working area clean for stable results.
• Inspect the produced thread with an appropriate method when the application is safety relevant.

Note Clean the functional surfaces after use and store the product protected from contamination.

• Good control during manual thread cutting operations
• Suitable for maintenance and workshop thread production
• Supports controlled alignment and torque application with a tap wrench
• Practical for thread rework and small batch tasks

• Tool life and result depend strongly on lubrication and material condition
• Not intended for high volume production without optimised process control

1. Prepare the workpiece correctly, including core hole or lead in preparation as required.
2. Apply lubrication suitable for the work material and process.
3. Mount the tool in a suitable holder or wrench and ensure straight alignment.
4. Start the thread carefully and maintain stable guidance during engagement.
5. Remove chips and debris as needed so cutting edges remain free.
6. Stop if resistance increases unexpectedly and check alignment and lubrication.
7. After threading, clean the thread and protect the tool for storage.
