Hand Tap Taper ISO 529 Form A HSS-G - BA 7 x 52.92

• for manual threading, to start the thread securely and prepare it for the subsequent cutting stages
• for servicing, maintenance and single-part production with direct control of the tool
• for cutting new threads, reworking and controlled thread cleaning, depending on the condition of the internal thread
• Process: manual or assisted drive, depending on your tool holder and machine configuration
• Use: thread cutting, thread chasing and thread cleaning, depending on the condition of the thread

Note Guide the hand tap straight and without lateral loads to prevent the cutting edges from jamming.

• taper tap with a clearly defined role in the hand tapping process
• ISO 529 and HSS-G make technical identification within your tool inventory easier
• the BA 7 x 52.92 thread designation helps you select the correct tool for the component and mating thread
• available individually when only one cutting stage needs to be replaced or added

• as an individual tool, it does not replace a complete set when several cutting stages are required for a controlled hand tapping process

1. Check the thread designation, cutting stage and workpiece material before use.
2. Prepare the tapping hole, deburr it and clamp the workpiece securely.
3. Secure the tool in a suitable holder and align it perpendicular to the workpiece.
4. Use a suitable cutting lubricant and apply steady torque.
5. Regularly relieve the load on the tool and keep the working area clear of chips.
6. Clean the thread after the operation and check the fit.
7. Clean the tool after use and store it protected from damage.

When should you use this particular cutting stage?

Use the taper tap when this process step matches the condition of your thread. A taper tap is intended for starting the thread, a second tap for the intermediate cut and a bottoming tap for the final thread form.

Can you use the tool on its own?

Yes, this is possible for reworking or defined individual operations. For cutting a complete new thread, a matched set is often the safer choice.

What should you check before ordering?

Check the BA 7 x 52.92 thread designation, standard, material specification and cutting stage. These details must match the drawing, component and your existing tool inventory.

Why is tool guidance important?

Misalignment places stress on the cutting edges and thread flanks. Straight guidance and even pressure improve the fit and reduce the risk of breakage.

When is a thread gauge useful?

A thread gauge is useful when the thread must be assessed according to an inspection plan and tolerance requirements rather than only checked with a screw.

Where can you find technical basics on hand taps?

Further guidance is available in the Technical Information on Hand Taps PDF.

Is help available for inch threads?

For inch threads, it is important to distinguish clearly between thread systems and pitches. The Inch-mm Conversion Table PDF helps with technical identification.
