Hand Tap Bottoming ISO 529 Form C HSS-G - M 56 x 5.5

• Cut internal threads in drilled holes for fasteners, fittings, and mechanical assemblies.
• Use in mechanical engineering, metal fabrication, and maintenance work where controlled threading is required.
• Start the tap square to the hole to reduce risk of cross starting and uneven flank load.
• 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 For consistent results, deburr the entry and keep the cutting area clean during use.

• Controlled internal thread cutting with direct process feedback
• Suitable for repair work, prototyping, and general workshop machining
• Supports repeatable thread fit when the pre hole and alignment are correct
• Applicable across maintenance and production environments

• Not suitable for brittle or abrasive materials without adapted cutting strategy and tool choice.
• Manual or guided threading can be slow for high throughput applications.

1. Prepare the hole with a correct core diameter and a clean entry chamfer.
2. Secure the workpiece and align the tool square to the hole axis.
3. Apply suitable cutting lubricant for the material and process.
4. Start the tool with controlled torque until it is guided by the thread form.
5. Advance with steady turns or a guided feed while keeping alignment constant.
6. Withdraw the tool at intervals and clear chips from the flutes.
7. Continue until the required thread depth is reached, then remove the tool fully.
8. Clean the thread and check fit with a matching screw or gauge.
