US PRO 32 Piece Metric Tap And Die Set M3-M12 - US PRO - 2625

The US PRO 32 Piece Metric Tap and Die Set can be used on a variety of materials including steel, aluminum, and cast iron. However, the hardness of the material will affect the cutting process, so use appropriate techniques and cutting oil.

The pitch gauge is used to determine the thread pitch (the distance between the threads) of a screw or bolt. This helps you select the correct tap or die size for your project.

Taper taps have a tapered end and are used to start the thread. Intermediate taps have a shorter taper, used after the taper tap. Plug taps have no taper and are used to finish the thread to the bottom of a blind hole.

Use cutting oil or a suitable lubricant during the tapping or dieing process. Apply the lubricant generously to the tap or die and the workpiece. This helps reduce friction, prevents heat buildup, and improves the quality of the threads.

After use, clean the taps and dies and apply a light coat of oil to prevent rust. Store the set in the provided metal case to protect the tools and keep them organized.

Use a tap extractor tool to remove the broken tap. If the tap is too difficult to remove, consider using a drill bit with the same diameter as the tap to drill out the broken piece, then re-tap the hole with a slightly larger size.

No, this set is designed specifically for metric threads (M3 to M12). It is not suitable for use on imperial or other non-metric thread types.

Ensure the correct size and type of tap or die is used. Apply cutting oil for lubrication and avoid excessive force. If the issue persists, the material might be too hard for the tool, consider a different approach.

Check the tap/die size and ensure it matches the bolt or hole. Use cutting oil and make sure the tap/die is aligned correctly. If the threads are still incorrect, the tool might be worn out.

Ensure the workpiece is secure, use cutting oil liberally, and check for any obstructions. If it's still difficult, try backing off the tool and re-engaging to clear any metal chips.

Ensure all tools are placed in their designated slots within the case. Remove any debris that might be preventing the case from closing properly. Check for damage to the case or tools.
