US PRO 24PC UNC/UNF Tap And Die Set - 2621

UNC stands for Unified National Coarse, and UNF stands for Unified National Fine. These refer to the thread pitch and are standard thread types.

The tap holder secures the tap while threading holes. The die holder securely holds the die for cutting external threads.

This set is ideal for AF vehicles and machinery.

This set is suitable for use on a variety of materials common in AF vehicles and machinery, such as steel and aluminum. However, it's best to check material compatibility before use.

Identify the thread size and pitch required for your application. The set includes a range of common sizes; match the tap or die to the bolt or hole you are working with.

Use appropriate lubrication, work slowly and steadily, and avoid applying excessive force. Ensure the tool is aligned correctly and back off frequently to clear chips.

Use a cutting oil or a lubricant specifically designed for tapping and die work. This will help reduce friction and prevent damage to the tool and the workpiece.

Store the set in its case in a dry place to prevent rust and damage. Clean and lightly oil the tools before storing them.

Ensure the correct size is used, apply adequate lubrication, and do not force the tool. Back off the tap or die frequently to clear chips.

Ensure the correct tap or die size is used and the tool is aligned properly. Work slowly and carefully, and do not force the tool. If the threads are severely damaged, consider using a thread repair kit.

Apply more lubrication and ensure the tool is aligned correctly. If the tool is still difficult to turn, check for any obstructions or debris in the hole or on the bolt.
