FAQs
Is this set suitable for stainless steel?
No, this tungsten steel set is intended for softer materials like aluminum, copper, and mild steel.
What does UNF stand for?
UNF stands for Unified National Fine, indicating a specific thread pitch and angle profile.
Does this set include a tap wrench or die stock?
The set includes the tap and the split die; handles or wrenches are generally sold separately.
Can I use this for left-hand threads?
No, this set is specifically manufactured for right-hand thread applications.
How do I maintain the set to prevent rust?
Clean the tools thoroughly after use and store them with a light coating of oil in a cool, dry environment.
Troubleshooting
Threads are rough or torn
Ensure you are using cutting oil and that the tap or die is sharp. Increase the amount of lubrication applied during the cutting process.
The tap is difficult to turn
Back the tap out periodically to break the chips. Check that the pilot hole is correctly sized for the 3/4-16 UNF thread.
Die is not cutting deep enough
Adjust the split die using the set screws to provide a slightly larger diameter initially, then tighten in subsequent passes.

Setup, Compatibility & Care
To set up for internal threading, ensure the workpiece is clamped securely in a vice to prevent movement. Apply steady, perpendicular pressure on the tap wrench. For external threading, use a die stock handle and ensure the rod end is beveled to help the die start straight. Regarding compatibility, this set is specific to 3/4" x 16 UNF threads and should not be forced onto metric or UNC fasteners. After use, clean the teeth of the tap and die with a wire brush to remove metal shavings. Apply a light coating of machine oil before storing the tools in a dry, rust-free container.
