Cle-Line C00796 Spiral Point Tap
The Cle-Line C00796 is a high-speed steel spiral point tap designed for creating internal threads in through-holes. It features a 7/16-14 UNC thread size with a plug chamfer and three flutes for efficient chip evacuation. The bright, uncoated finish suits general-purpose machining applications. Machinists and maintenance technicians use it for reliable thread production in steel and other ferrous materials.
Replaces worn or damaged taps for 7/16-14 UNC
This tap restores the ability to cut precise Class 3B threads when an existing tool has dulled or broken. The spiral point design pushes chips ahead of the cut, reducing torque and extending tool life compared to standard hand taps in through-hole work. The upgrade is worthwhile when thread quality or tapping speed becomes a bottleneck in repetitive operations.
Suits machinists cutting 7/16-14 UNC through-holes
The H3 thread limit and 75 percent thread drill size U requirement align with standard fit specifications for this diameter. It is not suited for blind holes where chips cannot escape forward, nor for materials requiring coated tooling for heat resistance. Users needing different thread forms, limits, or flute counts should select an alternative tap.

Questions about this item
What drill size does the 7/16-14 UNC tap require for a 75 percent thread?
Use a size U drill to produce the correct hole before tapping with this tool.
How should the spiral point tap be aligned when starting the cut?
Start the tap square to the workpiece and apply steady forward pressure so the spiral point pushes chips ahead without binding.
When will the high speed steel cutting edges need to be replaced?
Replace the tap when thread quality degrades or the flutes show visible wear after repeated use in steel.
