Cleveland C57192 Spiral Point Tap

The Cleveland C57192 is a spiral point tap made from high speed steel with a bright uncoated finish. It cuts a right-hand UNC thread sized 7/16 in -14 and has three flutes for chip evacuation. The thread limit is H3 for a class 2B fit and the overall length is 3 5/32 in.

Machinists cutting through-holes in steel

This tap suits machinists who need to produce through-holes in steel using a plug chamfer. The spiral point design pushes chips ahead of the cut so it is not intended for blind holes where chips must be lifted out. Buyers who need a bottoming chamfer or a tap for blind holes should look at a different tool.

Thread size 7/16 in -14 UNC

The single specification that decides fit is the thread size of 7/16 in -14 UNC with an H3 limit for a class 2B fit. If the drawing calls for a different diameter pitch or class of fit this tap will not produce the correct thread.

Questions about this item

How do I confirm the 7/16-14 UNC tap is cutting correctly after setup?

The spiral point should push chips ahead of the cut. Check that threads match a 2B class of fit with a thread gauge and that the hole uses a U drill size for 75 percent thread engagement.

What comes with the C57192 tap and what must I supply?

The box contains the high-speed steel spiral point tap with three flutes, bright finish, 3 5/32 in overall length and 1 7/16 in thread length. You must provide the U-size drill bit, tapping fluid and a tap wrench or holder.

Which thread limit should I choose for a standard 7/16-14 UNC hole?

The H3 limit supplied with this tap is the standard choice for a 2B class of fit in a 7/16-14 UNC thread. Select it when the design calls for normal tolerance without oversize or undersize allowance.
