Cleveland C55126 Straight Flute Tap 3/8-24 UNF

This Cleveland C55126 is a straight flute tap designed for cutting 3/8 inch UNF threads with a 24 threads-per-inch pitch. It features a plug chamfer, four flutes, and a TiN coating on high speed steel. The thread limit is H3 for a class 2B fit.

Check thread size and drill specification

Verify that your workpiece requires a 3/8-24 UNF thread before ordering. The recommended drill size for 75 percent thread engagement is 8.50 mm. Ensure your tapping equipment can accommodate the 2 15/16 inch overall length and right-hand cutting direction.

Replaces worn or uncoated 3/8-24 taps

This tap upgrades from dull or uncoated high speed steel tools when thread quality or tool life becomes an issue. The TiN coating reduces friction and extends sharpness in repetitive operations. The jump is worth it when cutting harder materials or when consistent class 2B fits are required.

Questions about this item

Does the tap arrive with a handle or drill bit, or must I supply my own?

The box contains only the straight-flute tap; a tap wrench or compatible driver and the 8.50 mm drill for the 75 percent thread must be purchased separately.

What distinguishes the H3 limit from other limits for a 3/8-24 UNF thread?

H3 selects a 2B class of fit that is tighter than H1 or H2, giving closer tolerance on internal threads for precision assemblies.

How does the 2 15/16 in overall length affect reach in a blind hole?

The 2 15/16 in overall length with a 3/4 in thread portion provides enough shank clearance for standard through-holes while the plug chamfer starts threads cleanly in blind holes.
