Cleveland C55395 Spiral Point Tap

The Cleveland C55395 is a spiral point tap designed for threading 1/2-20 UNF holes in through-hole applications. It suits machinists and maintenance technicians who need reliable thread production in steel or similar materials.

Check thread specs and toolholding

Verify the required thread size is 1/2-20 UNF with a 2B class of fit before ordering. Confirm your setup can accommodate a 3 3/8 in overall length and a 1 21/32 in thread length. Ensure the 75 percent thread drill size of 11.40 mm matches your prepared hole.

Replaces worn H3 limit taps

This tap replaces an H3 limit spiral point tap that has dulled or chipped, restoring consistent 3-flute cutting action. The upgrade is worth it when thread quality drops or tap life falls below expected intervals for the same material and conditions.

Questions about this item

Does the tap come with a handle or drill bit, or do I need to buy them separately?

The package contains only the spiral point tap itself; a tap wrench or compatible holder and the 11.40 mm drill for the 75 percent thread must be purchased separately.

When would I choose the H3 limit over another limit for a 1/2-20 UNF hole?

H3 is the standard limit for a class 2B fit in 1/2-20 UNF; select it for general-purpose threading unless the drawing specifies a tighter or looser limit.

What does the 3 3/8 inch overall length mean when the tap is in a drill press or hand wrench?

The 3 3/8 inch length gives enough reach for through-holes up to about 1 21/32 inch deep while keeping the shank supported in a standard chuck or tap holder.
