Cleveland C96126 Spiral Point Tap

This Cleveland C96126 spiral point tap cuts 5/8-11 UNC threads in through-holes. The cobalt construction with black oxide finish resists wear during repeated threading operations. Three flutes provide chip clearance while the spiral point pushes chips ahead of the cutting edges. Right-hand threading matches standard fastener conventions.

Machinists cutting unified coarse threads

Suited for professionals producing 5/8 inch diameter threads with 11 threads per inch in steel or alloy materials. The 2B class of fit meets general industrial requirements for assembly. Not intended for blind holes where chips cannot escape forward, nor for left-hand thread applications. Buyers needing different thread forms or diameters must select alternative tooling.

5/8-11 UNC thread specification

The 5/8-11 UNC designation determines compatibility with matching fasteners and drilled holes. A 75 percent thread drill size of 13.60 mm prepares the correct hole diameter. Thread length measures 2 3/32 inches within an overall length of 4 21/64 inches. Thread limit 2B ensures proper engagement with standard nuts and bolts.

Questions about this item

Does the Cleveland C96126 tap come with a matching 13.60 mm drill bit, or must I buy it separately?

The tap is sold alone; a 13.60 mm drill for the 75 percent thread is not included and must be purchased separately.

When should I choose the 5/8-11 UNC 2B cobalt tap over a different thread limit or material?

Select this 2B class-of-fit cobalt tap for general-purpose through-hole threading in tougher steels where the black oxide finish adds wear resistance.

What does the 4 21/64 in overall length mean when the tap is in my drill press or tap wrench?

The 4 21/64 in overall length with a 2 3/32 in thread portion gives enough reach for standard through-holes while keeping the shank short enough for common tap holders.
