Cleveland C58584 Spiral Flute Tap

The Cleveland C58584 is a spiral flute tap designed for creating 3/8-24 UNF internal threads in through-hole and blind-hole applications. It suits machinists and maintenance technicians who need reliable thread production in ferrous and non-ferrous metals using standard tool holders.

Capacity and headroom for 3/8-24 UNF threads

This tap produces a 3/8 inch diameter thread with 24 threads per inch to a Class 2B fit using an H3 thread limit. The 3/4 inch thread length and 75 percent thread drill size of 8.50 mm define the engagement depth and core-hole preparation required for full thread form.

Three-flute high-speed steel construction

The bright uncoated high-speed steel body features three flutes that evacuate chips efficiently during bottoming operations. Right-hand thread direction and an overall length of 2 15/16 in provide compatibility with conventional tapping equipment and standard workholding setups.

Questions about this item

Will the 3/8-24 UNF thread size match the existing holes in my older fixture?

The tap cuts a 3/8-24 UNF thread with a 2B class of fit, so it will match holes threaded to the same standard.

How can I confirm the tap is cutting correctly after I start the hole?

Check that the chips curl upward and evacuate cleanly through the three spiral flutes, producing a smooth 3/8-24 UNF thread to the full 3/4 in thread length.

Does the package include the 8.50 mm drill bit needed for the 75 percent thread?

The box contains only the spiral flute tap; the 8.50 mm drill bit must be purchased separately.
