Cleveland #12-24 UNC spiral point tap
The Cleveland 86212 is a spiral point tap designed for creating internal threads in through-holes. It features a #12-24 UNC thread size with a 2B class of fit and three flutes for efficient chip evacuation. The cobalt construction with black oxide finish provides durability for general-purpose threading tasks.
Suited for through-hole threading in metal
This tap suits machinists and maintenance technicians cutting new threads or cleaning existing ones in through-hole applications where chips can be pushed ahead of the tool. It is not suited for blind-hole work where chips must be pulled upward, nor for users requiring a taper or bottoming chamfer instead of the plug style provided.
Handles #12-24 UNC threads
The tap comfortably produces #12-24 UNC threads using a 4.45 mm drill size for 75 percent thread engagement. Its thread length of 1 1/16 in and overall length of 3 5/32 in define the reach available. It runs out when a different thread size, pitch, or class of fit is required, or when a blind-hole geometry demands a different flute configuration.

Questions about this item
What size drill bit do I need before using this #12-24 UNC tap?
Use a 4.45 mm drill bit for 75 percent thread engagement before tapping.
Will this 3-flute cobalt tap cut threads in my existing steel workpieces?
Yes, the cobalt construction with black oxide finish handles general steel tapping tasks.
How do I verify the threads match the 2B class of fit after tapping?
Check with a #12-24 UNC 2B thread gauge; the go gauge should enter fully and the no-go should not.
