Cleveland #6-32 Spiral Flute Tap
This Cleveland C58532 spiral flute tap cuts #6-32 UNC threads in a right-hand direction. The high-speed steel body has a bright uncoated finish and features two flutes for chip evacuation. It is designed for general-purpose threading tasks where a plug chamfer is required. The thread limit is H3 with a Class 2B fit.
Sustained cutting performance
The spiral flute geometry pulls chips away from the cutting zone during continuous operation. This reduces clogging compared to straight-flute designs when threading deeper holes. The high-speed steel construction maintains hardness at elevated temperatures generated by prolonged use. Two flutes provide a balance between chip space and tool rigidity.
Practical limits of UNC threads
The tap produces threads to a 75 percent thread depth using a #36 drill size. The thread length is 3/8 inch within an overall length of 2 inches. UNC coarse pitch limits the number of threads per inch to 32 for this diameter. Class 2B fit provides standard tolerance for nut and bolt assemblies.

Questions about this item
Does the H3 thread limit on this #6-32 UNC tap affect cutting force or heat during long production runs?
The H3 limit and 2-flute design balance chip clearance and strength, keeping cutting forces moderate in typical steel applications.
What size drill bit must I already have to prepare holes for this #6-32 UNC tap?
A #36 drill bit is specified for 75 percent thread engagement before tapping.
Will this right-hand #6-32 tap work in a vintage tap wrench that only accepts square shanks?
The tap follows standard industry shank dimensions for its size, so it fits common adjustable tap wrenches.
