Cleveland C60732 #10-32 UNF tap
This Cleveland straight flute hand tap cuts #10-32 UNF threads in a single pass. It is intended for machinists and maintenance technicians who need to create or repair internal threads by hand. The high-speed steel construction provides durability for general-purpose threading tasks in steel and non-ferrous metals.
Plug chamfer and H3 thread limit
The plug chamfer offers a moderate lead-in suitable for through holes and blind holes with adequate clearance. The H3 thread limit produces a class 2B fit, ensuring standard tolerance for nut and bolt assemblies. Four flutes provide balanced chip clearance and cutting stability during manual operation.
Practical limits of UNF hand tapping
Hand tapping requires precise alignment and steady pressure to avoid tap breakage or oversized threads. The 75 percent thread drill size #21 must be used to achieve the correct thread depth and strength. This tap is not suited for high-volume production or materials that exceed the cutting capacity of uncoated high-speed steel.

Questions about this item
Will the #21 drill bit need replacement after repeated tapping of #10-32 UNF threads?
The 75 percent thread drill size #21 is a consumable; its lifespan depends on material hardness and how many holes you cut.
What limits continuous threading with this H3 class 2B tap?
Chip evacuation in the straight flutes is the first constraint; deep or blind holes require frequent back-out to clear swarf.
How much heat builds up when running this high-speed steel tap all day?
High-speed steel resists tempering loss, but sustained cutting without coolant will raise temperatures enough to dull the 4 flutes faster.
