Cleveland C55152 Straight Flute Hand Tap
This Cleveland C55152 is a straight flute hand tap designed for creating Unified National Coarse threads. It suits machinists and maintenance technicians who need to cut internal threads in a variety of materials using hand or powered equipment.
Verify thread size and drill specification
Before ordering, confirm the workpiece requires a 1"-8 UNC thread and that the tap drill matches the 75 percent thread drill size of 22.25 mm. Ensure the application suits a plug chamfer and that the H4 thread limit meets the required class of fit 2B for the joint.
Sustained cutting in high-speed steel with TiN
The high-speed steel body with TiN coating maintains hardness during extended threading operations. The four-flute design evacuates chips steadily to reduce binding in deeper holes, while the 2 1/2 in thread length supports consistent engagement through the full cut.

Questions about this item
Does the Cleveland C55152 tap come with a handle or drill bit, or must those be purchased separately?
The Cleveland C55152 is the tap only. A suitable tap wrench and a 22.25 mm drill bit for the 75 percent thread depth are sold separately.
How do I decide between a plug, taper or bottoming chamfer for a 1"-8 UNC hole?
Choose the plug chamfer on this C55152 for general through-holes or blind holes with enough clearance; it starts easier than a bottoming tap and cuts cleaner than a taper tap.
What does the H4 thread limit mean when I cut 1"-8 UNC threads in steel?
H4 denotes a pitch-diameter tolerance that produces a class 2B fit, giving standard allowance and tolerance for general-purpose fastening in steel.
