Cleveland C57022 Spiral Point Tap
This Cleveland C57022 Spiral Point Tap cuts internal #1-64 UNC threads in through-holes or deep blind holes. The spiral point design pushes chips ahead of the flutes for smoother cutting action. It is suited for machinists and maintenance technicians producing Class 2B fits in steel or non-ferrous materials.
UNC thread standard limits
The #1-64 UNC thread form defines a very fine pitch that restricts use to small-diameter fasteners. A 75 percent thread depth requires a 1.45 mm drill size to prepare the hole correctly. The H2 thread limit and 2B class of fit control the allowance and tolerance for standard assembly.
High speed steel construction
Bright uncoated high speed steel provides hardness and wear resistance for general-purpose threading. Two flutes give adequate chip space while maintaining cross-sectional strength. The 1 11/16 in overall length with a 3/8 in thread length fits standard tap holders and allows reach into typical workpieces. Right-hand cutting direction matches conventional tooling setups.

Questions about this item
Should I choose the #1-64 UNC size or another thread specification?
Select this tap when the job calls for a #1-64 UNC thread; the H2 limit and 2B class of fit match standard requirements for that size.
What does the 75 percent thread drill size of 1.45 mm mean when I am cutting threads?
Drill the hole to 1.45 mm before tapping; this produces a 75 percent thread depth that balances strength with reduced cutting torque.
How does the spiral point design affect chip flow in a through hole?
The spiral point pushes chips ahead of the tap, making it well suited for through holes where chips can exit freely.
