Cleveland C59117 Spiral Point Tap
The Cleveland C59117 is a spiral point tap designed for creating internal threads in through-hole applications. It suits machinists and maintenance technicians who need reliable thread cutting in ferrous and non-ferrous metals. The plug chamfer style helps start threads cleanly in a variety of workshop tasks.
1/4"-20 UNC thread capacity
This tap cuts a 1/4 inch diameter thread with a 20 threads per inch Unified National Coarse pitch. The two-flute high speed steel construction provides adequate chip clearance for through holes up to the tool's overall length. It runs out when material hardness exceeds the capability of uncoated high speed steel or when blind-hole tapping is required.
Right-hand high speed steel tooling
The bright uncoated finish works with standard tap holders and wrenches for right-hand thread cutting. High speed steel composition allows resharpening to extend service life in a maintenance environment. The tool requires appropriate cutting fluid and correct alignment to prevent tap breakage during operation.

Questions about this item
Will the 1/4"-20 UNC spiral-point tap cut cleanly in the same high-speed steel workpieces I already machine with older taps?
The tap is made from high-speed steel with a bright uncoated finish and a right-hand spiral-point design that pushes chips ahead of the cut, so it behaves like a standard plug tap in the materials you already run.
How can I confirm the C59117 is cutting true threads after I clamp it in my tap holder?
Run the tap to the full 6 in overall length in a test hole, then check the threads with a 1/4"-20 UNC go/no-go gauge; a clean pass on the go gauge and stop on the no-go gauge shows the tap is cutting to spec.
Does the package include only the C59117 tap, or are a tap wrench and cutting fluid also supplied?
The box contains the single 2-flute spiral-point tap; a tap wrench, cutting fluid and any thread gauges must be purchased separately.
