Cleveland C57228 Spiral Point Tap Plug
The Cleveland C57228 is a spiral point tap plug designed for creating internal threads in through-hole applications. Machinists and maintenance technicians use it to produce metric M14x2 threads efficiently. Its high-speed steel construction provides durability for general-purpose threading tasks in steel and non-ferrous materials. The bright uncoated finish suits standard workshop conditions.
M14x2 metric thread size with D7 limit
The decisive specification is the M14x2 thread size combined with a D7 thread limit for a 6H class of fit. This defines the exact pitch diameter tolerance the tap will cut, determining whether the resulting threads meet the required gauge fit for the mating fastener. A different limit or pitch would produce threads that are too tight or too loose for the intended assembly. The 75 percent thread drill size is 12.00 mm.
High-speed steel tap for through-hole threading
The spiral point design pushes chips ahead of the tap, making it suitable for through-holes where chips can escape out the bottom. It requires a pre-drilled hole of the correct diameter and a tapping wrench or machine spindle with reversible drive. The 91.28 mm overall length and 42.07 mm thread length provide reach for deeper holes. It does not suit blind holes where chips must be pulled upward.

Questions about this item
What does the M14x2 thread size mean when I start cutting threads in a real workpiece?
The tap cuts a metric coarse thread with a 14 mm major diameter and 2 mm pitch, producing a 6H class fit when used with a 12.00 mm drill hole.
How does the spiral-point design affect chip flow and the practical depth I can tap?
The spiral point pushes chips ahead of the tap, allowing through-hole tapping up to the 42.07 mm thread length without chip packing.
What shank dimensions and clearance do I need in my tap holder or machine spindle to run this 91.28 mm overall length tool?
The tap follows standard M14 metric shank dimensions; ensure your holder accommodates the 91.28 mm overall length and provides enough reach for the 42.07 mm thread section.
