Built from high speed steel with an oxide finish, it features a plug chamfer for use in both through-hole and blind-hole threading applications. The 4-flute straight-flute geometry provides stability and chip control during manual tapping operations. With a thread length of 1.09 inches and an overall length of 3.813 inches, this tap fits standard tap wrenches and is sized for production and maintenance threading work. It carries a Class 2B fit and H3 thread limit for controlled tolerance output. Machinists, tool-and-die makers, and maintenance technicians use this tap in job shop and field service settings.\u003c\/p\u003e\u003cp\u003eThe C56028 is suited for threading operations in cast iron, stainless steel, and steel. The plug chamfer — typically 3 to 5 threads of lead — makes it appropriate as a starting tap for through-holes or as the primary tap in blind holes with adequate thread runout clearance. The straight-flute design performs best when chips can be managed manually or with cutting fluid. This tap is part of the Cleveland Series 1002BO and is intended for hand tapping applications where torque is applied through a standard tap wrench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-11 UNC right-hand thread, Class 2B fit, H3 thread limit for consistent tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in ferrous materials including cast iron and stainless steel\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces friction and provides corrosion resistance during cutting and storage\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design provides rigidity and even chip distribution in hand tapping\u003c\/li\u003e\n\u003cli\u003ePlug chamfer supports both through-hole and blind-hole threading\u003c\/li\u003e\n\u003cli\u003e1.09-inch thread length on a 3.813-inch overall body fits standard hand tap wrench drives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for hand tapping applications in cast iron, stainless steel, and steel workpieces requiring a 5\/8-11 UNC Class 2B right-hand internal thread.
