Cleveland C64133 Pipe Tap Overview

The Cleveland C64133 is a pipe and conduit thread tap designed for creating internal NPSF threads in metal workpieces. It suits maintenance technicians and machinists who need to repair or produce 1/2"-14 pipe threads using a standard right-hand cutting action.

NPSF Thread Standard Limits

The tap cuts straight NPSF threads that seal mechanically rather than by taper interference, so a compatible sealant or gasket is required for pressure-tight joints. Its 75 percent thread drill size of 18 mm defines the maximum core diameter you can start with before tapping.

Four-Flute Chip Management

Four straight flutes provide multiple cutting edges and chip evacuation paths, which reduces loading in ductile materials and improves finish on through-holes. The design is less suited to deep blind holes where chip packing can stall the tap.

Questions about this item

What does the 1/2"-14 NPSF size mean for the threads I will cut?

It cuts a 1/2 inch nominal pipe thread with 14 threads per inch to the NPSF standard, producing a straight internal thread for dry-seal connections.

How does the 4-flute design affect chip removal when tapping by hand?

Four flutes give more cutting edges for a smoother finish, but the smaller flute space means you must back out frequently to clear chips in deep holes.

What does the 75 percent thread and 18 mm drill size tell me about the hole I must drill?

Drill the hole to 18 mm diameter; that size yields roughly 75 percent thread height, which balances tap life and thread strength for this NPSF tap.
