AWWA Water Main Drill Tap for Cast Iron Pipe and Ductile Iron
Product Overview
AWWA Tapping Competition-winning teams have relied on the Reed DT75 drill tap for over 25 years. This water main drill tap uses six cutting edges to cut clean CC threads in cast iron and ductile iron pipe under pressure. The Reed DT100 drill tap handles 1 in. service connections. PVC variants (DT75P and DT100P) use a three-flute design for C900 pipe.
Key Features of Reed DT75 & DT100 Water Main Drill Taps
Six Cutting Edges for Clean Threads
Each Reed DT75 drill tap has six cutting edges that produce clean CC threads, reducing the chance of leaks at the corporation stop connection.
Sharp Centering Point
A sharp centering point bites into the pipe wall on first contact, keeping the tap aligned for a clean start on pressurized mains.
AWWA Approved (DT75 and DT100)
Both the DT75 and DT100 carry AWWA approval as a drill tap for cast iron pipe and ductile iron, meeting the standard required by most municipal water specifications.
Three-Flute PVC Variants (DT75P and DT100P)
The DT75P and DT100P use a three-flute design that retains the coupon and cuttings inside the tap body, preventing debris from entering C900 PVC water mains during live tapping.
Broad Tapping Machine Compatibility
Both the DT75 and DT100 work as a drill tap for tapping machine models from Reed, Mueller, and Romac. Crews already running a TM1100, B-101, or Transmate can use these taps without adapters.
Two Service Connection Sizes
The DT75 handles 3/4 in. CC service connections, and the Reed DT100 drill tap handles 1 in., covering the two most common residential and commercial water service sizes.
