Buying Guide

Match tap thread and pitch

Confirm NPT or metric designation and the correct pitch to ensure the tap fits existing pipe threads without rework

Choose HSS for durability

High-speed steel (HSS) taps and drill bits resist wear in maintenance use and handle common ferrous materials found in pipe work

Prefer tap-and-drill kits

Kits that include the correct size drill bit and tap streamline setup and reduce the chance of mismatched hole sizes

Check pilot/drill size compatibility

Ensure the drill bit diameter matches the tap's recommended pilot size to form proper threads and avoid taper issues

Consider common maintenance sizes

Select taps in frequent service sizes (NPT or common metric sizes like M18) to cover typical repair and replacement needs
