Norseman Drill & Tool HSS Taper Pipe Taps

Norseman Drill & Tool HSS Taper Pipe Taps

Reliable NPT Threading for Pipe Fittings and Couplings

Norseman Drill & Tool HSS Taper Pipe Taps are engineered to produce accurate, leak-resistant NPT threads for pipe fittings, couplings, and ports across a wide range of materials. Manufactured from high-quality high-speed steel (HSS), these taps deliver the toughness, heat resistance, and cutting stability required for consistent results in both shop and field applications.

Regular Thread NPT Taper Pipe Taps

Proven Performance for Standard Pipe Threads

Norseman regular thread NPT taper pipe taps are designed to cut the standard 1 in 16 taper required for proper pipe thread engagement and sealing. The precision ground cutting edges ensure clean, accurate threads that meet NPT specifications, making them ideal for plumbing, hydraulic systems, pneumatic lines, and general industrial piping. These taps perform reliably in materials such as mild steel, cast iron, brass, bronze, aluminum, and many plastics.

Interrupted Thread Taper Pipe Taps

Reduced Friction and Improved Chip Control

For more challenging materials, Norseman offers interrupted thread taper pipe taps. This advanced design reduces contact between the tap and the workpiece, significantly lowering friction and cutting torque. The interrupted thread geometry increases chip capacity and improves coolant flow to the cutting edges, helping the tap run cooler and cut more efficiently.

Ideal for Long, Stringy Chip Materials

Smooth Cutting in Ductile Metals

Interrupted thread taper pipe taps are especially recommended for soft, ductile materials that produce long, stringy chips, such as aluminum, copper, and certain plastics. Enhanced chip evacuation reduces the risk of chip packing, improves thread quality, and helps extend tool life in demanding applications.
