Large Diameter Steel Pipe Cutters

Schallert Enterprises manufactures cutters up to 72 inches in diameter. Their Carbide Tipped and Diamond Segment cutters both reach 72 inches, while the HSS Tipped cutter covers up to 48 inches. All are custom-built to adapt to your specific tapping machine, making them suitable for the most demanding large diameter pipeline projects.

For large diameter steel pipe, carbide tipped or HSS tipped hole saw cutters mounted on a hot tapping machine are the industry standard. Carbide tipped cutters are the most popular choice for most steel pipeline materials, offering versatility up to 72 inches. HSS tipped cutters are specifically suited for tapping into steel lines up to 48 inches.

Schallert Enterprises offers three main cutter types: Carbide Tipped (up to 72 inches, suitable for most pipeline materials), HSS Tipped (up to 48 inches, ideal for steel lines), and Diamond Segment (up to 72 inches, designed for concrete lined pipes). All feature deep tooth profiles and can be adapted to any tapping machine.

Yes. All Schallert large diameter cutters are engineered specifically for hot tapping — cutting into active, pressurized pipelines without interrupting flow or service. This makes them essential for water main connections, pipeline modifications, and infrastructure maintenance where shutdowns are not feasible or cost-effective.

Schallert Enterprises custom manufactures each cutter to adapt to virtually any tapping machine in the world. When placing an order, provide your tapping machine model and tap size, and the team will engineer the cutter to ensure precise compatibility. Technical support and consultation are available to assist with specification.

Schallert's cutter range covers most common pipeline materials. Carbide tipped cutters work on most pipeline materials including steel, ductile iron, and PVC. HSS tipped cutters are optimized for steel lines. Diamond segment cutters are specifically designed for concrete lined pipes. Selecting the correct cutter type for your pipe material is critical for optimal cutting performance.
