Metal Cutting / Friction Sawing

Friction Saw Blades for Steel Tube, Section & Billet

Friction circular saw blades cut steel by generating localised frictional heat at the tooth-workpiece interface rather than by shear alone. This mechanism makes them suitable for high-speed cut-off on rolling mill and tube mill production lines where conventional cold saw blade cycle times cannot match line speed, or where workpiece temperatures are too high for carbide tooling.

This category covers two distinct friction sawing environments. Hot friction circular saw blades are designed for workpiece temperatures above 750 °C on hot rolling mill and tube mill lines—the blade body uses a special high-temperature alloy steel to survive the thermal and mechanical demands of high-speed hot cutting. Cold friction circular saw blades are designed for ERW tube mills and cold-forming lines where workpiece temperatures remain below 250 °C—spring steel or low alloy tool steel through-hardened bodies provide the toughness and wear resistance needed at high peripheral speeds.

What This Category Covers

Materials: Carbon steel, alloy steel, and high alloy steel tube, section, and billet.
Applications: Hot friction cut-off on rolling mill and tube mill lines (above 750 °C); cold friction cut-to-length on ERW tube mills and cold-forming lines (below 250 °C).
Machines: Hot rolling mill cut-off saws, tube mill friction saws, ERW tube mill cut-off saws, and cold-forming line cut-off machines.
Key Distinction: Hot friction for workpiece temperatures above 750 °C; cold friction for temperatures below 250 °C. Selection is determined by line type and workpiece temperature, not by material grade alone.

Hot Friction

Hot Friction Circular Saw Blades for Rolling Mill & Tube Mill Lines

For cut-off of carbon steel, alloy steel, and high alloy steel tube, section, and billet at workpiece temperatures above 750 °C on hot rolling mill and tube mill production lines. The blade body is manufactured from a special alloy tool steel engineered for stable performance at the elevated temperatures generated by high-speed friction cutting of hot steel.

Hot Friction / Rolling Mill & Tube Mill

Hot Friction Circular Saw Blades

Hot friction circular saw blades for cutting carbon steel, alloy steel, and high alloy steel tube, section, and billet on hot rolling mill and tube mill production lines. Designed for workpiece temperatures above 750 °C, with a special alloy tool steel body for reliable performance at high peripheral speeds. The blade cuts by frictional heat generation rather than shear—making it suited to high-temperature primary steel processing where cold sawing is impractical.

Cold Friction

Cold Friction Circular Saw Blades for ERW Tube Mills & Cold-Forming Lines

For cut-to-length of steel tube and cold-formed section on ERW tube mill and cold-forming production lines where workpiece temperatures remain below 250 °C. Manufactured from spring steel or low alloy tool steel plate, through-hardened for high peripheral-speed reliability. An economical high-throughput cut-off solution for continuous tube mill and roll-forming operations.

Cold Friction / ERW Tube Mill & Cold-Forming

Cold Friction Circular Saw Blades

Cold friction circular saw blades for cut-to-length of steel tube and cold-formed section on ERW tube mill and cold-forming production lines. Manufactured from spring steel or low alloy tool steel plate, through-hardened, for reliable performance at high peripheral speeds with workpiece temperatures below 250 °C. An economical cut-off solution for continuous tube mill and roll-forming lines where burr-free quality is secondary to throughput rate and blade cost.
