HD Metal Band Saw Blade Various Size And Pitch Specifications For Different Material Processing Jobs

Product Introduction

The JSSCD HD Bi-Metal Band Saw Blade is a high-performance metal cutting blade developed for hard and difficult-to-cut materials that require higher tooth hardness, wear resistance and impact resistance.

The HD series uses Japanese-imported M51 special high-speed steel as the tooth material and B318 alloy steel as the backing material. After a specialized heat treatment process, the tooth hardness can reach HRC 69–70, providing high tooth-tip hardness, excellent wear resistance and the ability to withstand stronger impact forces during cutting.

Combined with the ductile backing material, the HD blade provides a balance of tooth hardness and blade toughness. It is particularly suitable for materials that are difficult to cut with conventional M42 bi-metal blades, including special alloy steel, high-temperature alloy steel, tool steel and mold steel.

Key Features

M51 Special High-Speed Steel Teeth

The HD series uses Japanese-imported M51 special high-speed steel for the tooth tips, providing higher hardness and wear resistance than conventional M42 tooth material.

HRC 69–70 Tooth Hardness

After specialized heat treatment, the tooth hardness can reach HRC 69–70, helping the blade withstand demanding cutting conditions.

Excellent Wear Resistance

The high-hardness M51 tooth material is designed for applications where conventional blades may experience faster tooth wear.

High Impact Resistance

The HD tooth structure is designed to withstand stronger impact forces during cutting hard and difficult-to-cut materials.

B318 Alloy Steel Backing

The blade body uses B318 alloy steel as the backing material, providing the toughness required to support the high-hardness cutting edge.

Hardness + Toughness Balance

The combination of a high-hardness M51 tooth tip and a more ductile backing material provides a balance between cutting-edge durability and blade toughness.

Designed for Difficult-to-Cut Materials

HD is suitable for materials that may be difficult for M42 bi-metal blades to handle, including special alloy steel, high-temperature alloy steel, tool steel and mold steel.

Multiple Tooth Pitch Options

The HD series is available in multiple blade sizes and tooth pitches to accommodate different workpiece dimensions and cutting requirements.
