Typical Applications
- High-performance cutting of steel pipe, solid bar, and profile work where the material is harder or the line output is higher than normal M35 practice.
- Carbon steel, alloy steel, and stainless steel cutting on stationary and flying cut-off machines, especially where steel pipe saw blade life is under pressure.
- Automotive and precision tube applications using stronger steel grades, often around 850 MPa, more demanding stainless steel, or higher-performance cut-off machines.
- Shops that need HSS circular saw blades for metal cutting but want a premium grade before moving to carbide or cermet solutions.
Key Performance Advantages
- M42 Co8 is the high-performance HSS cold saw blade option for more difficult steel and stainless jobs.
- It is designed for stronger edge retention, higher wear resistance, and better high-temperature performance than M35 in demanding metal cutting.
- The special multilayer PVD coating and tight manufacturing tolerances support better cut stability, lower runout, and improved flatness control.
- This HSS saw blade is especially useful when cutting speed, section difficulty, or machine output pushes beyond the practical daily range of standard HSS grades.
Problems This Circular Saw Blade Helps Solve
- Premature wear and short resharpening intervals when M35 HSS cold saw blades are used on harder steel pipe, solid bar, or demanding stainless sections.
- Lost productivity on high-output cut-off lines where standard HSS grades cannot hold edge life long enough.
- Inconsistent cut quality in more difficult steel and stainless applications that generate higher cutting temperatures.
- Excessive downtime when tougher materials force repeated blade changes on stationary or flying cut-off machines.
Application Notes
- Choose M42 Co8 for harder steel pipe, solid bar, alloy steel, and stainless steel work, often around 850 MPa in demanding cold saw programs, where M35 is reaching its practical limit.
- This high performance HSS cold saw blade is best suited to demanding steel cutting programs rather than basic daily carbon steel work that M2 or M35 can handle economically.
- For the best results, match coating, tooth geometry, feed, coolant strategy, and machine rigidity to the material strength and section type.
- If the main workload moves far beyond normal HSS cold saw practice, especially in sustained ultra-high-strength production, evaluate carbide or cermet alternatives as well.
Grade Selection Guide
- Step down to HSS Saw Blades for Stainless Steel and Medium-Tensile Steel if stainless steel and medium-hard steel are the main workload but the process does not require the highest HSS grade.
- Step down further to HSS Saw Blades for Carbon Steel and Aluminum Tube for routine carbon steel, common alloy steel, and aluminum tube cutting where overall tooling economy matters more than maximum grade performance.
- Stay with this grade when harder steel pipe, solid bar, stronger steel grades, or high-output cut-off lines make M35 life no longer acceptable.
