Material Choice for Bandsaw Blades: More Information
This page takes a closer look at what bandsaw blades are made from and why it matters. Each blade material offers different strengths, and the right one depends on the material being cut, the finish you need, the cutting speed of your machine and how long you need the blade to last. If you just want a fast answer, our guide to choosing a bandsaw blade material sums it up; read on for the detail behind it.
How each blade material is made
1. Carbon steel blades
A carbon blade is made from a single strip of carbon steel, with the teeth hardened so they hold an edge while the back stays tough enough to flex around the wheels. They are the most basic and cost-effective option and work well on wood, plastics and soft non-ferrous metals. They are less durable than other materials and are better suited to moderate cutting speeds, but they are economical to replace and come in narrow widths for tight curves. Carbon blades are made in more than one style, which our page on the different types of carbon bandsaw blades explains. A popular style is covered on our flexback carbon bandsaw blades page.
2. High speed steel (HSS) blades
Solid HSS blades are made from a hardened steel alloy containing significant amounts of tungsten and molybdenum. This gives them greater heat resistance than carbon steel, so they can run at higher cutting speeds. Because a solid HSS band is less flexible, most modern blades put the high speed steel only where it is needed, at the tooth tips, which is how a bimetal blade is built.
3. Bimetal blades
A bimetal blade joins two metals: a strip of high speed steel forms the tooth edge, and this is welded to a flexible, fatigue-resistant spring steel back. The hard edge resists heat and wear, while the back can flex around the wheels thousands of times without cracking. The result is a long-lasting blade that handles steel, stainless steel and other metals well, copes with higher cutting speeds and can also be used on wood and plastics.
4. Carbide-tipped blades
Carbide-tipped blades have individual carbide teeth brazed onto a high-strength steel body. Carbide is extremely hard and wear-resistant, so these blades stay sharp for a long time in abrasive and hard materials such as dense hardwoods, hard metals, composites and exotic materials. They are a specialist product for demanding production work.
5. Diamond-grit blades
Diamond-grit blades have diamond particles bonded to the cutting edge instead of conventional teeth. They grind rather than cut, which suits hard, brittle materials like ceramics, glass and stone, where a toothed blade would chip the work.
Side-by-side comparison
- Carbon: lowest cost; best on wood, plastics and soft non-ferrous metals; suits moderate speeds; available in narrow widths for curves.
- Bimetal: longer life; best on steels and regular metal cutting; tolerates more heat and higher speeds; flexible back resists cracking.
- Carbide-tipped: specialist; best on very hard or abrasive materials; highest wear resistance.
- Diamond-grit: specialist; for ceramics, glass and stone only.
Getting the most from your chosen material
- Match the speed to the material. Carbon blades in particular do not like excessive heat, so run them at a sensible speed for the job. Our page on bandsaw blade speed rates gives guidance.
- Use coolant on metal. On steel, coolant or lubricant keeps the tooth edge cool and helps chips clear. See coolants and lubricants.
- Break the blade in. A light feed for the first few cuts helps any new blade last longer.
- Pick the pitch to suit the section. Whatever the material, keep at least three teeth in the cut.
Frequently asked questions
What is the difference between a carbon and a bimetal bandsaw blade?
A carbon blade is made from one piece of carbon steel, while a bimetal blade has a high speed steel tooth edge welded to a flexible spring steel back. Carbon is the economical choice for wood and general work; bimetal lasts much longer when cutting metal.
Why do bimetal blades last longer in metal?
High speed steel keeps its hardness at the higher temperatures produced when cutting steel, so the teeth stay sharp for longer. The separate spring steel back also resists the fatigue cracking that comes from flexing around the wheels.
Are carbide or diamond blades worth it for a home workshop?
For most home and general trade work, no. They are aimed at very hard, abrasive or brittle materials. Carbon and bimetal blades cover the vast majority of wood, plastic and metal cutting.
Additional Considerations
Various blade manufacturers offer unique variations of these materials, incorporating proprietary alloys or coatings to enhance performance. Blades also come in a range of widths, tooth pitches and configurations, so you can tailor the blade to the application. At SawMaster Ltd., we focus on stocking carbon bandsaw blades and bimetal bandsaw blades due to their widespread use and popularity in the industry.
Conclusion
In summary, the right bandsaw blade material depends on what you cut, the cutting speed and how long you need the blade to last. Carbon steel covers general cutting needs, bimetal brings much greater durability for metal, carbide-tipped blades suit hard and abrasive materials, and diamond-grit blades are for ceramics, glass and stone. Choosing the right material ensures efficient and effective cutting performance.
