As a professional contractor or tool distributor, selecting the right oscillating multi-tool blade is crucial for efficiency and cutting performance. Different blade types excel at cutting specific materials. Johnson Tools offers a comprehensive range of oscillating saw blades designed for universal compatibility (fitting Bosch, Dewalt, Dremel, Makita, Fein, and other major brands) and built to meet the demands of B2B customers.
This guide compares three main types of oscillating blades – High Carbon Steel (HCS), Bi-Metal, and Carbide/Diamond Grit – and explains their best uses and advantages for professional applications.
High Carbon Steel (HCS) Blades – For Wood & Plastics
HCS blades are made of high-carbon steel and are the go-to choice for cutting wood, plastic, and drywall. They typically have sharp teeth (often with specialized designs like Japanese double-row teeth) that provide clean, precise cuts in soft materials. Contractors favor HCS blades with Japanese tooth geometry for finish carpentry and interior renovations because they cut smoothly with minimal splintering, reducing the need for sanding.
However, HCS blades are not suited for cutting metal. If an HCS blade hits a nail or screw, it will dull quickly. They trade durability for affordability and precision – making them ideal for quick jobs on wood or plastic, but not for heavy-duty demolition. Johnson Tools’ HCS oscillating blades are engineered from heat-treated steel for longer life, and their ultra-sharp teeth ensure splinter-free finishes on wood cuts. For example, a Johnson Tools Japanese-tooth HCS blade zips through softwood or plywood while leaving a clean cut line – perfect for trimming door jambs or cutting laminate flooring to size.
Key Applications:
Cutting soft wood, plywood, drywall, and plastics; jobs requiring fine, clean cuts (e.g. finish work, precision trimming). Not recommended for metal or nails (to avoid blade damage).
Bi-Metal Blades – The All-Purpose Workhorse
Bi-metal (BIM) oscillating blades feature a high-speed steel tooth edge welded to a flexible steel body, combining hardness with flexibility. This hybrid construction gives excellent durability and allows them to cut through both wood and metal without breaking.
In practice, a quality bi-metal blade can slice through wood with embedded nails, cut PVC or copper pipes, and tackle sheet metal in remodeling jobs without needing a blade change. This makes bi-metal blades the professional’s choice for versatile, mixed-material tasks.
Johnson Tools’ Professional Universal Oscillating Blades are predominantly bi-metal blades designed for multi-purpose cutting. They use hardened high-speed steel (M42) teeth for cutting metals and a tough alloy back for flexibility.
Many are titanium-coated bi-metal blades, where a gold titanium nitride coating protects the teeth from heat and wear. This titanium coating lets the blade stay sharp 2–3 times longer than standard bi-metal blades. In other words, Johnson Tools’ titanium-coated bi-metal blades “cut through the competition” by offering extended longevity and performance.
They are ideal for renovation and demolition tasks where you might encounter wood, drywall, plastics, and the occasional nail or screw in one job.
Key Applications:
General-purpose cutting – e.g., cutting wood with nails, trimming plastic pipes or PVC, slicing drywall or sheet metal. Bi-metal blades are a must-have for contractors doing demolition or retrofitting, as they handle surprises like hidden nails without a hitch. The titanium-coated bi-metal blades from Johnson Tools are especially suited for long-duration use on job sites, maintaining sharpness and cutting speed even under heavy use.
Carbide & Diamond Grit Blades – For Hard Materials and Abrasives
When standard metal blades aren’t tough enough, carbide and diamond blades step in. These blades are designed for the hardest, most abrasive materials that contractors encounter. Carbide-tooth blades have carbide metal welded onto their teeth, allowing them to cut through hardened steel, cast iron, and dense composites that would destroy a regular blade.
For example, a carbide-tooth oscillating blade can cut stubborn nails, bolts, or even a cast iron pipe without immediate dulling. They also excel at slicing through tough materials like fiber cement board or plaster.
Carbide-grit blades (often half-moon shaped) and diamond-grit blades take a different approach: they don’t have teeth at all but instead have an abrasive edge. Diamond grit oscillating blades are coated with industrial-grade diamond particles, making them capable of grinding through extremely hard materials like ceramic tile, masonry, stone, and grout.
Key Applications:
Hard & abrasive materials – cutting ceramic tiles, concrete, brick, removing mortar or grout, and slicing through hardened metals. Use carbide-tooth blades for metal pipes, nails, or cement board, and diamond-grit blades for masonry, tile and grout removal. These blades are essential for contractors in construction, tiling, or heavy renovation work where standard blades won’t last.

Conclusion
In summary, oscillating tool blades come in specialized types suited for different tasks. HCS blades deliver quick, clean cuts in wood and plastic, bi-metal blades handle mixed materials (wood, metal, drywall) with durability, and carbide/diamond blades conquer the hardest substances like tile and steel with unmatched longevity. By understanding these differences, professional contractors can choose the optimal blade for each job, leading to smoother cuts, longer blade life, and cost savings through fewer replacements.
Johnson Tools provides all three blade types with an emphasis on quality and B2B support. With their blades in your multi-tool, you’re equipped for precision work and heavy-duty jobs alike – ensuring you can cut, renovate, and build with confidence. Each blade is an investment in efficiency and reliability on the job site, helping professionals like you deliver excellent results every time.
