Circular Saw Blade Dedra H18540 for Wood, 40 Teeth, Ø185×20 mm

Dedra H18540 is a circular saw blade for wood with 40 teeth and dimensions Ø185×20 mm. Intended for use in circular saws and table saws with a 20 mm bore, this blade combines a compact diameter with a medium tooth count to handle a range of general woodcutting tasks. The tooth geometry and plate thickness are matched to common workshop and construction applications, making it suitable for crosscuts and rip cuts in both softwoods and hardwoods.

Advantages

The 40-tooth configuration balances cutting speed and finish quality, delivering reasonable feed rates while producing a cleaner cut than coarse blades. A 185 mm diameter offers compatibility with many compact and benchtop saws, while the 20 mm bore ensures a secure fit on machines designed for that arbor size. The blade is suitable for routine woodworking tasks and provides predictable performance when used with appropriate saws and proper technique.

Suitable for

• Crosscutting and ripping of softwood and hardwood
• General workshop and hobby woodworking
• Use in circular hand saws and table saws with 20 mm arbor
• Sheet goods and dimensional lumber cutting

Key specifications

• Diameter: 185 mm
• Arbor bore: 20 mm
• Number of teeth: 40
• Intended material: wood (softwood and hardwood)
• Typical applications: crosscuts and rip cuts

How to use

Install the Dedra H18540 blade on a compatible circular saw or table saw with a 20 mm arbor, ensuring the saw is unplugged or the battery is removed before fitting. Verify the blade rotation direction matches the saw’s arrow marking and tighten the arbor flange to the manufacturer’s recommended torque. Set saw speed and feed rate appropriate to the wood species and thickness; for harder woods use slower feed to avoid burning, for softwoods a faster feed is acceptable. Use proper supports, guide fences or miter guides for straight cuts and apply appropriate personal protective equipment such as eye and hearing protection and a dust mask.

Usage recommendations

Maintain blade sharpness by avoiding cutting materials with embedded nails or screws, and periodically inspect for damage or dulling. Clean resin build-up after prolonged use and replace the blade if teeth become chipped or the blade shows signs of warping. Follow machine manufacturer guidelines for maximum RPM and safe operation.
