These Trend’s Professional WAVEFORM circular saw blades are designed to be able to perform industrial and professional applications. They feature Micro-granular carbide tips that offer long-lasting performance, even when used with abrasive materials. These sawblades are laser cut from chrome alloyed steel plate that’s been specially hardened and the body of these blades is tempered and roller tensioned so they will maintain trueness. This technology means they can be re-sharpened the maximum number of times for outstanding tool life. These saw blades have standard sizes of bore (16mm, 20mm, and 30mm) but the bore can be reamed if necessary to suit other requirements.
