Video: Benefits of Negative Rake Cutter Turning Tools
Basically the cutting tool slopes away from the cutting edge, which means safer, smoother and more continuous cuts in those very hard materials. Easy Wood Tools Negative Rake Replacement Cutters use that technology to make shaping man-made materials like resins and acrylics, but also very hard woods.
Rob Johnstone: Woodturning is as old as the hills. Something that's really come to the fore of late is the desire to turn resin-based plastic materials like this acrylic that I have mounted here. For good reason, because these blanks come in a variety of beautiful colors and hues and look great when they're turned into handles and pens. They can be challenging to turn as they are very hard and quite brittle.
That's where Easy Wood’s Negative Rake technology really comes to the rescue. Negative rake refers to the shape of the cutting angle of the carbide. Basically, the cutting tool slopes away from the cutting edge at an optimal angle. Designed to be much less aggressive than the standard cutter, Negative Rake Cutters result in safer, smoother and more continuous cuts in those very hard materials. For your benefit, Easy Wood Tool provides Negative Rake Cutters as an interchangeable option for all of their standard tools.
There are square cutters for roughing or truing up your blank, round cutters for inside and outside curves and a diamond-shaped for fine details. Easy Wood Tools is the innovator when it comes to carbide turning tools. Everything from the ultra-practical square toolbars, their innovative scroll chuck, to their elegant negative rake cutters. I've been hearing about Negative Rake Tools for a while now. I really wanted to learn more about them. I hope this video has been interesting to you and you might have learned a thing or two. I'm Rob Johnstone from Woodworker’s Journal. Keep on making plastic.
