As a HESITANT buyer I was skeptical of this bit`s capabilities. But as a result of using it, I found that it effortlessly cuts precise dados and grooves in hardwood .The build quality is top-notch and has a long lifespan. The only downside is that it's on the pricier side, but it's worth the investment for serious woodworkers. Overall, i highly recommend this industrial and scientific cutting tool for any woodworking project..
