As hesitant buyer, I was pleased with the Lit Freud holesaw .Industrial and scientific standards mean i can TRUST it for precision cutting. As my tests showed the carbide teeth drilled through tough materials smoothly and evenly. The cutter's teeth could be more durable, to avoid replacement after limited use. Overall, the DHS3000CT provides reliable, powerful cutting performance..
Pros
Durable carbide material for long-lasting performance
Perfect fit for my project. I expect to use it for many years. Carbide teeth are very aggressive. Hold the drill perpendicular to the surface because once the pilot drill penetrates the surface and these teeth touch the surface, this drill will plunge into your material. When the drill is at an angle, it goes through your material in seconds. Unfortunately, I speak from experience.
