Questions & Answers

With this cut a 45° along the entire edge of 3/4 material
ByJun 20, 2024
1 Answer | 
Answer This Question

The product information states that this bit has a carbide height of 5/8". Therefore, it will not cut a 45° chamfer along the entire edge of ¾" material. It will only chamfer to a depth of 5/8".

    Answer This Question

    Hi John! Diablo Chamfer bits are not recommended for routing fiber cement products like Hardie Board. You will get best results if you use PCD-tipped bits (polycrystalline diamond) for routing this material. I am not sure these are available in the market in a chamfer profile. If not, you may want to consider ripping the chamfer using Diablo’s D0704DH PCD-tipped Hardieblade.

          Is this a 45-degree chamfer?
          ByDec 1, 2020

          Answer This Question

          No. It is slightly greater than 45 degrees. Enough to notice when joined with another chamfered edge for it to be out of square.

              Hi Ryan, yes it will work well for that. Just adjust the depth to the width of face you want.

              By|Oct 26, 2020

              Hello Ryan, thanks for reaching out! The DR40106 Chamfer bit has a cutting height of 5/8”, so it will rout a chamfer up to that dimension on the edge of a 2x4.

                If you are working with 3/4" plywood, would this bit allow you to cut a miter across the 3/4" board thickness (resulting in a miter face with a 1 and 1/16" hypotenuse? If not, what is the thickest plywood for which this bit will cut a 45-degree miter?

                Hello Marco! The DR40106 Chamfer bit has a cutting height of 5/8”, so it will not rout a miter the full thickness of ¾” plywood. With a careful setup it will rout the full thickness of 5/8” plywood.

                  Freud router bit
                  Four stars due to information incorrect and lacking. Project required a bullnose profile and a good time to use up a gift card. Since there was no listing of the radius profile I did some research using the Diablo model number and it turns out to be similar to the notch up to the Freud model number of 82-106 which is listing a 1/4" radius. So it was a good bet all dimensions were the same. Did receive a Freud router bit. Use both Freud and Diablo products, confident performance will be fine.

                    Great product, I used it for making a chamfer edge to 40+ coasters, and worked great. Used it in a craftsman router set in a router table. Price was also nice.

                    Might not fit smaller routers
                    I have a small Makita compact router i planned to use with this, but it will not fit because the diameter at the top of the cutting surface is too large for the opening in the router bottom plate. It worked great in my large router that has a larger opening.

                    The bit was sharp. It was too big for my router an I was unable to adjust the depth.
