I recently needed a custom router bit to match a 15 year old routed MDF door profile. I found by chance an excellent manufacturer I wanted to pass on to any of you in need. They were very pleasant to work with and have a 7 to 10 day turn around. Mine took slightly longer since I ordered it right before Christmas. Although expensive for only 1 door, my client was more than happy to pay for the bit. Great folks and very happy with the service and finished product.
