I’ve been doing sign carves with the 60-degree V-bit from Inventables. Been using this bit for awhile and many signs with no problems.
Today I switched bits to a Whiteside 60-degree V-bit, 7/16 point length, 1/4” shank, 1/2” cutting diameter, 2” overall length. Seemingly identical to the Inventables bit.
However, instead of a usual flush surface in the carved areas, it’s has lengthy grooves. I measured both bits with a caliper and they are identical. But have never had this problem before.
The sign has three depths/layers: top surface of wood (uncarved, with letters), larger letters (seen with letter W in photo), and floor or lowest carve, completely flat.
Any ideas what is going on???
