Topic tags/keywords: 1014 tpi

What does this mean in a blade description? It has to do with the teeth per inch but past that I don’t know.

10/14tpi VR

I believe it breaks down like this:

10/14 tpi = variable tooth size and spacing, ranging from 10 – 14 teeth per inch
VR = variable raker, which is some sort of an optimized a tooth set pattern

Strange, not sure what the reason for that would be especially for doing resaw.

even a wood blade under the right circumstances like the cross grain pattern matching the tooth spacing can set up a harmonic that will leave an extremely rough finish or throw off tracking.

less vibration from blade harmonics. less vibration=fewer and shallower chatter lines in your cut.

The only place I’ve seen 10/14 TPI blades is on metal cutting blades. I believe the designation should be VP, not VR.
