Needed to machine 96 holes for dowels. I needed them to be 8mm but couldn't buy a 8mm spiral upcut, downcut or end cutting bit. I had a 1/2" spiral upcut so I bought a cheap 8mm straight cut 2 fluted tungsten bit.
Test run done and the dowel was loose, loose, loose:~
Measured the cheap bit.

Not only was the router bit oversize, the cutters were off centre as the machined hole was bigger.
Ordered a "proper" 8mm bit and measured that.

Glad I test cut before machining the 96 holes:rolleyes:
