Poor design

The center post was way too long so much so to get the depth it would have gone through door. What were they thinking. I had to grind down the post and lose its cutting edges.

Works great!

Best drill bit I’ve ever bought. I was making so, me cap racks for my daughter who was giving them as Christmas presents. They included drilling 10, 1-1/2” holes in a 3 ft 2x4 times 6, after the first try with my cheap foreign forstner bit set, I gave up and went to Lowe’s and grabbed a new marbles bit. It took me longer to go to Lowe’s and back than it did to finish drilling the other 50 holes, I was amazed! I’ll never use any forstner bit but a Marples, fastest, smoothest holes I’ve ever dri...
