I used larger diameter forstner bits (1.5” & 2”) when making a LOT of large mortices for my timber frame house. I bought good quality bits (Frued and Wolfcraft) as individuals and kept them sharp.

These were used with a 7 amp. Dewalt spade handle drill (w/ 1/2” chuck) that will literally break your wrist or throw you before it will stall. And despite beign very careful to tighten the chuck very tight…. the bits still managed to slip. This of course damages the bit shank and unless they are cleaned up in a good lathe, they will no longer align perfectly true in the chuck.

So on the big bits, that generate a lot of force, the hex shaft is of great help.

For small diameter bits held in a good drill press chuck, it probably won’t make much difference.

I have a gold tinted set (Titanium nitrate if I recall correctly) that I picked up from Grizzly or some other importer years ago. They came in a wooden box that looks very similar to the Grizzly set shown in your link. These are O.K., but the complexity of the geometry and machining is not nearly as good as the Freaud or Wolfcraft bits I purchased at individuals. You definatley want the saw teath machined in the outer rim.

Of the ones you linked, I would go with the Freaud set from Peachtree.

In the final analyses, $10 should not be a deal breaker.

And I agree, that in that 16 pc set, you will likely only use four bits. But which four? And will you have them when you need them. Or will you be forced to use a differnet style of bit, when the forstner is what you really need.

Good luck.
