Based on my experience, this bit was a letdown. While it was marketed as an industrial and scientific tool, it failed to perform up to par. The pros were that it was affordable and appeared durable. However, the cons were its lack of precision and the difficulty of achieving a clean cut. Overall, I wouldn't recommend this product for those in need of a reliable and accurate countersink bit.
Pros
Durable and long-lasting due to being made from carbide
Cons
May require additional tooling or accessories for proper use
jury oasis haven't gotten around to it yet, tried a few times with the smallest cutter out of the three, I shouldn't have set the correct speed The quality of the tool is very good for the price.
Pros
(additional bits sold separately) for 1/4"-3/4" x 1/2" shank TCMT32.51 (P/N 2224-1034)
Depending on the selected countersink diameter, knowing the speed and the feed rate z per minute determines the quality of the countersink. It would be nice if this company included some basic feeds and speeds for each countersink diameter as a starting point.
