Screw Countersink Bit set
Nice countersink set from Makita. They adjust for both drill bit length and countersink depth. Clean, accurate holes every time. Including the metric Allen wrench was a nice touch. I recommend these.

I am working on a project in which this tool will make things easier, and the countersink bit will be a great addition to my workshop. Of course, I am pleased with Makita products, and own a number of their power tools, so I know their workmanship is good.

Need a new set of countersink bits. If they are as good as some of the reviews, I will be happy. I'll see how they are when I get them and write a review.

I have a big restoration project
David Howton A on Mar 30, 2019
because ordering and check out was easy, went to a few of my other supplers and too much information was wanted, even when I bought from them many times, they don't need to know that stuff just to sell me an item,too time consuming.
