Drill AmericaDEWA/CCBR3/4 DEWCBR Series Qualtech High-Speed Steel Aircraft Counterbore, 1/4" Shank Diameter, 3/16" Pilot, 3-1/8" Length, 3/4" Size (Pack of 1)

GREAT QUALITY, would buy again

This counter bore worked great for what i needed.

Happy with delivery and it works well.

Very Sharp and very well made bit. I have purchased several of these and the others all had a radius on each of the flutes. This creates a very nice 90 degree cut.

Very good for pillar installing for rifle bedding

The tool was good quality and was delivered on time as promised.

On par with most Taiwan products level. Excellent for wood and plastics and that's what I bought it for. The 1 star is for their customer service. When I bought this I opened it and the tiny set screw fell out and it's so small who knows where it went in my shop. I contacted them to ask what was the exact size of the screw so I could replace it locally or I would buy a few from them. I contacted them through Amazon, their website, and by phone, and zero response from any, and it's been over a week as of today. The product is good, just know if you need any kind of help you will be without.

as expected
