If the counterbored portion is shallow (1/8-inches or less), the operation is usually known as spot-facing; for example, a flat seat for a bolt head or nut. If, on the other hand, the hole is enlarged to a considerable depth, it is designated as counterboring. This counterbore is made of two-piece construction, having an integral shank and counterbore-cutter, and a pilot that is interchangeable, which provides flexibility in the use of the tool. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Round shanks allow use with a wide variety of toolholding systems.

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.

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.
