Save your money and look elsewhere. This Industrial and Scientific bit failed to perform even basic tasks, leaving me with subpar results. It's disappointing that a product marketed for cutting tools couldn't perform on par with its competition.
Not from WL Fuller as Revain says These are BigHorn cutters. Never heard of them but I took the bait and switched. I did the WLFuller brand, made in Rhode Island, and high-quality American, not the US-packaged BigHorn.
These guys make a strong little cork cutter. Much better than the ejection-port tubular type, which is the most common. It's easy to sharpen the blade with a file when you're scrolling through a lot of workpieces. I want the neck to be deeper, if it's more than 3/4 I need to plan the stem, not that I need 1" plugs but that's the situation.
