Impact-ready accessories are no longer a nice option in the tool-box but more of a necessity. In the last decade, impact tools have proliferated but the response in related accessories has been lacking. And if you use an impact tool without an impact-ready accessory, you’ll soon discover just how much impact one of these tools delivers as you shatter a bit and/or driver. Use an accessory designed to stand up to your tools. DEWALT impact-ready bits take advantage of a uni-body design eliminating the chance of failure at drill bit shank and hex shank. Keep in mind that their design also takes advantage of a noticeably shorter bit overall so while the length should work for most applications, you should keep that in mind for some others. Dewalt drill bit set is made in USA or Denmark.
