Description of ๐ ๏ธ Enhance Your Drilling Reach with Drill America DWDA CX61 Extension!
High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of tool holding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Manufactured to national aerospace standard 907.
Good for deep drilling wood joints to insert a termite killer. Length enters pest areas through multiple stacked 2x4's detected with an IR camera. This drill easily makes the many holes needed to saturate termite nests. I roughed up the round shank of the drill to hold the drill in place while I worked. Hex shank is better for deeper or harder drilling.
I have had no luck finding the size bit I need at a parts or hardware store and they don't seem to make many extensions that fit round shaft bits who work in drills. It was just what I needed to get to the place I needed to reach and get the job done, the product was shipped and delivered quickly and was of excellent quality. I will buy from the seller again if the need for a somewhat hard to find source arises.
Received two identical drill bits packed separately in plastic tubes. Wanted to use them only to find out they were both bent and probably left the factory that way. The tubes are not bent, but the bits inside are bent. Not one, but two. And not just slightly curved, one of them looked like a spinning helicopter when I inserted it into my drill. Unused and returned. Not a good product at all
