SOMADA 3/8-Inch x 12-Inch Auger Drill Bit for Wood, Hex Shank 3/8-Inch One Piece, Ship Auger Long Drill Bit for Soft and Hard Wood, Plastic, Drywall and Composite Materials

I ordered 2 on separate orders. A 10" and an 8" length. My first one was working well as designed. It ruined on me after only the 8th hole drilling. All my fault. I accidently hit a Simpson Strong Tie 1 1/2" hanger nail on the other side of the double joist and 4x6 post. The screw tip got destroyed and got dull of course but completed about 2 more holes before I went to a spade bit to complete the job. Not the tool's fault for being destroyed. Drills through pressure treated lumber with ease and minimal need to wobble the bit. It seems to pull itself in as well like some of the name brand auger type wood drill bits. I like the 3/8" hex type shank. More torque allowed with a 20v Dewalt drill driver. Thought I was going to be able to use it with my 12v Dewalt impact driver in a pinch but the shank is not going to fit the 1/4" impact driver's bit holder. Works well and my 2nd one is doing well with none of my mistakes from the first one.

These work well. I did a ton of drilling with only one bit. I still have a second one for a future date. Good Product. Use a powerful drill. One with a power cord. Using these kill battery powered drill batteries quickly.

I needed a 9/16" diameter 15" long drill bit. Could not find this diameter in any big box stores or local hardware stores. they were available on line with delivery in November. Amazon shipped this one quickly. Excellent product and the best price I could find.

These are well-built and may work, I just need to find a drill with a large enough opening to take the tool. Thus far, I haven't found a large enough drill to accommodate this tool.

Perfect drill for my tree. I drill holes in my tree trunks too kill them. It's super thick and long. It's very sharp. This is very strong and didn't break. Great price.

Good bit for the price

Good

Giving this 4 stars because it helped me complete a task very fast. The bit is fairly sharp out of the box. Only rating 4 stars because I am not sure yet about longevity of the bit.
