DEWALT Drill Bit, Ship Auger, 1 Inch x 17 Inch (DW1687)

This drill bit absolutely delivers! I needed to drill holes in old pine stumps to set them ablaze, and this tool is really helping me do that well. Clean cut. Doesn’t dig in too fast and get the bit stuck. Still looks very straight and sharp. This is a quality bit and is worth the money that I paid.

This bit is perfect if you have a large stump and are looking to use something like Spectracide Stump Remover or a similar product. For stump removers to work it is very important to follow the instructions and this is the mistake most people make when they use those products and find it doesn't work. You need to get several holes in to the stump that are an inch wide and preferably about 10 to 12 inches deep, and then another set of holes at an angle from the side to connect to the vertical holes. It is important the holes be about an inch wide and 10 to 12 inches deep for the stump remover to really work at its best and this is definitely the drill bit for that job. I took down an absolutely massive tree with a stump that was at its narrowest 5' wide and up to 9' wide at its widest point. Due to its location and size a stump grinder or burning it out simply isn't an option so a stump remover compound was really my only option, even if it will probably take quite some time. Luckily this bit was more than up to the task of at least getting the holes in the trunk to start the process and I was impressed with how quickly and easily this bit was able to handle the job.

Excellent for drilling holes in an old tree stump and applying salt to kill it. I had to find a corded drill with a second handle on it to perform the work safely. This could be a wrist-breaker with the wrong equipment. But, as far as the bit is concerned, Dewalt is a champ. Note that the threaded point will cause the drill bit to be pulled into the work. This means that the drill rotation must always be reversed for a brief time before being able to remove the bit from the hole. Reverse briefly, pulling up slightly from the bottom, then change to the regular direction rotation as you pull completely out of the hole so that the rotating bit helps clean the hole of the cuttings.

Like many others, I have bought the 1" bit to fight a freshly cut stump. I found the bit to be very sturdy and mostly invincible. I have used a Harbor Freight low-speed drill to drive it, while squatting on top of the drill and using the quads part of my leg to prop the horizontal handle whenever the bit got stuck and I needed an extra torque. A few times, I was able to use a socket on a breaker slide bar to drive the bit back to the surface when the drill could no longer move it back. The bit stayed mostly sharp through drilling 40 holes at full length all the way into a clay/mud under the stump. At that point it was not feeding nearly as well, but it was easy enough to re-sharpen using a basic small flat file. Towards the very end of the project, it just stopped feeding altogether. When I pulled it back, the top screw tip used for feeding the bit broke off. I assume this happened because the bit got dull again and I was drilling into the most dens and wet part of the stump, while not pressing on the bit hard enough. Basically, the screw kept going while the bit stayed still, effectively twisting the tip off. Without the tip, the bit is of no use - it would not feed at all. I've tried welding a new screw tip, but that one broke after two more holes. At that point I was around 85-90 holes. Overall, I think this is a quality tool. But seeing other people reporting the same issue with the broken tip, you might want to be mindful of the keeping the bit sharp and maintaining a good pressure to make sure you can maintain a proper feed rate. And maybe go a bit slower.

This bit cut through railroad ties like butter. Stayed sharp the entire time. Worth every penny.

PROs: This thing is a monster! Chews through wood and even nails (although I did not intend to go through nails). I was building a new home and did some DIY running of data cables, security cables, and coax cables though 1 1/4" Carlon flexible PVC tubing (blue "smurf tubing"). I probably did 50+ holes, with most some going through double- and triple-stacked 2x4 beams. Although the bit has dulled somewhat, it is still well capable of drilling more holes. CONs: YOU NEED THE CORRECT DRILL -- it needs to be powerful enough. I have a 26v battery-powered Dewalt and a 6-amp wired Craftman that couldn't do the job (not enough power). Solution? I bought the largest amp drill I could find ... a 10-amp wired Dewalt. Unfortunately, because of the large amp draw, I also had to buy 150' of 12AWG wire as per the drill's instructions (a smaller sized wire would have resulted in reduced power and danger of overheating). Note: You may be able to go with smaller sized wire [larger number AWG] depending on the distance you're running it. During home construction there is only one electrical outlet and for me it was 100+ feet away. Notwithstanding, I would still get 12AWG wire even over shorter distances just to be safe. Notwithstanding -- BEWARE -- if you don't have enough power to drive this bit, it will not work for you.

When Hurricane Michael destroyed my dock and seawall, I decided to change the design and use 1/2 inch stainless steel threaded rods with stainless steel nuts and washers to secure the dock structure to the new pilings. The problem was that I needed to bore a 5/8 inch hole through two 2x10 crossmembers and 8 inch pilings. And, I had 60 of these I needed to drill through. I tried a spade (flat) bit that didn't even get started into the piling. So, I purchased this Dewalt Auger Bit and started using it on the piles that I hadn't installed yet. I was using my 1/2 inch corded drill and it bored a clean hole without a problem. However, I had already jetted most of the piles already and I couldn't use my corded drill on those. I tried using two different 1/2 inch battery powered drills and they couldn't handle the job. These drills would bind and stop before I could even through the 2/10. So, I purchased a Milwaukee M18 FUEL 1/2 inch portable drill. This drill and the Auger Bit handled the job easily. I also ran into nails and hardened screws in some of the old pilings and the bit was able to handle those. I purchased two of these auger bits thinking that one would wear out before I finished all the drilling; however, I have not opened the second bit yet and I have completed approximately 90 holes so far (for both the crossmembers and for the stringers). I would highly recommend this bit.

This drill it is a beast, eat wood like crazy. highly recommended

Muy buen producto

très bonne qualité et très efficace

Suggested by a friend to drill holes in which to place food spikes for trees. Does a FANTASTIC job, efficient and speedy. You will move along like greased lighting. My 20 volt DeWalt drill pairs magnificently with this bit. Highly recommended, especially if you have lots of (hungry) trees.

Used this to dig holes into the ground for setting up garden sticks, and it did an amazing job. The ball groove shank is too big for my drill, so had to pay extra to get an adapter.

I got this to make a few holes in my building too plate, it went through 3 2x6 like it was butter!!! Nice price too.
