Best self feed bit I've ever used. I use it to drill through 2x16 joists and it is amazingly fast. As other reviewers have stated do not use this with a drill that doesn't have a clutch. I use it with the Dewalt version of the 'hole-hawg' which is DW124K.
That monster has enough mass and grip to allow me to hold it steady while drilling. The only time it has hurt me was drilling through a small piece of 2x4 which slipped and hit my leg (to prevent this first screw the smaller boards to larger pieces that will hold the small piece still while you drill).
Never had a problem on joists which is what this is made for. I'm fairly certain I've even drilled though screws and nails and mine still keeps going.
Super aggresive bit. Do a lot of wood working and bought this specifically for a project at work with exterior plywood. Bites into wood and tears through it. Biggest issue was having a drill strong enough to power through the cut.
Would have no issue boring through stud grade lumber all day other than holding on.VERY aggresive bit.
I am very happy with this product and recommend it to anyone boring under sidewalks. I use it to run drip irrigation tubing and small PVC. I would not be as successful with it if I weren't using it with my Klein Flex Bit Placement Tool.
Used together, you can avoid digging a long trench out beside your sidewalk and keep your bit headed just where you want it, which is just under the concrete, not angled down deeper and deeper. I would love to see it offered in a 1 inch or 1 1/4 inch as well.
The Snappy Self-Centering 5/64" Drill Bit Guidemakes it extremely easy to start a hole in ametal pipe exactly where you want it - a jobwhich normally is difficult, and often resultsin a hole where you don't want it. This productis well designed and a pleasure to use.
This bit chews right through joists. I used it to make about 100 holes through some dense old 2" thick pine joists and it ate through them like a champ.No complaints.
I've been using these large self feed bits for years and I must say that these are pretty good. They feel a little softer than there predecessors. But being able to replace the parts of this bit that come into contact with the wood is awesome.
You can replace the cutting blades , the center auger/feed screw and the allen bolts. Helpful tip* Buy this 2 1/8 " bit if you don't specifically need the 2 1/4" bit. The replacement blades are available in a ten pack for the 2 1/8" but only singles ( so far ) for the 2 1/4" bits.
Much cheaperr if you use them a lot ( like drilling holes for smurf tube in new house during pre-wires.
The best large hole wood auger bit I have ever owned. Chewed through heavy treated lumber like butter. Recommend use only with HD low rpm high torque 1/2 or 5/8 drill motor with Aux handleto better control the feed rate of this aggressive auger bit.
This bit will quickly overheat and overload all but the heaviest duty cordless drills. In summary: if you need to bore accurate round 3 holes rapidly with absolutely clean surface this Milwaukee auger bit will exceed your expectations. Note: hang on tight because it feeds into material quickly, and make sure you tighten the pilot center set screw very tightly with supplied wrench so it does not detach in your bored hole when backing bit out of a blind hole.
Primary use of this set is not construction but rather an alternative to forstner drill bits it sizes from 1/2 " up to 1 3/8". I did try to use it on construction size lumber like 2x4. The bit pulls thru 2" side literally in seconds leaving relatively clean hole an not much splintering on the exit side.
To test this for splintering the work piece i have intentionally used a 7/16 " bit in thin particleboard. I the piece immediately cracked. Then I tried to pre-drill a pilot hole, the size of screw tip, before using Speedbor Max bit.
Under this condition the bit cut very nice hole without any tendency to split the piece apart. The hole was very clean with sharp edges and did not require a lot of force to push the bit into the board.
There are at least few issues however:1. Number of reviews indicated that the stem of the bit has twisted with use. This is definitely a big concern for me because I will not be able to use the bit for precision work if it twists out of allignment.
I have used the plug cutters several times. They bore flawlessly, but be careful not to bear down too hard with the drill press, especially when using hardwood. The resulting plug will burn, which becomes a problem regardless of your application.
The "small issue" is that I had not anticipated that the plug would be slightly conical and, for my application, created a more involved extraction from the bored blank. The resulting plug tapers from the tip to the base of the cutter, the largest diameter [of course] being at the tip, which is at the deepest penetration of the cutter into the blank.
I also assumed [prior to purchase] that the diameter at the tip of the cutter would be the identical with diameter of the hole I drilled in my application [both the cutter and the forstner bit I used are manufactured by Rockler].It was not.
Bought this as a Warehouse Deal. Only noticeable reason for a discount was some ruffled packaging. Bit comes with a replacement center screw. Easy and quick drilling in 2x material. Better control than I expected. Did run into one nail that I might have been able to drill through with a little more effort, but decided not to risk it.
The nail was reduced by half without damage to the bit, and after extracting the nail continued to drill without a problem. Cutting edges are pronounced enough that even if some damage had been realized it could have been remedied with an abrasive wheel on a Dremel.
I don't think the cutting edges could be effectively sharpened using a file since the room available to run a file at the correct angle is limited. A little pricey for my budget, but this is for a DWV project where the time saved compared with using a regular plug hole cutter justified the expense.
Its a great bit, but I don't have a drill that opens wide enough to run it. So I put a 7/16" deep socket on my drill and got going. I would not do this if I needed multiple cuts, but for my single cut purposes it was fine.
Notes: the kickback warnings are real. Nothing can prepare you for when these teeth hit the wood. My drill was not strong enough to make the cut but here is what I did. I used the center ping to outline the circle in the wood, then removed it.
The outline of the circle kept the cut true and the lack of the pin made the bit much less aggressive. I was able to remove less material over more time and complete my cut. If I had the right tool, I expect I would love this bit.
Excellent craftsmanship, great tooling , works perfect, heavy duty and spins true no wobble. I recommend getting this if you need a precise centered hole , I do a lot of commercial door hardware and count on the precision and reliability.
I used this bit to bore deep holes into pressure treated timbers. It worked very well. The cutting action is aggressive but still left a relatively clean hole. I used both a power drill and a hand brace to bore the holes.
When using a power drill I found that removing the centering drive screw from the bit reduced the aggressiveness a bit and made the cutting action finer/smoother. When using a hand brace, I found that putting the drive screw back into the bit improved the cutting action.
Thus, having the option to have the centering drive screw either in place or removed was a beneficial feature.
I bought this bit to cut a holes in two 5" x 5" x 2. 5" blocks of curly maple to hold a glass candle votives. The bit did a nice job cutting the hole, which was about 3/8" deep into each block. When done, the resulting hole in the center was a bit too deep and wide for my liking.
The completed candle votive holder turned out nice, but the center hole was very visible.
