Steelex D3654 4-5/8-Inch Heavy Duty Forstner Bit with Screw Tip , black

Tough tool

I decided to risk it. I'm making a wine rack, by drilling 3 1/2" holes into a board, then cutting that board in half. I started using a traditional hole saw, and I drilled 7 hole (with two different drills, because my cordless drill conked out), and it took me about a half hour. Got this bit, straight out of the box, and cut 6 holes (one tester in the scrap end of the board) in less than 3 minutes. Battery on the Milwaukee is a 5Ah, and it only drained 1 bar with 6 holes. That's pretty good! DEFINITELY USE A HANDLE!!!! I tried this with the drill clutch, and it would just stall. Put the handle on and held it steady, and it drilled itself right through.Will this work on nicer hard woods? No idea. If you need it to slow down, drill a pilot hole of about 1/4", and it won't pull itself through as fast.

does a fair job of boring out hole except you have to bore out smaller holes first before using the size

At first glance, these bits seem great. the longer, adjustable self-tapping tip looked like exactly what we were looking for. But the steel was cast very poorly. the shaft was snapped off twice by a 3/8th inch battery powered drill. And these sized bits are intended for much heavier duty applications, like a 1/2 inch drill. after looking the breaks over, you can see the new breaks, but you can also see where the metal was not cast properly and a different color, not shiny like the fresh break. We called the number on the package, and the customer service was completely useless. We were told to contact Amazon, but by the time we even used this bit, the return time had passed. Do yourself a favor and by the not heavy duty bit sold here, its well made. This one is not.

We’re building fence posts on our property and this device turned out to be absolutely incredible… I recommend anybody with a large ranch to consider this tool for rebuilding your fence.

If you've never tried a Forstner bit like this for drilling large holes, you should. Compared to a hole saw, this thing is a monster. You need to have the right drill for the job (big) and the right angle of attack (straight) but one it gets going, it doesn't stop until it's through whatever material you throw at it. No more leaning on drills and getting fatigued. Just line it up, pull the trigger, and hold on. This one in particular made QUICK work of a few joists to run conduit. Truly worth the investment over a hole saw. The adjustable tip is nice as well, since each job is slight different. I really have nothing bad to say about it.

Worked great once I tightened the drill bit in the center drill bit. Mine was loose and pulled out stopping me from finishing the hole. The drill bit is adjustable. Just make sure the set screw is tight. Also have a good drill press. Mine was not powerful enough to finish the hole it in one pass. But it did just what I wanted. Only wish I had a stronger drill press.

These Forstner Bits did not impress me at all. They are caste metal. They need a lot of clean-up and sharpening. After that they work fairly well. The few times I will use them on my lathe I will keep them. You could not make a living using them.

Worked great for installing my treehouse attachment bolts. It killed my old cheap drill. Purchased a quality high torque drill and this bit zipped through the wood. Quality seems like it could handle lots of use, but so far I've only needed it 6 times. For the price, it was well worth it.

work good in softh wood but in hard wood just burn stop cut

Worked great. I went 3" deep into a solid whit oak tree to install 2 tree house attachment bolts. It was work, but the bit held up well and still looked nearly new one completed.

The bit did the job just like I expected. However the set screw vibrates loose and should be checked periodically. The screw tip is excellent for centering the bit and keeping it on track. I found that a drill of at least 9 amperes or greater to do the job for cutting smoothly. Gives quite a work out. I used the bit to build my log spiral stairs and was happy with it.

Definitely heavy duty! Comes with a spare center pulling screw and the Allen to replace it. Obviously not high quality but im not going to use this professionally. Perfect for the little jobs I got to do.
