Do these work with the Milwaukee quick lok

Asked by AR March 27, 2021

Answer

I'd say yes. I've used this auger bit in both a std chuck and and 7/16" quick-lok "hole hawg". It's a bit of a lose fit though IMO as the bit will deflect a few degrees when pushing through at the end of a bore.

Will this fit a 3/8 shank ?

Can this bit be usedcto drill railroad ties?

Asked by Jch92592 February 19, 2021

Answers

That should be no problem providing that there are no embedded rocks in the railroad ties which unfortunately has been my experience a few times. But yes concerning actual wood this should chew right through that no problem.

How long is the shank of the bit? What is the useable length?

Asked by Customer July 9, 2020

Answer

Hello, Thanks for your question. The shank length is 2 inches and the usable length is 5-1/2 inches. Hope this answers your questions. - AM

I'm a residential electrician, have a lot of drilling in new homes. I purchased this bit hoping it would perform. It did not. The bit is labeled as nail embedded wood, the first bit I purchased made it through 2½ houses before the tip snapped off, making it very difficult to finish the job. I then exchanged it for a new one. Out of the package it made 13½ total holes before the tip snapped again. I'm drilling new 2x4 and 2x6 some with nails from framing. Soft wood. It touches a nail and it's broken. Would not recommend or purchase again.

I bought this auger for our technicians who routinely have to drill into utility Poles to mount hardware. So far so good. Very sharp and chews through wood very quickly, time will tell as to how long it stays that way. Really can't go wrong for the price and being available at your local home depot store.

I was experimenting with a way of adding low voltage lighting to 4x4 fence posts. I wanted to hide the wiring inside the posts so I needed a long drill bit. I choose the Diablo 3/4 in. Auger bit as I felt it would get the job done and be versatile enough for future projects (Tree house). Boring diagonally, the bit came out about 10 inches down, but straight down it reached 15 inches. My plan is to run the cable though the PVC railing and then down the inner wooden post about 10 inches. Note: The bit cuts fast, after about 5-6 inches I had to back it out to get all the chips out before continuing.

I occasionally need long reach wood bits and this Diablo 3/4 inch x 17.5 inch bit will come in handy. It has a 7/16 hex shank and bests works in a drill that you can operate with two hands because of the extra torque it takes to drill a 3/4 inch diameter hole in most thicker woods. The 7/16 hex shank worked perfectly with my quick release 7/16 hex shank drill. You could use this auger in a lighter drill, if your drilling thinner boards or drill slower. The maximum listed RPM is 600. The auger is designed for nail embedded wood/boards and seems very durable and strong. Overall I am very pleased and expect to use this auger bit for several years.

Great ship auger. I drilled through a cured maple log no problem. The bit was still sharp and the pulling threads on the tip were too. It then drilled clean holes through studs without splitting them. This is designed to work with a quick connect drill chuck or regular chuck. It comes with a decent case that holds the base secure so that the bit tip doesn’t poke a hole in the end of the case and become exposed.

I don't use auger bits on a daily basis. I got this one because of it's length. I've got a special project where I need to drill 3/4" inch diameter holes lengthwise about 16 inches through 4x4s. This bit keeps its edge so much better than the cheap, no-name brands. After 25 holes, it's still cutting like brand new. I love the carrying case. Throwing an expensive bit in the bottom of my toolbox bothers me. If I invest this much money, I don't want it getting damaged by other bits and objects. There is nothing wrong for me to report. Just a heads up, this large bit will drain 18V batteries quick. If you intend to drill many holes, go corded or have a few batteries as backup. Next thing, because of its length (contact surface area), it can bind. If your drill has a side handle, you may want to attach it out and avoid high speeds.

I needed a long auger bit to drill through several garage door headers prior to wiring up some can lights over the doors, so I decided to give this DIABLO 3/4 in. x 17-1/2 in. Auger Bit a try. The long length of this bit makes drilling overhead through a thick header easy and convenient. The bit is self-feeding and bores through framing lumber almost effortlessly. Waste is pushed out of the cutting area efficiently so the bit keeps going without frequent removal to clear the chips. This bit is rated for use on nail-embeded wood, so it is appropriate for a range of electrical and plumbing projects. I've owned a number of Diablo bits and have always found them to be strong and long-lasting. I'm pleased with this product - highly recommended!

This one of the best drill bits I have ever owned. Goes through hardwood without putting pressure down on the drill. Stays sharp so far. Holes are smooth and not ragged as some other bits. Carrying case to protect the bit is a great addition. Flat spots on the shank that make the drill grab and get full power without slipping in the Chuck. I highly recommend this bit!

The Diablo 3/4 inch x 17 1/2 inch auger bit is a great auger bit for drilling deep holes needed to run electrical cables and copper and plastic PEX water pipes. The long bit makes it easier to cut through multiple floor and wall joists where two or three beams are between floors. The Dura-Tip makes starting holes easier and more accurate. Dual cutting edges make cutting easier and help move wood chips out the deep flutes on the bit. It's never a good idea to hit a nail when drilling if possible but this bit is durable enough to be used in nail embedded wood. A heavy duty 1/2 inch drill is almost a necessity as this bit really grabs into the wood and moves quickly. The hex shaped shank on the bit locks easily on to the drill chuck and wont slip under heavy loads. You can feel the high torque as it cuts and a two handled drill would be recommended. I have used similar types of long drills, both regular drills and spade bits but this auger type is the easiest and quickest way to get the job done. I expect this drill bit to last a long time

DURABLE I received my Diablo auger bit today; it measures 3/4 in. X 17-1/2 in. long. This auger bit will work in wood with nails, which is a useful feature for any auger bit. I use these Diablo auger bits to go through garage door headers to add electrical, usually for coach lights. I have found any cutting tool made by Diablo works exceptionally well. Overall, these auger bits are long-lasting and cut fast even in nail-embedded wood.
