IRWINSPEEDBOR Tri Flute Wood Drill Bit 5/8" X 6"(3041002)

I've had good results with Irwin bits in the past, and this was no exception. I look forward to buy from this seller again.

We use this bit to blow rebar holes through 2x6 forms. We want the fastest cutting bit we can find and this seems to be about it.

Great drill bit!

This bit is great for what it is intended to do! Bits that have a screw on the end that helps pull the cutting edges into the wood are really helpful for HAND drills because they are a lot less work for the user. Otherwise, you'd have to put a lot more force on the drill to get it to bore. It's essentially a modified auger bit. Drilling by hand is a lot more effort than pulling a trigger, obviously, but, it allows you to go slowly, accurately and gives a really nice straight cut, if you are careful. This bit does this really well, though it could be sharper from the factory. It's a bit rough, but for this price you shouldn't expect a top quality bit. You could easily pay upwards of $30 for a top end auger bit to do what this one does pretty well. So, sharpen it up yourself carefully and you will be glad you did.However, if you use this with a POWER drill - it can take off on you because the screw will pull the drill bit into the wood REALLY fast, or puil the board into the drill if it isn't clamped down securely. Neither of these options is a good one for the user or the project. And these type bits cut fast! So, you can really create some dangerous situations if you misuse this type drill bit. I thought that needed saying as there seems to be some confusion about this bit in the reviews. Many people are not familiar with this type of bit or how to use it properly. If you want to use it with a power drill, make SURE it is a high torque, variable speed one and go REALLY slow. This is a bit that cuts fast at hand speeds. Otherwise, the drill will do what it does on its own and you will be along for the ride. This is used completely differently from a spade bit where you want it going fast. Definitely do not use this type of drill bit in a drill press! Bits with this type shank easily wobble loose in a drill press designed for round shafted bits. Also, can be very, very dangerous....That said, I managed to repeatedly cut through 3 inches of solid pine with this bit using a pawn store hand drill and was amazed at how fast it cut. I was sweating after the first few, but it wasn't too bad. And it's summer... I'm building a cheap and very clever modern version of an English Joiner's bench a guy has a video and free rough plans for on youtube and bought holdfasts that require a deep 15/16" hole. The bench is amazingly solid, but takes some work to build, obviously, and I modified it to suit me.... But, a really solid workbench for less than $100 in wood and bolts is pretty good and it will do everything I need it to do really well. I didn't have the right sized bit, so bought this one. Very glad I did. That's a lot of big holes to drill. And they need to be straight. It worked like a charm. Great bit, really. Well worth the money if you need one. The holdfasts work great, too! So, no complaints. Be careful out there.... Power tools are awesome effort savers, but they are dangerous as all get out if you don't know what you are doing, or you have the wrong tool for the job. FWIW... YMMV

Very nice bit for the money.

Drills fast and leaves a nice clean hole. Much faster than a spade bit. When you have a lot of holes to drill and haven’t got all day use this one.PS: It didn’t work well in a drill press.

Bought this 1-1/4" drill bit to cut holes for running an electrical line. The bit is made very well. However, it sticks a bit if you apply a little too much pressure when drilling and I kept having to back it out. I found that its easier to use by first drilling a center hole with a 1/8" drill bit, this helped quite a bit. As you can see in my pic, the holes turned out very clean. For the money, I would recommend. Hardware stores are twice the cost.

It works way better than the flat spade bits of the same size.

If you need a hole drilled in a hurry this is your bit. It will tear though a stud at an amazing pace. Watch-out though, if it binds it will twist the drill right out of your hand. A high speeds it tends to tear the wood so I usually use a slower speed. I will buy a set next but for now I just need this specific size for a specific project.

Used this to drill holes for running wire. Easily 100 holes drilled through 2x4. Requires a push to break through other side (expected, as the threaded nose is no longer grabbing into anything). There was some blow-out, but clearly this is not a fine woodworking tool so no problem. Drills FAST (recommend using a corded drill for extra fast hogging power).My own fault though, I hit a nail. And although it still hogs out the holes - now the blowout is really noticeable.

The description and picture of this speedbore said 1/4" shank which should fit into my impact drill. When I got the bit, it was not as described. The shank is actually 3/8 and will not fit. I can still use this but I feel like I was mislead. Don't know what to believe now. Won't buy this online again.

I've tried a few of these self feed auger bits, theres better quality and also cheaper but these are very good for the price and better than some that cost more. The Milwaukee bits are more than double and these would last nearly as long.

The bit will be used in cutting holes in 2x6 for wire to go threw.
