Excellent tool

Solid as a Rock!

I needed to revamp my sump pump setup which required boring one hole in 12 inches of cinder block and brick to accommodate a 1-1/2 inch PVC pipe. My first instinct was to head to the big box rental center. As I already own a SDS-Plus drill, I would only need to rent the core bit. It turns out that all the rental centers that I went to only had this size core bit in either SDS-MAX or Spline drive standards (they were very well worn also) which required renting a SDS-MAX rotary hammer together with the bit. I was put off by the high price that it would cost me to only drill this hole. I declined and headed home, determined to find another way. Long story short, I checked out Amazon and found that I could purchase the proper sized core bit and appropriate extension in SDS standard for the same cost of renting for 4 hours. I pulled the trigger and with my prime membership, 2 days later I was in business. The bit cut through my wall like a hot knife through butter. The bit and extension itself is high quality construction and you would not think by the description that this thing has a "thin" wall. It is solid and does a great job together with "Bosch T3926SC 13-Inch Extension Sds-Plus for Speedcore Thin-Wall Core Bits". It made short work of a cinder block wall with solid brick on the outside. It paid for itself in one use and has plenty of life left on the carbide tips. I can't argue with that.

Cuts masonry really fast, and durable

Display gave the impression it came with the shaft but I had to buy that separately.

Worked in stone

Make sure to pair with a bit. Bosch makes variations of this for all rotary drills. This is meant for a sds plus. I had concern that it would catch on an uneven edge of stone, dull, or crack the stone as it was never specified for such use. It cut through it perfectly. I had to use some sds chisels to pop out the core so I could keep coring. I suspected this would do the job as it was similar to other bits I use at work; however, gambling on a pricey bit and house wall concerned me. Worked great! I placed the vent in a smaller stone as requested against my caution that it might rip it apart since it was so small. It did not; however it did free it from the wall. I secured the stone when installing the dryer vent. Could probably drill most stone shapes, sizes, and arrangements just fine just make sure you have no electric in the wall.

Works as advertised

This product works as advertised and as others have reviewed. It does not come with the extension, so the product picture might be a little misleading to some. The description is accurate. The extension easily screws on, however, may be difficult to remove after use. Drilling through a 6" (or so) block wall (hollow) took less than one minute (approximately) using an old Harbor Freight Chicago SDS hammer drill. Drilling through a 6" (or so) block wall filled with concrete took about ten minutes per hole, allowing time for short breaks so the drill could cool down during the process.

Tougher than you would think

Bought this for a friend putting in a new drain field. He needed to put 6 holes thru four inch reinforced concrete to put in the four inch lines ... and yes, this bit wasn't deep enough for that, so he buried it, took it out changed to a chisel point, took out that piece, then went in again ... it worked ... I mean, he worked, I watched, I mean, what are friends for. And it took a LOT less time than I would have guessed ... still haven't gotten it to let me unscrew the centering bit ... but hey, I am still amazed and pleased with the thing.

Affordable Holes

I own several of the Bosch Speedcore bits in various sizes. I use these for installing dryer vents and PVC furnace vent piping. This 4 3/8" is a fairly large diameter bit to be driven by the typical SDS-Plus tool. As others have said, be patient. Go slowly and let the hammer drill do the work. Regularly chisel out and remove the chunks of "core" from the hole you're drilling before they can break off and bind your bit. And I recommend adding some Never-Seize compound to the threads of the pilot bit so you can disassemble it later. If your project involves drilling dozens of 4 3/8" holes in thick or reinforced concrete, then buy or rent a water-cooled coring rig instead. But for lighter-duty use, this bit does the trick at a great price.

worked well enough with underpowered sds-plus drill

I used this to drill a hole through 70year old corncrete/rock mix foundation 10inches thick, imo the hardest thing to drill though. Used a horrible freight cheapo 10amp chicago electric 1-1/8 sds-plus rotary hammer which is probably the weakest SDS drill around. Took me about 75 minutes. hole was pretty clean. Ive done the exact same job before using a sds-max with the homeless despot rental bit and it was 3x faster but the rentals are just as much as buying this bit+core. I would only recommend if you already have an SDS-plus and only want to drill a hole once in a while and dont want to rent/buy a sds-max. Makes a lot of dust, so be sure to filter through a cigarette.

I absolutely recommend it

I already drilled a few holes with this mostly for dryer vents, brick, concrete with my Hilti hammer drill. SDS Plus It worked great so far no complains. If it lasts a few more holes then it definitely worth the price.

Very good bit

The bit itself cuts through brick with ease (used with a Bosch rotary drill). But, probably due to heat and hammering from masonry drilling, it can be difficult to separate from the pilot bit. Not a big deal because it does come apart, but something to be aware of.

Very happy with this!

I bought this one to drill through basement wall. The wall is build of block and with my new Bosch RH228VC 1-1/8-Inch SDS-plus Rotary Hammer set to drill and hammer, it was very easy to drill in once the hammer function kicking in. I did let it rest for about ten seconds once in a while but the bit only felt lukewarm after use. I was thinking about renting a more powerful drill from Homedepot but they didn't have long enough drill bit plus it even if they did I will cost me almost the same amount of money for only one hole.

Slow and steady…

price and delivery good. Slow to drill in granite with a medium-size SDS+ hammer, but it gets there eventually. Obviously, that is not the fault of the merchant... I am looking forward to better performance using a new SDS Max hammer.
