Bosch HC8570 5 In. x 12 In. SDS-max® Rotary Hammer Core Bit

Good drill bit, works as advertised. Also purchased cutting oil which made cutting easier

This Bosch 2" core bit went through 10" of concrete with little problem. Drilled two holes in less than 20 minutes.

I bought 2 of these! A little disappointed with the grip of the carbide tips but I must admit that I gave them a hard time!! When used in new condition, it performs very well but as it drops off the peaks, the performance decreases rapidly. I am still satisfied with his performance with what I put them through!

Well worth the money. Chewed through a 6-8” slab fast.

Perfect for core drilling block to run pvc pipe through. Being a plumber, having to chip a hole through block to run pipes through underground is terrible. With this bit you simply drill a perfect hole, slide a sleeve through the block. Slide the pipe through the sleeve and you’re done. Great product. On hole #40 and still cuts great.

I used this in an attempt to bore 3 1/2" holes for a mini split AC unit. I hit rebar midway through the first hole. Helpful hint, turn off the hammering feature of your SDS Max tool if you hit rebar and try to slowly work your way through only drilling. I destroyed my first bit before I figured that out and had to buy a second to finish the hole. The second bit hit no rebar, but still had significant wear. I doubt I could have completed the second hole with the wear on the second bit, so I changed to a different bit. I bought a diamond dry core bit for less than half the price of this bit and it worked great. The diamond bit is slow because you cannot use the hammer feature and must only drill. However, it shows very little wear.

The media could not be loaded.  Went through 8” concrete like butter

Muy buena calidad y muy rapido

Excelente producto de muy alta calidad lo usare para meter tuveria eléctrica gruesa y para minisplit para sacar ductos y alambrado

The media could not be loaded.  Como cuchillo en mantequilla

Punched a 2” hole through brick, wood, and drywall like a hot knife through butter. Pricey but Bosch quality is worth it.

Does what it was intended to do and does it good as well as a fair price for it.

Great product. Bosch makes great products. I have used this probably around 15 time. Through 8 inch concrete wall every time. Works as well as it did when it was new.
