Bosch HS1427 SDS-Plus Hammer Shank 2-1/2-Inch by 10-Inch Wide Steel Self-Sharpening Chisel , Silver

Worked well (homeowner) for removing both tile and glued laminate flooring from concrete slab (~ 500 sf), used horizontally to lift up tile from underneath. Also good for removing residual grout & glue globs to smooth slab prior to re-flooring.Worked much better and cheaper with MUCH less dust than a jackhammer, that a bubba contractor used to remove the same tile at (another location on the same slab.

This worked really well for taking up old tile. It even helped remove some adhesive that was there from a previous vinyl floor that had been on for years. I still had to scrape up some remaining adhesive to prep the concrete floor for new tile but this helped make my life much easier by getting about 50% of it up. This is a well made shank that stayed sharp after using it for several hours.

Very useful tool. Electrician by trade. I use this tool a lot, from punching out holes in boxes to actually demoing concrete.

Solid and quality steel. Yet to use but I did install in a bosch hammer drill. I could not install bit at the head angle I desired. The shaft locking mechanism allows only one angle. This will make chisel work cumbersome. If allowed, I will edit this review once I actually hammer-chisel the concrete and mortar and bricks as originally intended.Update#1: changed stars from 3 to 4, after 5 minutes of hammer chisel use. I was able to change the angle of the chisel head using the Vatio-Lock on the drill. It allowed the head to be placed at any angle. I then moved the adjustment dial to "hammer only" to lock the chisel in the desired location.

Have the smaller one i've used to bust up tile and chisel thinset with on many rooms. Got this for large bed and bathroom and it's so much easier with a slightly wider chipper (on a bosch bulldog). chip out your tile, couple perpendicular passes with the bosch, then plane ol floor scraper steel blade to get what little is left. Made quick work of it.

Putting in a drain line through an ancient hand-laid stone wall; I had to make a hole.The stones at the foundation level were huge I bought this to put in my big dog Bosch hammer drill. Using a high end German bit I put a slew of holes in the offending boulder and with this wedge shaped chisel in my hammer drill it cracked the piece of boulder away so I could lay the 4" drain.YippeeThere was no room to be using wedges and a hammer.

Used tool in the past, last long time

I bought this for my SDS rotary drill.The soil here in Tucson is hard as a rock, but this chisel cuts through it nicely. I have dug deep holes for three cacti and another plant in order to fill them with soil amendments. My neighbors simply dig a vey small hole and put their plants in. I come from a long one of Midwest farmers and have to do it the right way. This chisel really helps.

no sirve para romper piedra, se pone la punta roja (se calienta y llano perfora)

Worked great. Spent an afternoon scraping old carpet glue off a concrete floor. Went down to the concrete easily.Still in very good condition with minimal wear. If I ever wear it out, I'll buy another one.

The chisel has worked great for breaking up concrete steps and a couple of walkway poured concrete sections too big to remove without doing so. I've used its conveniently shaped tip to speed along some brick-pointing jobs as well to good effect, still looks like new. It fits in an SDS-plus tool, in this case the Bosch Bulldog Extreme. That's designed as a mid-range rotary hammer, so keep in mind the kind of projects you should expect to use this chisel on.

its works good and im happy
