Customer Questions & Answers

can you sharpen them and how

Asked by: cj
Thank you for your question. We do not recommend sharpening the HS1420 bit, it would cost more than purchasing a replacement bit.

Bulldog 3/4 in. x 10 in. SDS-plus Hammer Steel Rotary Hammer Chisel for Concrete and Masonry Demolition is rated 4.9 out of 5 by 12.
Rated 5 out of 5 by from Great Chisel This chisel bit works great in my Makita rotary hammer, and still super sharp after several uses.

Rated 5 out of 5 by from Light, but heavy duty My only previous experience with SDS bits and chisels was with the chinese harbor stuff, on a Milwaukee 18v Fuel rotary hammer. The experience was underwhelming. I got this Bosch 3/4" x 10" chisel in anticipation of a Milwaukee 28v Fuel rotary hammer -- huge difference. Went back to a chinese harbor chisel -- the Bosch feels like titanium; the HF bits and chisels are definitely heavy steel. In concrete, the Bosch seems to worm its way into it, it feels like more of a controllable tool vs the HF blunt mallet. Bosch makes more of a precise cut; HF just destroys -- glad I have both, but I'll be looking into replacing my HF bits with Bosch's.

Rated 5 out of 5 by from Chisel I am replacing the crawl space vents in my foundation and needed a chisel that was strong enough to break small amounts of concrete to make room for the new vents and this is doing exactly what I needed it to do. It is a bit more chisel than I probably needed but it is working great. It is sturdy and easy to use. I definitely recommend getting it if you need to chisel concrete.

Rated 5 out of 5 by from Great Tool! This tool saved me countless hours and fatigue from removing old concrete fence post footings that were left in the ground at my house. All I had to do was dig around them enough and use this chisel to fracture the concrete into chunks. It was so easy I couldn't believe it. t used it with my Bosch Bulldog Xtreme (another excellent product).

Rated 5 out of 5 by from TO THE POINT Just what the Doctor ordered for taking out that stubborn cement that has been cracking for the last year. Fit it in to the hammer drill and put it on the concrete and away she went, Safety Glasses were needed to keep the chips out of my eyes but boy did it turn the concrete to dust and small chips and it retained its sharp chisel edge. I highly recommend this tool for anyone that has a 3/4 hammer drill. It does the job, strong steel and sharp.

Rated 5 out of 5 by from A handy tool to add to any collection. This bit I got to open up the seam in my garage floor to the apron so I can fill in the crack and keep water out. Using this bit with your sds hammer drill is like having a miniature jack hammer. This bit could also be used to chip off welding slag and spatter. My other project I got this bit for is to help me to split up a large rock, I can use this bit to help push in the wedges into the drilled holes.

Rated 5 out of 5 by from Excellent bit I've got a bunch of Bosch large boring drill bits, and SDS Max bits, but this was actual my first SDS plus bit from Bosch. Very solid, just like a smaller version of my SDS Max chisel bits. Good weight, good edge, which I'll have pounded round in no time... Just kidding, I've had the same Max bits for years. If this lasts anywhere as long as my Bosch boring bits, it'll be a great deal.

Rated 5 out of 5 by from solid! This bit is solid and well engineered. It slips into the SDS mount of my Rotary hammer drill (Milwaukee) easily. It was very quick at removing cement from some old firebricks that I am recycling to make a BBQ. My next task for it to to break up a cement walkway and I am confident that it will work without issues. Packaging is simple and easy enough to open.
