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 11.
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 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.

Rated 5 out of 5 by from great buy Designed for chiseling and breaking brick, concrete and loose stone. We need to remove a side walk about 3'x 4' and it worked great. It retained its sharp chisel edge and i still use it today for all kinds of jobs where chiseling is needed. I would recommend this Steel chisel rotary hammer drill bit to anyone. This tool will do the job and fast. Very happy.

Rated 5 out of 5 by from Good Choice Having a selection of bits for my hammer drill the last two I purchased were Bosch and I have been very happy with their performance and quality. I used the curved chisel for removing commercial grade tile (ceramic and vinyl) and was amazed how it survived and maintained its edge.I used this model to chip out a pathway for a new drain in what appeared to be hardened concrete and it held up and also maintained its edge.Quality, commercial grade bits.

Rated 4 out of 5 by from Strong Durable This bit works fine knocking off old thin set from tiles I've removed. Makes quick work of the job and seems to hold it's edge fine too. The only problem I have is using it in a Milwaukee hammer drill. I can't get it in straight because of the grooves made for a Bosch rotary drill. It still works fine for the job I'm using it for even if it isn't sitting square in the drill. Still a nice bit to have and use.
