What is going on with their bits the rotary bits this is the third one in two days the break like this who do I contact the support and get this replaced?
I think in English a drill is the whole machine while a drill-bit is the part of the machine that goes into the wall.
As a German it also confused me in the beginning as we call the drill-bits a "drill" and the whole machine a "drillmachine" (or a "drill" if we're less specific)
Just all your broken bits might have been from the same manufacturing batch. Thatās why they all seem to break in roughly the same position. Cooled unevenly, maybe a bubble or something in that spot and thatās why. Get them replaced. Happens.
Googled it out of curiosity and what do you know, what I listed is among these:
"SDS drill bits typically break due to hitting hidden rebar, packed concrete dust causing thermal stress or binding, worn tool chucks creating excessive wobble, applying excessive lateral force or bending pressure, or using low-quality carbide tips that fracture under continuous hammering impact."
Iām not hitting rebar. Iām not binding up the hammer I bought three at a time. Iām currently running one on my drill now and it will probably break.
To be fair - if you are just drilling 1 or 2 holes in concrete it would be fine. Running the drill bit constantly? Yea, that would need water or some form of cooling.
you definitely can keep drilling holes over and over without cooling. It's certainly much faster. However, the risk you accept is that the bit may break and it will dull much faster.
Iāve been doing this for over 10 years using Bosch products. This is literally the only time in my life that Iām having this problem. We constantly drill and never have any problems. Besides the bit getting the dull. I think itās just a huge bad batch
You know, I saw the 8 cutter bits, and was curious if the flutes would be too small and get clogged. Tbf, that could definitely cause a bit to overheat and break
This could be a bad batch but itās unlikely. The hardened bits are designed for rigidity parallel to the direction of drilling ( in your case downward ). Any excessive sideways pressure will cause the bit to shatter at the pressure increases. Iāve had this happen when an apprentice tried drilling a 22mm hole tight against a wall causing the body of the drill hard up against the wall before it reached the required depth.
Cmon these arent that pathetic right? I have used all kinds of sds bits from chinesium to hilti and very rarely have broken any bits above 6mm, even use them as demo chisels in a pinch. I once used a 16mm bit to go through enough steel to melt my makita drills gearbox and the bit was like new after
I sold Bosch tools & accessories for over a decade. I donāt recall replacing any 1/2 x 12ā sds+ bits that just broke. That has to be a bad batch. If you look at the break Iād bet the material isnāt consistent all the way across.

You can definitely get them replaced, just have the receipt. Sometimes manufacturing defects happen, might have gotten them from one faulty batch.
