Borrhammare

Always let the machine do the work. Just have to hold down enough to stop the drill from bouncing = sweet spot. Cheap drills, have tested more expensive but cheap will do the job as long as they are straight.

Couple of years since I bought it but should be something like this:
www.jula.se/catalog/verktyg-och-maskiner/elverktyg-och-maskiner/borrhammare/elektriska-borrhammare/borrhammare-011637/
Use google picture search and you probably will find similiar local china brand. This one don't have reverse gear which is a disadvantage when stuck. Have revearse on my cordless Milwaukee.

@@roger-youversionbibleappus3554 No it was more of a test :)

Uh,. nu var det ett tag sen jag borra men med kil brukar det var +2-4 mm, helst info från tillverkaren.

Äkta Jula, borr från Lidl.. Jula har/hade? en modell större men där löd kommentarerna ungefär:
-Bra drag, motorn brann upp efter 18 hål.
Denna kämpar på bra ännu, svetsade ihop några järn på en borr i vintras i försök med att skrota inlandsisen i backen hemma. Gick sådär men inte maskinens fel, måste varit luftfuktigheten och blixtrost för fogen höll inte...

No idea, std-sds? Ask that google machine =)

@@hochimin1584 Will do the job as specifications, no reverse is the only disadvantage really. Good machine for the money. Now I also have cordless Milwaukee, don't hit as hard as this but faster = same same. More expensive and with reverse =)
