I have a large slab on grade floor to trench to completely change and move around the plumbing drains/vents ect. I plan on cutting the trenches in the 4" thick non reinforced slab with a concrete saw and then jackhammering.

Is the Hilti TE 905 potent enough to handle this job or should i rent/buy a 90 lb. air jackhammer.

Get an air hammer, electric hammers just can't compete with a good air hammer.

A 905 might be a quick n easy way to knock out a couple yards of 'crete, but beyond that....... call in for some air power.

they have a Te-1000 i have seen it compared to a air hammer. It is cheaper than the 9 and 8. It destroyed the Bosch Brute and Dewalts large hammer head to head, and one guy sent his compressor back to use the 1000. Sometimes it is better than a beat up rental air hammer i guess.

haven't checked out the Te-1000 but I own 3 almost new TE905s and they are very good hammers for the money..I paid very little at a guy's estate sale..

The new Makita HM1214C AVT is a better option if that is the size you want. The Makita HM1810 is also a great breaker hammer for that size. They are both much less expensive than the Hilti equivalent and have anti vibration that is above the Hilti.

It all depends on your slab..

If you can saw cleanly through (4-6"), the hilti will quickly snap the cutout into manageable pieces.

If your saw cut's a little shy, you'll end up pulverizing to get it out. Then I'd rent a big electric.

I've done a LOT of this with my ts400 stihl and a te76 (i think). I've even put duct work under a slab this way:shutup:

edit: IMO Hilti makes the best electric rotary hammers.:thumbup:

I own several Hilti tools.....My favorites are the TE 76 and the DX 460 for sill plate shooting.

I would not have even considered a smaller jack hammer for this job except that the Hilti's i own impress me and i was trying to talk myself into buying the Hilit even though it probably isn't the best or fastest tool for the job I'm faced with.
