Bosch 11230EVS 1-1/2-Inch Electronic Variable-Speed SDS-Max Rotary Hammer with Stop Rotation Review

Average Reviews:

(More customer reviews)Rotary hammers are a big buck item so its important to consider all of them. I use this Bosch hammer in my electrical contracting business. Its small enough to handle easily and it is built to minimize the vibration that comes with drilling concrete. It can drill through concrete up to is specification and handle ground rod driving too. Buy this unit and the Bosch bits but consider the DeWalt accessories, like ground rod driver or spade bit, because they are usually less money.

Makita HM0810B 11-Pound Demolition Hammer Review

Average Reviews:

(More customer reviews)the HM0810B is the best, lightweight hammer on the market. 2900 blows per minute, with a weight of only 11.7lbs. This is the hammer that should be used for chiseling, chipping and scaling, NOT the HK1810, which should only really be used for removing tile and plaster.

Hitachi DH38YE 1 1/2-Inch Spline Rotary Hammer Review

Average Reviews:

(More customer reviews)Like most Hitachi tools , this is very well engineered. It stands up to all kinds of abuse. Mine ran for years drilling all sizes of holes in old hard concrete. I also used it for chipping which is hard on roto hammers. They don't have a lot of power for breaking concrete as this is not their intended primary use. So when you do use them for breaking , they have to run a lot longer than a demolition hammer would. It has pretty good power for drilling though. I bought mine used and had it for five years before replacing it recently. I went to SDS max which is currently replacing spline drive in the large rotary hammer market. It is a tighter mechanism which transfers more of the hammering power to the bit , resulting in faster drilling performance. If you have a lot of spline bits , this would be a good tool to buy. If you are starting from scratch , I would recommend the SDS max hammers from Hilti , Bosch or milwaukee
