Question about Bosch 11240 1-9/16" SDS Max Combination Hammer

Open Question

The roto hammer (11220EVS) listed below periodically will go into a drill only mode (no hammer action) there is no switch to change from one mode to another on this model. Often just releasing the on-off button and restarting will cure the problem and then it works fine. What could cause this and what is the best way to fix it?

Usually replacing the o-rings on the piston, striker and Impact bolt will solve any hammering issues. That is considering there is no damage to the mechanical parts in the hammer mechanism.

Makita 4010 roto hammer, stuck in drill mode, cannot switch to hammer.


Here is the owners manual, page 5 and 6 shows how to switch modes. If it won't switch the you have some internal damage. The second manual is a parts breakdown. Concentrate on parts 63-79, and 160 http://powertool.manualsonline.com/manuals/mfg/makita/hr4001c_hr4010c_hr4011c.html?p=5 https://www.ereplacementparts.com/makita-hr4010c-rotary-hammer-parts-c-97_380_3717.html

My Hilti TE 17 roto hammer rotates but wont hammer


This one should have a knob or lever on the side of it to switch between "drill" and "hammer plus drill" It can be used as either a regular drill or a hammer drill.

Ok about changing the brushes but have you searched if the place where the brushes are located allow the brushes to move forward freely or they are in a way were narrowed so that the brushes can only move for few millimeters?

How to chisel


The Bosch 1199VSR Hammer Drill is capable of drilling or hammer drilling at two different speeds but can not hammer or chisel only. To do that you need a demolition hammer or roto/demo hammer tool.

Looking for some spare parts for this hammer drill...Is there any kind of web store or whatever that can ship worldwide spare parts for this machine?


It is very hard to find parts for tools made in China. There are many look-alikes all with different names. They could, however share parts. If you look on ebay searching "sds roto hammer" you will see many hammers that look similar, different colors. Take a look at the hammer listed below. It is a harbor freight tool. The parts may work. If you have harbor freight in your city, take a look (or on ebay). To order parts for harbor freight tools, look at manual for tool selected, there will be an 800 number to call.
