how do i attach the drill bit to my dremel 300


You can use a drill that fits directly ( one size) or you can use a small chuck made for the Dremel. example: http://www.homedepot.com/p/Dremel-1-32-in-Multi-Pro-Tool-Chuck-4486/100531881

Cannot release tool from Dremel 300


I had a similar problem with a router, the best way to do it is to get a clamp, a strong metal c clamp, not too big but big enough to fit chuck into, line one side of clamp up with button and the other on the chuck. tighten the clamp as tight as you possibly can so it presses and holds the button in, and does not slip. Then use a wrench or whatever tool you use to undo the chuck. if this does not work, try spraying some WD40 on and leave to work for a few minutes.

i can not found screw to remove chuck what can i do then


It may just be held on by the threads and locktite. I just replaced one recently and it was just like that. The spindle shaft should have two flats on it. Use a wrench (you may need to grind down the thickness of the wrench to fit the shaft. And it is most likely metric) on the shaft. If possible put a large, l shape allen wrench into the chuck and tighten it. Place the tool on the ground and keep pressure on the wrench. I will often place my foot on the wrench to hold it firmly to the ground. Using a large hammer hit the allen wrench in a counter clockwise direction. The chuck will be right hand thread. IF it had a screw that would be left hand thread. After you give the allen wrench a few good hits with the hammer it should loosen the chuck. The chuck should be 1/2"-20 thread which is common on 1/2" capacity chucks. It should be easy to find a replacement chuck. Use blue locktite and reverse the removal process to tighten the new chuck onto the tool.

what keyless chucks will work on my makita hammer drill will a dewalt xrp chuck work on a makita


as long as the chuck is used for a hammer drill and the thread size is exact yes it will. I believe the thread is 1/2-20 and also make sure the chuck has a hole in the center for the reversing screw to keep it from loosening up. Let me know if you need more assistance. The thread size is usually stamped on the side of the chuck. Makita sometimes used a metric thread.
