Question about Makita HR2455X 1" Rotary Hammer Drill

1 Answer

Bits will not lock into chuck

Difficult to pull back to open chuck. The bits will not lock into the chuck. Is this a situation I can fix or do I need to take it to the shop. The HR 2455X has been used very little. Thank you for your help.

First I would go to Makitatools.com and download a schematic for this tool. But it is pretty simple to remove the rubber dust shield and plastic collar to look for debris and proper movement in the chuck assembly. Make sure also that you are using the right SDS bits in tool. You should be able to push the bit into the collar and twist until it goes into and locks. Let me know and I will help further

The bit wont lock in the drill, how do i fix this problem


This is a very easy fix - you have a quick change chuck on this tool. Turn the chuck counter-clockwise and pull it straight off - the new one goes on the same way. Quick Change Bit Chuck

Bosch 11241EVS won't hammer


Not all bits for hammer drills are the same as the slots in the sides of the shanks are different between makes . There is a standard between hilti and ramset drill bits but other makers have different ideas Check out the shanks of your drill bits and look for the slot that holds in the bit.

Cordless sds leaving grease on sds bits


There is supposed to be grease on the chuck end of SDS+ and SDS Max bits. Actually, you should put a little lightweight grease on the end of the bit every time you put one in your drill. If you, or noone who has ever used the drill, have ever done this, it is possible internal grease is leaking out of the drill and it should not. There are seals to prevent internal grease from getting out of the transmission and striker mechanisms. If you are loosing internal grease, these seals should be checked.

I have a hitiachi DH38ye drill and it won't accept the Bosch spline bits. they go in ok but the chuck won't lock. The drill accepts the hammer bits fine but won't accept the drill bits


you have me stumped on this one. The tool you have is a spline shank hammer and it should accept all standard spline bits and also hammer iron that is made for these. Is it possible that the Bosch bit has a burr on the splines not allowing it to lock? I have checked the Hitachi site and found no reason it would not work. I will continue checking though.

There is play in the chuck may be bearings. it means drill bit wanders slightly when drilling. drill bits lock in properly but the chuck has left to right play in it


You seem to have found the problem, now you must disassemble the gear head and remove the chuck. Open the chuck jaws wide and look for a screw inside that locks the chuck to the shaft.

Drill bits do not lock in chuck or will not go in at all.


If the picture that I am seeing is of the same that you have then I can tell you that those are special bits that are fluted on the shanks so they can hammer. Also those drills do not chuck up like a regular drill. You have to pull the collar down insert the bit and rotate it until it falls in and then release the collar. Remember these bits are specific to the drill and can be hard to find, a rental store is a good place to find them for sale. Hope this helps. 2rns4u <*{{{>(

Drive systems Question


SDS (or Slotted Drive System) bits for hammer drills/rotary hammers allow the bit to slide in the chuck and enhance the hammering action of the tool. For most applications, these bits provide plenty of torque. SDS Max bits are similar to SDS bits, but have larger shanks and come in larger sizes than SDS bits. These powerful bits are useful in industrial applications.
