Insert sds bit into chuck with slots/slot matching slot in chuck while pulling back on the spring loaded nose. If the bit does not catch try turning/rotating bit to lock. When you release the nose, a pin will drop into the indention on bit and prevent it from falling out during use. Sometimes this pin will break or wear-out thus the bit will not catch. Before you insert the bit, look into chuck for retaining pin. Pulling back on the spring loaded chuck releases pressure on the pin and allows insertion of bit.

How do you put a router bit in a Makita router model 3612BR


Inserting the bit should be the same on all versions of the Makita 3612 router. It does depend on the bit size. Press the shaft lock to keep the shaft from turning. I think the lock is close to the handle on one side of the router when you hold the router with the bit/collet up. For small shaft bits, insert the appropriate collet sleeve into the collet cone. Then insert the bit completely into the sleeve. For larger shaft bits, insert the bit completely into the cone. Use the wrench to tighten the collet nut securely. Unlock the shaft lock. Do not over-tighten or leave the bit loose in the collet cone/sleeve. Over-tightening can break the collet cone. Leaving it loose can result in the bit flying out of the collet cone. Either way, injuries can occur. To remove a bit, loosen the collet nut and then remove the bit (or bit and collet sleeve).

The manual is available on the product page: https://www.makitatools.com/products/details/3612 . The direct link to the manual is https://cdn.makitatools.com/apps/cms/doc/prod/361/df12a409-2bd0-48c3-aa38-d635a480a76e_3612_IM.pdf . See page 8.

I hope this helps.

How can I replace the ignition lock and the drivers door lock on a 1993 300zx?


You will probably need to drill out the center of the ignition lock cylinder to remove it without the key. Start with a small bit and make sure you drill straight into it and then use a little bit bigger drill bit. Keep doing that until you can turn the key lock cylinder and you'll be able to remove it.

How to get my ignition lock out


Instructions

Test fit a drill bit in the lock cylinder. You want a bit that is just smaller than the cylinder. You will be using hardened drill bits to cut through the cylinder, since ordinary bits may be damaged by drilling metal.

Lock the drill bit into the drill chuck and tighten the chuck.

production in very fast delivery! special threading taps, plug gauge

Drill a starter groove into the lock cylinder. Start the drill on a low speed and create a groove in the end of the lock cylinder. You don't need to create a deep hole, just enough of a groove so that the drill bit will not slip on a higher speed.

Increase the drill speed to the highest setting and drill out the lock cylinder. Let the drill do the work. If you force the drill into the lock cylinder, you could burn out the rotor inside the drill motor

DC212 does notlock the bits


First are you using the correct SDS style bit? They do not use just standard drill bits. They have two long cutouts on each side and two oblong ones on the opposite side. You should be able to push (and rotate to line up the slots in the bit with the tool) the bit in without touching the bit holder and it should lock into place. You push down on the holder only to release the bit. The holder is spring loaded with a small metal ball that contacts and holds the bit at one of the oblong sections.

How do i change the bit on router?


On my older Sears router there is a lever on the base near the collet nut that you slide to engage the motor shaft to lock the motor shaft for bit changes. On newer models you may have a button or different mechanism to lock the shaft. After the shaft is locked you can use a small wrench to loosen the collet nut, usually by turning it counter-clockwise (viewed from the base). Once the nut is loose the bit should slide out (sometimes the bit is stuck in the collet and the nut may need to come all the way off to get them apart). Just replace the bit with a new bit with the same shaft diameter, tighten the nut, and you are set. If the new bit has a different shaft diameter than the old bit you may need to change the collet also (in general, different collets are used with different bit shaft diameters).

I borrowed a black and decker rotary tool (RT 550). I can't seem to get the bit off or be able to change bits. There is no tool to use to open the bit and everywhere on-line it says ''quick swap of bit...


slide the orange on/off switch all the way back then push in the black button the switch slides over. This will lock the shaft-then use small wrench provided w/ tool to turn the collet nut

I need help on how to replace bit on router craftsman style


You didn't state the model number. The older Craftsmen routers had a red lever lock on the top of the router, one position allows the spindle to turn, the other position locks the spindle. Here's the instruction for the older style routers:

  1. Unplug the tool.
  2. To lock the spindle press the red button in and slide it to the locked position.
  3. Unlock the height adjustment knob.
  4. Raise the router motor using the height adjustment collar until you can get a wrench onto the collet nut.
  5. Loosen the nut until it turns freely.
  6. The bit may still be locked in the spindle, tap it gently (not on the blade!).
  7. The bit will come loose in the spindle and can be removed.
  8. Replace the bit, tighten the nut snug but don't use excessive force.
  9. Unlock the spindle, returning the red lever/button to the free position.
  10. Adjust the height of the bit as you wish, then lock down the motor using the locking knob.
