dremel care – cutting guide

Posted in note to self, tools, Uncategorized with tags on January 27, 2017 by marksun

Note to self – I use a dremel all the time but have done a not so good job of taking care of it.  I mostly use a variable chuck – very convenient –  fits 1/32 all the way up to 1/8″ – I recommend it but there’s a downside.  The collets are forgotten and the plastic nut that goes over the tool nose is long lost.   Today I  used the dremel cutting guide to cut a recess into a wood panel.   The guide requires using a collet and the chuck had to come off.   Which brings me to care of the tool.

This is a note to self for the dremel on stuff I don’t know or had forgotten.   The dremel shaft is hollow, the collet should drop or be easily pushed in all the way to the chuck.  It should come out easily.  If the collet doesn’t drop in easily, there is probably dirt, grime, or rust, all of which you want to get rid of immediately.  As you know rust will ruin the tool – useless once the collet is rusted in and will not come out.  #1 son has a couple of dremels like that.  So that dremel chuck shaft needs to be kept clean, and protected with a light machine oil or corrosion block.

The collet shaft is inserted into the dremel shaft and drops all the way down to the chuck with its four thin slots which provide the clearance to allow it to be tightened down.  The collet nut fits over it.  The bit can be inserted with the nut on or off.  The collet should remove easily and be maintained.

The collet nut fit over the collet and shaft and screws in.  It too must slide easily without binding.  Better to grease it than to have rust.  I used corrosion block to clean up and protect collets, nut and dremel shaft.

There are four collet sizes.  We use 1/8 the most for biggest bits.  Although I use the chuck most of the time, the collet system is nice and we’ll be using it periodically to keep everything in good order.

Found the manual in my drill tool box.  It shows how to use the cutting guide.  The cutting guide is easy to use but I had to see a you tube video for a picture of how its used.  Typical,  I thought I know everything I needed to know about the dremel but I don’t. Anyway, that guide allows fairly precise cutting to an exact depth.   The manual give enough information – would have saved me some time .
