Chedra Design 1/16" Side-Cutting Bit for Slot Work

[Spillproof]

I tried a few methods and the most successful was to mount the Dremel pointing straight down at the ground and have the work area VERY well lit. It's very fast, and the learning curve is steep, but it's way better than starting the slot with a Kemper saw imo. There will still be plenty of needle file/SP work to make it pretty but this will definitely save time.


ETA: sorry the photo angles are weird. I was holding my phone between my knees lol.

The learning curve is STEEP for me with it.

Yep anyone using this WILL screw up the first several efforts. I don't recommend this for people who want to fix A stem. But I do for pipemakers who have to think about time:money.

I have one of these. I ruined one stem, and swore it off. I’m a control freak. Maybe I’ll give it another go at some point.

I start my funnel with a kemper, but I made this to make quicker work of it.

Yep I've used a modified blade like that as well. Easier to control the direction than it is with a Kemper for sure.

Pipe-shiv. LOL. Course some of us don't need to park a truck in the airway, so we prefer smaller tools.

I had a similar burr-like cutter that George suggested and it worked great. Slow RPM was the key - then you could use a wee bit of leverage. At higher speeds it was more likely to grab.

I use a Foredom with a foot cotrol.
I’ve found that in addition to slower revs, running the bit only in the outward direction keeps me in the same plane.
I insert the bit while it is not turning or barely turning, then cut only as I withdraw. This allows me to avoid cutting false channels off plane.
Additionally slow revs are an absolute must when working with acrylic-otherwise the acrylic melts ands its a disaster.
