Hi,

My name is Boyan. Maybe you happen to know me from some CNC forums where i am an active member. I do tons of woodwork on my custom DIY CNC. So i know a lot about dust and dust extraction, especially about the home and small workshop scenario.

I have used various commercial and DIY solutions for Dust Shoe / Boot/ the last years. Unfortunately most of them had some minor or bigger flaws, which made them unusable with the time. So i decided to develop some simple and working dust shoe for my machine, that will cover the typical scenario.

A word of forewarning: On many product videos where they try to sell you a product, you will see how the dust shoes perfectly suck the dust and and not even a single chip is left on the table. Unfortunately in real life there is almost not such situation. On product videos dust boots are connected to powerful industrial "suckers" and 100% showing you the best scenario where a sheet is cut. So the dust boot traps 99% of dust and chips.

However what i typically do at my workshop is exactly the opposite. I cut out a shape from a wood block which is raised on a vacuum fixture, so it could be said that this is the worst case scenario. As chips and dust try to escape from the clearance between table and work block. Hence when i designed the dust shoe i had always in mind worst case scenarios, not ideal situations from product videos

What i offer here to your attention is an Universal Dust Shoe/ Boot/ which i call the Turbo Dust Shoe.

Good for High and Low pressure vacuum cleaners and chip extractors

-Designed for excellent flow. Big chips have excellent passage and will not get stuck inside the body.

-Hi volume Low pressure chip extractors in the 100mm hose range will not choke and loose power.

-Hi pressure workshop vacuum cleaners will work excellently with it. Even a small home vacuum cleaner will be enough to suck 100% of the fine dust and most of the chips.

-Best extractor for the job will be a typical brand shop vac with 2 stage minimum, even better 3 stage motor in the 40-60mm hose range. Where Hi Volume High pressure is achieved.

On the images you can appreciate 3mm bit, 6mm bit and 12mm bit. The red Brush attachment is just so long as to clear even the smallest bits used. Obviously a brush is not needed with the short bits.
