Infinity Tools DIY Dust Separator Lid Stiffener

It's a precision CNC-milled 1/2" thick MDF stiffener (part 115-278) that reinforces the lid of a five-gallon bucket. See more dust collection gear.

It strengthens a five-gallon bucket lid so it can serve as a robust mounting location for a first-stage dust separator, keeping the separator stable and in use for a long time.

It's designed to pair with the Infinity 115-279 dust separator mounted on your own five-gallon bucket for a cost-effective first-stage setup.

Attach the stiffener to your bucket lid and cut out the center hole. That gives you a robust mounting spot for the separator — simple and cost-effective.

Many first-stage separators use expensive components that make them costly for what they are. Pairing this stiffener and the 115-279 separator with a bucket you already own is a much more affordable solution.

No. The stiffener is designed to pair with your own five-gallon bucket, which keeps the overall cost down. You'll also want dust collection fittings to connect it.

It's made by Infinity Cutting Tools and carries part number 115-278. Explore more dust collection products.

It's 1/2" thick CNC-milled MDF, giving the bucket lid enough rigidity to support the separator securely.

Yes. By providing a robust mounting location, the stiffener helps keep the separator in stable use for a long time to come instead of flexing or failing at the lid.
