Powermatic 1791786B Zero-Clearance Insert PM2000B is a replacement table saw insert made for compatible Powermatic saws including the PM2000B and PM2000BT. This is a table saw zero-clearance insert designed for cleaner, safer cuts on compatible Powermatic table saws. Model Number: 1791786B. If you do finish work, furniture parts, or any rip cuts where small offcuts can become a problem, this accessory earns its keep fast.

The whole point of a zero-clearance insert is support. Instead of a wide factory opening around the blade, this insert lets you cut an opening that matches your blade kerf. In real use, that means better backing right at the cut line, less tear-out on the bottom of the workpiece, and better control when you're running narrow stock across the table saw. It is a simple upgrade, but on clean woodworking cuts, it makes a noticeable difference.

Powermatic also designed this insert to help keep narrow cutoffs from falling into the blade opening, which can cause binding or interrupt the cut. That matters most when you're working with thin rips, trim material, or smaller parts where a standard throat opening leaves too much unsupported space. For cabinet parts and finish-grade stock, that extra support is worth having.

Jobsite convenience is built into the design with leveling set screws. Getting an insert perfectly flush matters more than people think. If it sits proud, material can catch. If it sits low, the stock can dip at the cut. The adjustable screws let you dial it in so material feeds smoothly across the tabletop without hanging up.

Fit is the big story here. This insert is made specifically for the Powermatic PM2000B and PM2000BT table saw platform. That product-specific fit matters because throat plate dimensions, mounting points, and leveling hardware are not universal across table saw brands or even across saws from the same manufacturer. If you own one of the listed compatible saws and want a purpose-built insert instead of a generic workaround, this is the right kind of accessory to buy.

Physical size is listed at 15.5 inches x 4.25 inches x 0.5 inches, with a net weight of 2 lbs. Those numbers tell you this is a full-size insert for the saw table, not a throwaway shim or temporary shop-made filler. It is meant to install as a proper accessory and give repeatable support where it counts.

This accessory makes the most sense for woodworkers, finish carpenters, cabinet installers, and serious DIY users who care about cut quality and control. If you're mostly rough-cutting framing lumber, you may not notice the benefit every day. But if your work involves visible edges, thin material, or narrow offcuts, a dedicated zero-clearance insert is one of those small upgrades that improves the way the saw behaves.

Powermatic 1791786B Zero-Clearance Insert PM2000B Is a Smart Upgrade for Cleaner Saw Work

This is the kind of table saw accessory that looks simple, but it fixes a real problem where it matters most: right at the blade.

• Who it's for: PM2000B or PM2000BT owners doing cabinetry, furniture parts, finish ripping, or any work where clean edges and small offcut control matter.
• Why it stands out: It is model-specific, gives better support near the blade, helps reduce chip-out, and adds protection against narrow cutoff pieces dropping into the opening.
• Worth knowing: This is not a universal insert. Buy it if you have the correct Powermatic saw and want a purpose-built zero-clearance setup instead of making your own plate.

• What saws does this insert fit? It is listed for Powermatic PM2000B and PM2000BT table saws.
• What does a zero-clearance insert do? It allows an opening that matches the blade kerf, which helps support the stock near the blade, reduce chip-out, and keep narrow cutoffs from dropping into the blade area.
• Can the insert be adjusted level with the saw table? Yes. The insert uses set screws to make leveling with the table surface easier.
