Beam Saw & Panel Sizing Blades

Beam saws — also called horizontal panel saws or panel sizing saws — cut stacks of sheet goods to finished size in a single pass. They never run one blade alone: a large main sizing blade makes the cut while a smaller scoring blade runs just ahead of it, pre-cutting the underside of the panel so melamine, laminate, and veneer break out clean instead of chipping. That pairing is the whole job of the machine — and it's how this collection is built.

Every sizing blade has a matched scoring blade

On a beam saw the main blade and the scorer only work as a set. The scoring blade's kerf has to be matched to the main blade's kerf, and its diameter, bore, and projection have to suit your saw's scoring spindle. Get that pairing right and the top face of the panel is fully supported and chip-free; get it wrong and you'll chase chip-out no matter how good the main blade is.

So for every main sizing blade we stock, there is a specific scoring blade that is its correct partner — a true 1:1 match, not a "close enough" substitute. Tell us your machine, or the main blade you run, and we'll give you the exact matched scorer. No guessing on kerf, no mismatched projection, no wasted panels.

The recommended choice: LORNA Industrial

Every blade here is built for production beam saws, and our German-made LORNA Industrial line is the one we put first. LORNA plates are precision-ground from high-grade tool steel and tensioned for stability at production feed rates, then tipped with fine-grain micrograin carbide that holds a sharp edge far longer between sharpenings. The triple-chip (TCG) grind on the sizing blades is purpose-made for melamine, MDF, particleboard, and double-sided laminate — it shears the brittle surface instead of tearing it.

LORNA HPS main sizing blades and LORNA CSA scoring blades are ground to original bore, pin-hole, and projection specs, so the pair drops straight into your saw. Because they hold their edge and resharpen well, the number that actually matters — cost per cut — comes out lower than a cheap blade that dulls fast and chips panels.

The value alternate: Popular Tools

When you want a proven workhorse at a lower entry price, our Popular Tools line (made in Taiwan) covers the same sizes. PS and NPS main sizing blades pair with SC scoring blades for a complete set at a sharper price — a smart pick when the budget is tighter or you're stocking a spare.

A note on NPS: the NPS series is its own line of sizing blades, with its own diameters, bores, and tooth specs — it is not a substitute for a PS blade. If your machine runs an NPS-series blade, order it by its NPS number; it's a distinct item with its own matched scorer. (Searching an NPS part number? You'll find the exact NPS blade here, not just the nearest PS.)

Made to fit the leading beam saws

Our sizing and scoring sets are made to fit the machines that run the cabinet, casework, and furniture shop floor, including:

• Holzma (HPP, HPL series)
• Schelling (fh, fk series)
• Giben (Prisma, G series)
• SCM / Gabbiani (Sigma, Galaxy)
• Biesse / Selco
• Homag
• Cantek and other production panel-sizing machines

Main sizing blades run common beam-saw bores from 30mm up to 75mm with the matching drive-pin patterns; scoring blades cover the conical and two-piece adjustable styles these saws use. Not sure of your bore, pin pattern, or scoring kerf? Our blade finder or a quick call will land you on the right pair.

How to choose the set

• Main sizing blade — match diameter, bore, tooth count, and pin-hole pattern to your saw. A high tooth count with a TCG grind gives the cleanest cut in coated panels and MDF; a lower count clears chips faster in thick stacks of raw board.
• Matched scoring blade — choose a one-piece conical scorer or an adjustable two-piece split scorer, sized so the scoring kerf sits just wider than the main blade's kerf. Need adjustable split scorers specifically? See our split scoring sets.

Built to be resharpened

These are industrial blades meant to earn their keep over thousands of cuts. The carbide is generous enough to be resharpened repeatedly, keeping cost per cut low across the life of the blade. (Sharpening is arranged through our service partners — ask and we'll route it.)
