Planers, Jointers & Joiners

Planers, Jointers and Joiners

Planers and jointers are the woodworking machines that prepare timber for joinery — flattening one face (jointer), bringing the opposite face parallel and to thickness (planer), and squaring edges. For cabinet shops, joinery workshops, and trade carpenters working with rough-sawn or salvaged timber, these are the machines that turn raw stock into usable material. AIMS Industrial supplies planers, jointers, and combination machines for trade woodworking and industrial timber preparation.

What each machine does

• Jointer (also called a planer in some markets) — flattens one face of a board against a flat reference surface, producing a true face for subsequent operations
• Thickness planer (also called a thicknesser) — takes a board with one flat face and brings the opposite face parallel and to specified thickness
• Combination jointer-thicknesser — single machine that performs both functions, common in trade and small-shop workshops
• Joiner / biscuit joiner / domino joiner — small portable tools that cut joint slots for biscuit or domino joinery

Trade and commercial use

The planers and jointers in our range are positioned for trade and commercial use — heavier-duty motors, longer infeed and outfeed tables, and replaceable wear parts. Hobby-grade machines from big-box retailers may look similar in basic specifications but have shorter warranties on commercial use, smaller cutting capacity, and limited parts availability. For trade users, the difference shows up after months of regular work.

Sizing — the key spec

Planers and jointers are sized by maximum board width — a 12-inch jointer handles boards up to 12 inches wide, a 15-inch planer handles boards up to 15 inches in thickness pass. For the work most trade joiners do (boards 200-300mm wide), 8 to 12 inch capacity covers the everyday range. Larger capacity (16-20 inch industrial machines) suits dedicated production work.

Cutterhead types

• Straight knife cutterheads — traditional construction with HSS knives running across the cutterhead, easy to sharpen and replace
• Spiral cutterheads — rows of small carbide inserts that produce a quieter, smoother finish; longer service intervals
• Helical cutterheads — similar to spiral but with helical insert pattern for further-improved finish and tear-out resistance

For workshops doing significant timber processing, the upgrade from straight-knife to spiral or helical cutterhead is a meaningful improvement in surface quality and tool life — worth investigating when specifying a new machine.

Working safely

Planers and jointers operate at high spindle speeds with exposed cutterheads — they're among the most dangerous woodworking machines in any workshop. Use the supplied guards, push blocks for hand safety on the jointer, and never reach across or behind running cutterheads. Keep the work piece in firm contact with the table; lifting mid-pass is the most common cause of serious kickback injuries.
