Timber Cutting Saw Blade
Processing structural timber and raw logs demands cutting consumables built for sustained mechanical stress. Sipu engineers timber-cutting bandsaw blades specifically for heavy-duty sawmill environments and primary wood breakdown operations. By utilizing premium alloy steel paired with induction-hardened tooth tips, our blades deliver clean, straight kerfs while minimizing deviation through dense heartwood and knotty sections. Whether running continuous shifts in an industrial timber yard or handling custom dimensional lumber milling, operators rely on these blades for predictable output and reduced downtime.
Product Specifications
|
Technical Parameter |
Factory Metric & Build Standard |
Workshop Operation & Selection Guide |
|
Band Width |
35mm / 38mm / 50mm / 75mm / 100mm |
Select broader profiles for high-horsepower carriage setups to eliminate blade flutter in massive logs. |
|
Plate Thickness |
0.85mm to 1.10mm |
Use thinner gauges to minimize sawdust kerf waste on valuable timber; heavier gauges resist high-feed tension stress. |
|
Tooth Pitch |
19mm, 22mm, 25mm spacing |
Apply 25mm spacing for high-moisture green logs to prevent chip packing and gullet clogging. |
|
Rake Angle |
9° to 12° positive angle |
Provides aggressive bite force to pull smoothly through dense, fibrous grain structures. |
|
Base Steel |
European high-carbon spring alloy |
Offers extreme tensile elasticity to withstand continuous thermal expansion and flywheel shock. |
|
Edge Hardness |
59–62 HRC induction-hardened |
Maintains sharp tooth points through abrasive bark and hard knots while keeping the core flexible. |
|
Weld Joint |
Electron-beam butt-welded |
Precision-ground flush with the blade body to prevent bumps and ensure silent, stable pulley tracking. |
Custom Manufacturing
Every timber processing facility operates under unique parameters. Beyond standard stock sizes, we offer direct factory customization covering custom lengths, specialized tooth angles, and bulk loop welding. Procurement teams and global distributors benefit from consistent batch quality, competitive volume pricing, and dependable export packaging designed to protect blades during long-distance transit.

Primary Application Fields
Designed to perform across multiple stages of the timber supply chain, these blades excel in:
Log Breakdown & Primary Sawing: Splitting large round logs into cants and flitches with minimal kerf waste.
Dimensional Lumber Production: Ripping softwoods and hardwoods down to precise structural building sizes.
Green and Seasoned Wood Processing: Handling high-moisture green timber without gumming up or losing tension control.
Sipu sawing products are sold both domestically and internationally
FAQ
Q: How do I choose the correct tooth pitch for cutting dense hardwood logs?
A: Selecting the right pitch prevents stalling and excessive heat generation. For hard or high-density timber species (such as oak, maple, or dense exotic logs), choose a wider tooth spacing (e.g., 22mm to 25mm pitch). This gives larger wood chips enough room to clear out of the cut zone before the next tooth enters, avoiding binding and blade waviness.
Q: What causes a timber cutting bandsaw blade to drift or wander in the cut?
A: Blade drift typically stems from incorrect blade tension, dull tooth tips, or improper guide bearing alignment. If tension is too low, the blade will flex under heavy feed pressure. Check your machine tension gauge, ensure the teeth are uniformly set, and clean any accumulated resin off the blade body.
Q: Can these blades handle both green timber and kiln-dried lumber?
A: Yes. However, green wood contains high moisture and resin, which creates more drag and friction. For continuous green timber milling, use a blade with a slightly deeper gullet and lower feed speed to prevent sawdust packing. For dry lumber, standard tooth geometries will deliver clean, smooth finish cuts.
Q: Do you support custom lengths and welded loops for specific sawmill models?
A: We supply custom-welded bandsaw loops tailored to any vertical or horizontal sawmill brand on the market. Simply provide your exact blade length, width, thickness, and preferred tooth profile, and our factory will produce ready-to-run loops matching your equipment specs.
