Speedline Wood AD circular saw blade – 315 mm, 28 teeth (Robert Bosch)

Speedline Wood AD circular saw blade is a purpose-made cutting tool for high-quality wood cutting on panel saws and table saws, combining carbide teeth with a hardened SK5 steel body for reliable production use

• Carbide-tipped teeth for extended tool life
• 315 mm diameter for common workshop saws
• 30 mm bore for standard arbors and adapters
• 3.2 mm kerf for accurate, stable cuts

Precision and productivity for panel and table saws

The 315 mm diameter blade with 28 teeth is configured to balance cut quality and feed rate, making it suitable for cross- and ripping operations where a clean finish and efficiency matter. The carbide-tipped teeth retain sharpness far longer than high-carbon edges alone, reducing downtime for regrinds and keeping cycle times predictable. The hardened SK5 steel body, specified as hardened (> 40 HRC), provides the required stiffness to minimise run-out and vibration, which in turn lowers noise and improves the surface quality of the workpiece. For operations that prioritise throughput and repeatable quality, this blade delivers a reliable compromise between speed and finish.

Tooth geometry explained: why 28 teeth deliver consistent cuts

The blade uses an alternate top bevel tooth layout derived from the designation WZ (Wechselzahn), which alternates bevel orientation across the cutting edge to shear fibres cleanly. This geometry reduces tear-out on veneered panels and laminates while still permitting reasonable feed rates on solid timber. The term “kerf” refers to the 3.2 mm material removed by the blade during each pass; a narrower kerf minimises waste and requires less power from the saw, whereas a slightly stiffer body is needed to maintain straight cuts at this width. For users with mixed tasks—panel cutting, shelving, and furniture components—the balance of tooth count and bevel profile provides versatility without sacrificing edge quality.

Mounting, compatibility and safe operation

A 30 mm bore matches common arbor standards; where necessary, standard bushings can adapt the blade to other spindle diameters. The blade’s SK5 steel core with carbide tips means that heat resistance during normal cutting is improved, but users should still observe correct feed speeds and avoid prolonged loaded cutting that could overheat the carbide bond. Proper clamping, correct saw blade flange diameter and verified run-out are the most effective measures to protect the blade and extend service life. While the tool is designed for wood-processing equipment, checking machine rpm and ensuring the blade is rated for the saw’s speed remains a critical safety and performance step.

Durability, economy and workshop reassurance

Investing in a carbide-tipped blade with a hardened steel body reduces total cost of ownership through fewer replacements and less frequent sharpening. The combination of carbide-tipped edges and a hardened SK5 substrate supports a predictable tool life in daily production. For suppliers and workshops seeking a dependable consumable from a recognised manufacturer, the blade offers a pragmatic mix of longevity and cut quality that helps maintain a smooth production flow while limiting unplanned interruptions.

FAQ

What saw types is this blade compatible with?
The Speedline Wood AD circular saw blade is designed primarily for panel saws and table saws with a 315 mm blade capacity and a 30 mm arbor; standard flange bushings permit use on compatible machines.

How does the 3.2 mm kerf affect cutting and power consumption?
A 3.2 mm kerf removes slightly more material than ultra-thin blades but provides greater stiffness; this reduces vibration and improves cut quality while requiring moderate motor power.

Can the blade be used on veneered boards and laminates?
Yes, the alternate top bevel tooth geometry is well suited for veneered panels and laminates, reducing tear-out and delivering a cleaner edge.

How should the blade be maintained to extend service life?
Keep the blade clean of pitch and resin, verify correct saw speeds and feed rates, check arbor run-out regularly, and replace or re-tension flange hardware when signs of wobble appear.
