Ask a Question
Slitting saws are circular cutting tools designed for precise slotting, grooving and part-off operations, typically mounted on arbors to ensure stable and accurate cutting. The arbor secures the saw on the machine spindle, providing the rigidity and concentricity required for clean cuts, consistent performance and reliable tool life.
HSS slitting saws are commonly used for general-purpose machining and softer materials, offering a cost-effective solution for lower cutting speeds.
Solid carbide slitting saws are designed for higher performance, providing increased wear resistance, longer tool life and improved results when machining harder materials or running at higher speeds.
Fine-pitch slitting saws feature a higher tooth count, producing smoother surface finishes and improved control when cutting thin sections or harder materials.
Coarse-pitch slitting saws have fewer teeth, allowing better chip evacuation and more efficient cutting in softer materials or deeper slots.
To achieve accurate and stable cutting, the slitting saw bore must match the arbor diameter exactly. Using the correct bore size ensures concentric running, reduces run-out and prevents vibration during cutting. The arbor should also provide sufficient support for the saw diameter and thickness to maintain rigidity throughout the operation.
Choosing the correct slitting saw and arbor depends on the workpiece material, required slot width and cutting depth, machine capability, and the level of accuracy or surface finish needed.
Harder materials generally require carbide slitting saws with finer pitches, while softer materials may suit HSS saws with coarser pitches.
The arbor must match the saw bore precisely and provide sufficient rigidity to minimise run-out, vibration and tool wear, ensuring safe, accurate and consistent cutting performance.
Improving slitting saw tool life starts with a stable setup and correct cutting conditions. Excessive run-out, poor machine rigidity or incorrect feeds and speeds can overload the teeth and lead to premature wear or breakage.
Ensuring proper chip evacuation and using coolant where appropriate will help control heat build-up, maintain cutting performance and extend tool life.
