In the process of using the HSS saw blade, the correct cutting angle can not only bring good cutting results but also improve its service life. Different material requires a different cutting angle and clearance angle. In this way, the production cost is saved, and the damage and cracking of the saw blade are greatly reduced.
We want to share you some information about the cutting angle of the HSS saw blade, and the below chart will show you as reference:
● STEEL＜500 N/mm2 Standard: γ (Cutting Angle) 18°, α (Clearance Angle) 12°
● STEEL＜800 N/mm2 Median: γ (Cutting Angle) 15°, α (Clearance Angle) 8°
● STEEL＜1200 N/mm2 High: γ (Cutting Angle) 12°, α (Clearance Angle) 6°
● STAINLESS STEEL: γ (Cutting Angle) 12°, α (Clearance Angle) 6°
● CAST IRON: γ (Cutting Angle) 12°, α (Clearance Angle) 8°
● ALUMINIUM: γ (Cutting Angle) 25°, α (Clearance Angle) 10°
● BRONZE: γ (Cutting Angle) 12°, α (Clearance Angle) 8°
● COPPER: γ (Cutting Angle) 16°, α (Clearance Angle) 18°
● BRASS: γ (Cutting Angle) 15°, α (Clearance Angle) 15°
● ZINC ALLOIES: γ (Cutting Angle) 12°, α (Clearance Angle) 8°
● INCONEL: γ (Cutting Angle) 12°, α (Clearance Angle) 8°
● TITANIUM: γ (Cutting Angle) 2°, α (Clearance Angle) 15°
