Austsaw MC1031620 103mm x 20T 4mm Milling Cutter Blade

The Austsaw 4mm Milling Cutter Blade is a carbide tipped blade for angle grinders, listed by Austsaw for aluminium tanks and boat repairs (manufacturer-stated). Three sizes are listed: 103mm (4"), 115mm (4-1/2") and 125mm (5").

All three sizes have a 4.0mm kerf with a 2.8mm plate, a -5° hook angle and a maximum speed of 15,000 RPM (manufacturer-stated). The 103mm blade has 20 teeth and a 16mm bore; the 115mm and 125mm blades have 24 teeth and a 22.2mm bore. Austsaw describes a triple chip tooth grind, with trapezoidal tips listed in the catalogue table, a hardened tempered body with carbide tips, and says the blade can be resharpened.

The maker states that the blade must be used with an additional guard on the angle grinder and recommends the Austsaw Spark Buster angle grinder guard. The catalogue page also notes that lubricant must be used when cutting aluminium, and lists Aly-Lube aluminium lubricant (manufacturer-stated).
