M42 Cobalt Steel Square Lathe Tool Bits - 1/2 X 1/2 X 4 Inch - Fly Cutter Blanks (Single)

Hey machinists!

Need some serious cutting tools?

These are M42 cobalt steel square lathe tool bits.

They measure 1/2 inch by 1/2 inch by 4 inches long.

M42 cobalt is a step above regular HSS—it holds an edge better at higher temperatures, so it's great for tougher materials.

They're blanks, so you grind them to the shape you need.

Perfect for lathe work, milling, or fly cutters.

They're brand new, unbranded, but the material is legit.

California Prop 65 warning applies, but that's standard for industrial tools.

Stock up your toolbox with these tough bits.
