Before starting any DIYs which includes drilling, cutting blades, milling and more, be sure to spray a few coats of WD-40 Specialist® Cutting Oil onto the tool surface (i.e drill bit or saw blade).
2.
Let the formula sit for a few seconds, then you can proceed to drill or cut like normal with the residue left on it.
3.
Wipe away any excess or leftover residue before starting over. You can now officially improve machine finishes and extend tool life!
