Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

o.k.

I burned out several bits on two 1/2 inch hardened bolts and bits barely made a mark. I saw this product while looking for a solution and bought it. What a difference was able to drill them both out easily. I was surprised at the difference this product made.

Used to drill 336 holes in ⅛ wall pole and this oil is magic. The cheap hole saw bit I used was still going strong at the end.

Good stuff

Works as advertised on aluminum.

It worked as expected.

Great product holds up well does what it said it would.

This is extremely helpful for drilling and tapping 3mm holes. It is amazing how much easier it is when using this...

Amazingly effective

Works as intended a good cutting oil
