Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Good

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.

This is must have if you ever drill anything

Great stuff. Im just a home handy man kind of guy so this size will last a while. I drilled and tapped a hole and this made the cutting smooth and easy. I recommend this if you have been using WD40 as a cutting fluid. It works much better and helps prevent mistakes.

I am using this to thread aluminum 2020V and 2040 rails. Works like a charm!

Muy efectivo
