Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

Outstanding lubricant for light machining applications.This product works wonders with basically anything involving machining something by hand that needs lubricant. I have used it many times for lubricating taps when cutting and chasing threads, as well as when drilling the initial holes or any time I am drilling through metals. It cools effectively and helps clean any shavings out to prevent bits and taps jamming. The metal container it comes in has a small opening so the oil is easy to control and distribute in small amounts. The sheetmetal construction lets you squeeze the container so only a few drops come out at a time. When using with a Tap: drip some of the oil onto the threads of the tap before inserting into the pilot hole. Make sure to back the tap out occasionally to clear the threads of fresh cut metal shavings or the tap can jam and destroy the freshly cut threads. When using as a Drill lubricant: I always drill metals on the high torque, low speed settings on my hand drill or drill press. I use this oil as a mild coolant in this case as well as a lubricant. I have not tested its maximum cooling capabilities or what its smoke point it, but on both my hand drill and drill press I have never had an issue running at the recommended speeds for steel, aluminum, and various other iron and aluminum alloys. My reference for drill bit RPM is the Irwin Metal Drilling Reference Guide: [...] I have nothing bad to say about this cutting fluid.

good

I wish I could just leave a 5-Star review and thats it.

Absolute must if youre using a tap kit. It makes cutting so much easier and increases the longevity if your taps by reducing the friction and force necessary to cut something.

Worked well for project i needed it for.

I do a lot of drilling of thick steel, and this helps keep your drill bits from burning up. Ive used this stuff for years. Also great for cutting threads on steel rod.

good cutting oil

Works as advertised.

I have used plenty of this Tap Magic cutting fluid and it works great. I will buy again
