Molyslip TAP PLUS Tapping Compound 450g Tin – Premium High Performance Lubricant Anti Wear Paste Maximises Tool Life – Drilling, Reaming, Tapping

Does the job

I was a bit skeptical of this at first. Having been using Ambersil for years i wasn't sre this would be an improvement, but i was wrong. This really does work better than typical cutting/tapping oil. You can feel it takes less force to cut threads, cuts smoother, etc. I generally use it for power tapping in the mill/lathe and it's great, highly recommended, a really good product.

Comes as a paste, l've used a liquid lube previously, but l find this much better ,l would buy again, but this would last me a long long time

Does what it says. Value for money.

I bought this to help to prolong my HSS metal drills as I have to do a lot of drilling of broken rusty bolts. I have noticed some improvement in the life of the drill bits. I don't know if this will work better on more expensive HSS drills. Time will tell.

Works well on mildsteel and tapping

Really good stuff
