70302-12 12 Oz. Soft Blue Paste Machining Lubricant

I use this exclusively when drilling or tapping and it always works great!

I tried it since drilling some 316 cres. Broke 2 colbolt bits. Tried again with this stuff, same speed and feed, rubbed bit in the lube and worked, smoother to and felt cutter better on the mill. Should have used it prior and save me breaking two bits. I would recommend it. Still you look and think nah..

I use this to machine aluminum, copper, brass, bronze and magnesium so far. Soon I'll be using it on mild and stainless steel, titanium and inconel. Helps with finish, temps, chip evac and tool life. The photo is of a project I'm doing with magnesium AZ31, the finish is silky smooth and the pattern is beautiful. I surfaced and left .002" behind to finish/pattern. Smeared a thin coat about the size of half an M&M along the top, ran a quick operation at .002" depth and now she shines...you can see some of the Boelube left in the hole that was milled out prior to facing. HIGHLY recommend this to any machinist who doesn't like or utilize flood coolant systems. Super easy to work with and easy to clean up. Remember to keep it cool as it starts to liquify once you start hitting the 80-85 degree F range. I've also used it with HDPE, UHMW, PVC and cast acrylic, works very well there to to keep heat down and provide a silky surface finish.

The best thing I have found for drilling. Dip your drill bit in it and it will make the drill bit cut 100 times better than anything else and makes drill bit last 10 times longer.

This is the best lube for tapping!

Dramatically helps drilling and cutting. Allows you to drill holes like its a brand new bit on every hole. I also dab a little on my metal band saw and it cuts way better and makes my blades last much longer. a little goes a long way, and i mean a little. It does start to liquefy above 100deg. I leave it inside since i live in Arizona and the garage is well over 100deg for months at a time.

100% top recommendation for when you need to drill out a hardened steel bolt with a hand drill. Stuff works better than any other cutting lubricant I have seen. I’m glad I listened to a co-worker and nabbed it. This stuff is a life saver.

it does help with keeping them lasting longer!!
