The very best lubricant for drilling and thread cutting. Expensive but worth the $$.

If you need to use a disc/belt sander (or a combination machine) to sand or grind aluminum angle, tube, rod, etc. this liquid Boelube works great. Apply it directly to the abrasive surface. It will, for the most part, eliminate build-up of aluminum onto the abrasive surface, and it still allows the abrasive to cut (bite) into the material...all while keeping the aluminum much cooler than other lubricants. This lubricant really is a superior product.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Is Boelube used as received or diluted?

This comes ready to use and does not need to be diluted.

Q: Is 70104-04-001 solely for hand tools? Should we only use 70090-L-001 for a pneumatic drill?

70104-04-001 is red in color, and 70090-L-001 is clear. That seems to be the only difference. This is designed to be used to lubricate saw blades, reamers, drill bits, etc etc while working with metal and they both could be used for lubricating drill bits or reamers powered by a pneumatic drill.
