- Cools the tool and thus extends its service life
- The slightly foamy consistency increases the dwell time at the drilling site
- The hinged spray tube allows precise dosing
WD-40 drilling and cutting oil (www.wd40.de, 400 ml spray can, just over €8) is designed to reduce wear on workpieces and tools during machining processes and reduce friction and heat build-up on metal parts. This extends the service life of cutting tools and drills, and the drilling process is gentle on the workpiece. Practical: Thanks to the 360° valve, the can can also be held upside down.
