WD-40 Specialist Cutting Oil 400ml, Metal Cutting and Drilling Fluid, Extreme Pressure Lubricant for Stainless Steel, Reduces Heat and Extends Tool Life, Smart Straw 360° Spray

Really good and helped a great deal when I was drilling out a snapped bolt. Helped keep my drill bits still looking new after the job

great lubricant specially formulated for lubricating drill bits to keep them cool and extend the drill bits life

Well impressed and the first time using this WD40 spray cutting oil and will definitely but again and recommend it.

Good product, it certainly works but like other WD40 specialist greases the spray is far too powerful. Cutting oil is only really needed on the cutting face of the bit you're using, so a few drops every so often is plenty. This can sprays everywhere, even with the quickest of bursts. Probably good if you're drilling a hole as big as your fist but a bit messy for the usual 1-12mm holes.

Made cutting 3mm stainless steal much easier were as with out was dulling drill bits before getting a hole.

Can’t fault it. Drilling 6mm mild steel and it keeps everything cool and lubricated. Helps with chip clearance.

Worked well.

Arrived really quickly and perfect for the job required for.
