These ones made my life so much easier and saved me a lot of time. Always use a bit of cutting oil/spray when drilling metal and these are still sharp after use and hardly a scratch on them. ## Frequently Bought Together - BOSCH CO14B 14-Piece Assorted Set with Included Case - Cobalt M42 Metal Drill Bits with Three-Flat Shank for Drilling Applications in Stainless Steel, Cast Iron, Titanium, and Light-Gauge Metal - Tap Magic 30004P ProTap Cutting Fluid, 4 oz.
