No more pilot holes needed
The self-centering tip is a game changer. I was able to drill precise holes in thick alloy without needing to pre-drill. Highly recommend for DIY furniture repair.

Perfect for my workshop projects
This drill bit cut through stainless steel sheets like butter. The serrated edge really helps prevent slipping when starting the hole.

Good for thin to medium metal
Works excellent on sheet metal and standard aluminum profiles. Struggled a bit with very thick industrial steel, but that is expected for this size.

Essential tool for metalworking
Bought this to modify some garden furniture frames. The step design allows me to get the exact hole diameter I need without changing bits. Very satisfied.

Stays sharp after heavy use
I have drilled over 50 holes in various metal brackets and the bit still looks brand new. The gold coating seems to reduce friction effectively.

Great quality, slightly pricey
The cobalt construction feels very solid. I used it to expand holes in a metal cabinet frame and it worked flawlessly. Just wish it came in a set of different sizes.
Q: How do I clean the bit after use?
A: Simply wipe off any metal shavings with a dry cloth. If resin or heavy residue builds up, you can use a mild solvent, but avoid abrasive cleaners that might damage the coating.
Q: Is the shank compatible with impact drivers?
A: Yes, the round straight shank fits standard chuck drills and most impact drivers, though we recommend using a standard drill for better control on precision holes.
Q: Can this drill bit be used on wood?
A: While primarily designed for metal, it can cut through wood. However, for best results and longevity, we recommend using it on metal, plastic, or thin alloy sheets as intended.
Q: What is the maximum thickness of metal this can drill?
A: This specific bit is optimized for sheet metal and plates up to 4mm thick. For thicker materials, please ensure you use a low speed and steady pressure.
Q: Does this come with lubricant?
A: The package includes the drill bit and a storage case. Lubricant is not included, but we strongly suggest using cutting oil when drilling stainless steel for optimal performance.
