Accusize Industrial Tools 5pc ANSI M42 (H.S.S. + 8% Cobalt) Center Drill Set, 0556-5500

Backup set. Always wonder where they go to hide or if "little fingers" dissapear them. Good price and they work well. Doesn't take much lost time to pay for "spares".

Worked well on pre hardened stainless steel, after drilling a dozen or so holes still felt sharp. hopefully will hold up over time.

I am used to using far higher priced center drills, at work. Since these are for my personal use (on stainless steel), I went with a lower price (but they have worked fine). So far, so good.

These work fantastic, I've done stainless steel, mild and many soft metals, These cut them all like butter.I'm seeing a lot of reviews about brittleness? I think the people who break this tool are feeding it into the material way too quickly, these cut fast and deep, take too big of a cut/ fast of a feed speed and they're gonna catch on too big of a piece of material and snap. But that's how good these are, they cut every thing super easily. You have to feed it into the material at a somewhat slow pace, doesn't have to be snail pace, just don't JAM them in there and magically expect a hole.

Good product, good price.

Very handy set to have in the shop, great for tight spots.

Using these for broken off bolt extraction.

I still buy these because they are cheap but they break frequently. The cheap price outweighs the inconvenience in my shop.
