## Questions & Answers

**Q: Anybody having issues with slipping? I am just wondering why the round shank and not hex or at least no-slip?**
A: I've had them a while now. Drilled both wood and steel with them and they're still sharp. It's never slipped for me, however I think the issue of slipping is more related to the quality of your drill. So if your drill has a solid chuck it will be just fine.

**Q: How do these handle stainless steel? Will they old up or am I better off just buying disposable Harbor freight?**
A: Stainless is tough metal, you need carbide or maybe a cobalt.
It is expensive to tool, and expensive to buy.

**Q: where is this made?**
A: Thank you for contacting Irwin Tools.  The country of origin for this set is China.

**Q: Is this a two step process compared to something like the snappy quick-change 5-pc set which is an all-one process?**
A: Yes. - Different type product, it's 2 steps.1) Drill a hole, then 2) you can come back with this and countersink a spot for the screw head.I've got a similar one, but not Irwin, so I won't comment on quality, but the style seems to work fine.  I did notice you can make it "wander" a bit, so if you are trying to line up holes, the other style might be a better choice.

### ⭐⭐⭐⭐⭐ Great for deburring new holes or countersinking holes for bugle style fasteners “where appropriate”.
*by F***E on January 3, 2026*

Have had these for a while now and have served their purpose well. Although i have no idea why one individual destroyed the efficacy of their cam retainer plate for counter sunk screws. Lmao as his camshaft ejects itself from the block, as counter sunk fasteners are NOT stronger than conventionally headed bolts. After much use are still just as sharp as the day they arrived, although i ALWAYS use a cutting/tapping lube. Overall have had great results with Irwin products. Cheers
