The 1/4 inch hex shank makes them ideal for quick changes, especially when working between multiple tools or jobs. I’ve bought the set twice now so I can keep a set in different toolboxes, and so far, no signs of them going dull.They cut cleanly and consistently, and for the price, they’re well worth having on hand. Solid bit of kit for general use. ### ⭐⭐⭐⭐ Lovely countersink bits! *by on Reviewed in the United Kingdom 1 August 2024* Nice short length and easy to fit and remove from my drill.I've not used these extensively but from the few times I've used them the produce a nice clean cut. ### ⭐⭐⭐⭐⭐ Excellent tools *by on Reviewed in the United Kingdom 14 October 2025* Excellent price, excellent quality.
