3pcs 1/4 Inch Hex Shank 5 Flute 90 Degree Chamfering Countersink Drill Bit Set 12mm 16mm 19mm

Really pleased with these countersink bits. 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.

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 price, excellent quality. These countersinks are very useful tools

Good quality Perfect size. Do the job

Very sharp,very accurate and gave a clean cut. Left the counter bore free from tearing and provided clean surface to apply plug and glue

I cannot complain for the price. The edges are not the sharpest but what do I expect for something of this price. I needed something to fit my battery screwdriver with a hex drive to just take the edges of my 3D printed holes and chamfers. I tried it and all 3 work. Can't say anymore.

Very good

Sharp, good price
