3pcs 1/4" Hex Shank Countersink Drill Bit Set 90 Degree Flute 5 Flute | 12mm 16mm 19mm Sizes High Carbon Steel for Wood Plastic Working

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

Sharp, good price

Great product

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.

Worked well in application, use these countersinks infrequently so would prefer to rate them after having them for a few weeks to ensure they last. I've had inferior ones in the past which were not made out of high quality steel and have gone blunt after a few uses..These appear to be well made from good quality steel so I feel they will give me good service. I have only rated them 4 stars but if they do last it would have been 5. I would therefore kindly suggest including 'durability' or 'well made' into the rating features to reflect this

Good quality Perfect size. Do the job
