Bosch2608596667 3 PCE Countersink Bit Set 50 Mm .6-8 Mm .8-10-12 Mm

Usual great Bosch quality. Did the job perfectly. Good sizes for a variety of jobs. Used on MDF skirting.

Ok not the sharpest of bits but get the job done

I may have misunderstood the purpose for this tool but it is hopeless with hardwoods.

Cannot recommend these at all, on first use the cutter failed completely. See attached picture for the results of first use (including an unused bit for comparison).Used in a drill press, so not a result of wobble, just poor choice of material by the manufacturer.Probably OK for Aluminium and plastics but on steel a waste of time, keeping the other two for use on wood/plastic only.Hoping this will fare better:  PROJAHN 701066060 tungsten carbide rotary burr countersink 90° , shape K d1 6.0 mm, shank 6.0 mm cut 6 double cut

Perfect

Good

Shocking for a supposed genuine Bosch product. Wouldn't countersink any material.returned for refund
