Fisch 16mm engineers countersinkI bought this countersink as I new i would be wanting to countersink some holes in some 3mm mild steel, for No 10 wood screws. After countersinking 16 holes, using a lubricant, the cutting edge of the countersink was worn and refused to cut any more metal. The part of the countersink that started to cut the sharp corner of each hole ended up with a groove in it. The angle of the cutter seamed to be good in as much as it did match the angle on the screws. Not good value for money, am very disappointed . Definitely not like some of Fisch drills I have purchased in the past..I have had to resort back to HSS drills..
