PATIKIL 1.5mm Drill Bit, Jobber Straight Shank M2 High-Speed Steel 135° Uncoated Bright for Stainless Steel Medium Hard Metal - 2 Pack

Good for me

excelente solo pedi en este tamaño para probarlas, pedire de los otros tamaños

Qualität grundsätzlich in Ordnung, Verarbeitung wirkt solide. Leider nicht maßhaltig: Der 2,25-mm-Bohrer hat tatsächlich nur ca. 2,0 mm Durchmesser. Für präzise Arbeiten daher ungeeignet.

I recently picked up these 3.1mm jobber drill bits, and I've been thoroughly impressed. While the case they arrived in is pretty flimsy and doesn't offer much in the way of secure storage, the drill bits themselves are absolutely top-notch. From the first use in my blacksmithing workshop, these bits have proven to be incredibly sharp. They bite into stainless steel and other hard metals with surprising ease, making quick work of tasks that used to be a struggle. More importantly, they've shown remarkable durability. After several tough jobs, they're still going strong, holding their edge without any signs of dulling or chipping. For anyone working with metal, especially in a demanding environment like a smithy, these are truly perfect.

worked great, only used in aluminum but nice drills

This drill worked fine for clearance for a # 5-40 screw. I drilled 6 holes in 1/4 thick Hot Rolled steel with no problem. The drill did not over heat or dull. The chips ejected just fine . I see no problem at all with this drill. Ther hole was clean and round with no burrs or issues.
