Imperial M35 5% Cobalt Drill Bits Set (1/16-1/2 Inch,17PCS) for Hard Metal and Stainless Steel

I was half way through a project and found that none of my "normal" drill bits were capable of drilling through the stainless steel bars I was using - so, in desperation, I bought these despite doubting that they'd actually be any different. How wrong I was... if you follow the instructions they give you (don't let the bit tip overheat; use some form of cutting fluid; keep the rpm low), these really do let you drill through very tough stainless steel. Used the same bit for 6 holes and it still feels sharp. BTW, I didn't have any 'proper' cutting fluid so I just used a light oil - not sure if that's right but it seemed to do the job.

Prompt delivery, robust container, excellent verity of drill bits

Excellent quality nice case keeping drills organised

very good

Excelentes para perforar acero inoxidable, al hacerlo hazlo a baja velocidad, lubricando constantemente y con cuidado. Son muy afiladas y de buen material

This is by far, the very best and highest quality drill bit set I have ever owned. Unlike other bits I have encountered, these bits stay sharp and get the job done. They are ideal for drilling through steel and iron plates leaving sharp, clean holes every time. The warranty is also great - break a bit and they will replace it free of charge. Warranty card is inside drill box. While I'm praising the bits, let me also acknowledge that the drill bit storage box is really nice too. Yes, it's plastic, but the quality stands out from other brands as well. The bit clamps actually "hold" the bits tightly in place while stored, and the closure mechanism is top of the line too. I am NOT a paid reviewer or someone who got the product so I would review it. These are my actual assessments of this product. I just felt strongly enough about it to let others know what a great product it is and give STROTON their deserved credit.

Bon pour le prix

These are fantastic drill bits, worked first time out, cut through stainless steel like a hot knife through butter, DeWalt's didn't work, returned them, another brand that Amazon sold also did nothing, these are without a doubt worth it. If you need a strong, sharp and winner, but them.
