amoolo 1/4" Cobalt Drill Bit (10 Pcs), M35 HSS Metal Drill Bits Set for Hard Metal, Stainless Steel, Cast Iron Box of 10

Bits work great and at a great price

Great drill bits at a good price! I have gotten a lot of "mileage" out of each bit before dulling. Very satisfied with this brand.

I tried 5 different Cobalt bits. Ordered from 3 different companies. They weren't sharp. Sent them back. Took a chance and ordered from a 4th company with good reviews for sharpness. A gain the bits were not sharp. Dent them back. Thought I would give it one more fifth try from this company. HURRAH !! Opened the package , took a bit out and tried it. IT DRILLED THE HOLE IN MILD STEEL ALMOST LIKE BUTTER. THEN DRILLED 2 MORE HOLES WITH THE SAME BIT. NO PROBLEMS DRILLED THEM EASILY. WOULD DEFINATELY RECOMEND THESE BITS. ARRIVED IN ONE DAY. VERY SATISFIED.

Just drill bits. Nothing special.

The Amoolo 1/4" Cobalt Drill Bits are sharp and cut through metal, wood, and plastic with ease. They don’t overheat quickly, and the precision is great. The value for a 10-pack is solid. However, I noticed they wear out faster than expected when drilling through harder metals. For light to medium-duty work, they’re excellent, but for heavy use, they might not last as long. Overall, a good buy for the price!

Impressed by these drill bits. Purchased for drilling ¼" holes for tension cable railing. Drilled 84 holes through ⅛" think galvanized steel tube with a single bit. Still have 9 x bits left brand new, and the first one is still good.

I leave very few reviews, yet want all to know these are excellent quality, sharp bits that work exceedingly well for my use in drilling starter holes in stainless steel. Use 1/4" bits of the same brand to make my final hole.

There not the best drill bits for drilling wood deck down to steel, they are only good for 2 to 3 holes

I bought these drill bits in 1/8 1/4 and 6.5mm for drilling out stainless steel rivets. They worked very well. Drill at slow speed for best results on SS. The 1/8 size, extra care is needed as they are small and break if to much pressure is used Never broke any of the larger sizes

This doesn't work as expected. Too high price

Excelente brocas para metal duro y diferentes tamaños para el uso de trabajo.

Très bonne mèches pour percer le stainless. Très bon prix pour la qualité.

Can't say much about these bits, I expected to blast through the pack as I had at least 400 holes to drill but I only needed just one bit.
