    Remekül teljesítettek, egy acél I gerendán lett kipróbálva. Semmi hűtés, semmi spray. Csak maga a fúró. Éle nem ment ki és gyönyörű egyenletes forgácsolással ette magát előre. "Táncolást" nem tapasztaltam használat alatt

    I stress tested these last night in a 1.5 HP lathe with no coolant. I ran the drill bits in 2mm increments in the lathe tailstock and fed them into a nasty piece of 316 austenitic stainless steel. They performed flawlessly until I plunged the 10.5 mm in at 600 RPM with no coolant, whereupon the cutting edge dulled. I reground it successfully. I ran the remaining drills at 350-200 RPM with no coolant and they all cut perfectly. This is astonishing for the price. To celebrate I started making a drill index in 20 mm 6061 aluminium.

    As others have mentioned the grind quality is very good if not excellent. I think the official photos on the Banggood listing may be old stock as the set I received actually looks much beater than the official photos. Ill try to upload a closeup of the set I received. So far I have used a few of these in both mild and high grade frame steel and the performed very well. on par with my fractional inch set of Milwaukee cobalt bits which cost way more for about half as many bits. Note they do not come with a case. however if you have a 3d printer, I designed one specifically for this set and posted the files on thingverse; thing # 4251707

    Very good quality but not so good sale service and worse aftersale support. My 25 pieces drill bit set was delivered missing 10 mm bit. Had been contacted Banggood by e-mail and all i recieved is waiting for nothing .

    Teljesen rendben van. Éles, elég jól bírta a strapát. Idáig nem tört el egy sem. Egyedül a 6.5mm-es ment tropára, az valami kemény zárványba lett beletolva. Alig lehetett kiszedni. Elsőre még az mondanám egy köszörülés és teljesen rendben is lesz.

    Набор сверл пришел довольно быстро, как раз в нем возникла необходимость. С работой самым большим сверлом справился. Судя по всему будет хорошим подспорьем в хозяйстве.

    Very sharp, durable and well made bits. Hold up well when drilling steel. Far superior to coated HSS bits.

    Доставка три недели с момента заказа. Доставлен в двойном пакете, хотя просил упаковать хотя бы в картонную коробку. Удивительно, что не рассыпалось по всему пути из Китая. Начиная с 3-х мм сверла = заточка машинная, а от 1 мм до 2,5 мм = заточки нет вообще. В деле не пробовал пока, только получил их.
