Delivery time to Serbia 3,5 weeks.Well packed and good quality. I tested 18,5 mm drill on hard wood and mild steel. I was able to drill trough 20 mm wood by removing inside plug with screwdriver after every 5 mm of cut depth. Final hole diameter was 18,6 mm. Cuts trough 4 mm mild steel with no problem. Final hole diameter was 18,8 mm. Always use cutting oil and right (slow) speed for steel cutting to save sharp edges. Produce long shavings during cutting. After some steel cutting is it still sharp as new. Inside waste part left after steel cutting can be used as small circular knife.

с виду неплохие, а качество неприятно удивило. для метала непригодны, при сверлении на малых оборотах шуруповёртом с маслом тоненького металла меньше 0.5 мм постирались после 10ти отверстий. тут же покупал другие коронки поштучно, красного цвета - те повыносливей
