Review on Uxcell 0 3Mm 1 2Mm Tungsten Carbide Engraving Cutting Tools by William Dean

This review is about Uxcell Tungsten Carbide Circuit Board Drill Bits in 0.3-1.2mm in 0.1mm increments. I've found drill bits to be very effective when drilling post-processing holes for PCBs. I haven't had any breakage issues despite using a small Dremel drill stand, which is essential when using a small drill of this type regardless of brand. I've used the 0.3mm drill bit several times without breaking. It is important to ensure the safety of your work, work slowly and clean the hole from time to time, and then continue drilling. I also use them for drilling PCB vias when I need to separate a small area's ground from ground. As a reminder, drills of this size cannot withstand the side load of the drill, so using a drill stand with them is important. I'm sure if you do, you'll live a long life with these pieces, as will I.
