【 Warm Reminder 】 When purchasing drill bits, do not only compare prices. Comparing prices alone can easily lead to being deceived. There are numerous grades of drill bit materials. Many dealers will pretend to be of inferior materials, and in some cases, the dealers' prices may even be lower than those of the manufacturers. Since our drill bits are produced by ourselves and the profit margin does not exceed 10%, the cost performance is definitely guaranteed. With the same quality, you may not be able to find a lower price. Recently, some merchants have been passing off ultra-low-priced drill bits as 4341 or 9341. After random sampling tests, the quality is not satisfactory. The actual material is 4241 (the raw material cost is half that of 4341). Please pay attention and welcome to compare.
