HOZLY Titanium Nitride Coated Carbide Review

Based on our own experience, we cannot recommend this product for industrial and scientific purposes. The bits did not provide precise CUTS and required frequent replacements. The only positive aspect is the titanium nitride coating, which prolongs the life of the bits.However this does not compensate for the lack of quality. We were hesitant buyers, and unfortunately, the product did not meet our expectations..

The HOZLY drill bits are not the best choice for any industrial work. My analysis of this product showed that its titanium nitride coating claims are not to be trusted. The coating chips off easily reducing the bit`s performance and leading to the increased possibility of breakages. The only positive feature of this product is the low price, but that hardly compensates for the frustrating experience of working with substandard equipment..

Use on poplar wood (hardness 540) with the same settings as bits from other brands. The first broke on contact with wood during installation. The second worked fine at first, but broke an hour later on a straight cut. I have HOZLY 1.5mm bits.
