Received in good condition condition. Product need to rework before use due to burr.
The quality is worse than expected and I expected poor quality to start with. Inserts do not fit into hole due to burrs. Drill bits do not fit into inserts due to grooves. Drill bits tips need to be resharped from scratch, not even centered. It needs some work to fix faults before it can be useful. poor quality all around.
These are supposed to be drill bits... should just send them without sharpening at all and describe that the buy needs to sharpen on their own.
