Holes have drilled comformaly to drawing, That's very good! Howver, the holes have not been claened of sharp edge, that makes the job sloppy.
**Response from HSUSA** Please understand that if there is not a callout on the print to break sharp edges as well as specifications (depth/angle) for any chamfer deburring of threaded holes, this is not typically done. This ensures there is no interference with fasteners after the fact. If you would like this to be completed on your next order, there is typically no extra charge to do this. I hope this helps and we thank you for your order. Please let us know if we can be of any further assistance.
I use these sinks on two sides of a 1800 oz/in stepper motor that runs at a near constant duty cycle. It maintains temperature very well and does just what I want. This sink is cut well and doesn't have any burrs or sharp edges.
It's great to get what is advertised at a reasonable cost & fast delivery.
