## Questions & Answers

**Q: The picture is 12-inch.  The part number is for 10-inch.  Which are they??**
A: I don't specifically recall, but we use 12" blades here. I definitely do not recall receiving the incorrect 10" length.

**Q: Will these blades cut pieces of metal 3/4" wide and 1/8" thick without breaking or becoming too dull to cut after one use?**
A: I couldn't tell you about the quality of the other 9 blades in the pack, I'm still on the first blade. I've cut cast iron rod 1 inch thick ( not fun) and un hardened w1 tool steel rod stock quite a few times and a whole bunch of aluminum rod stock and I haven't even considered changing blades from the first one yet. the catch is these only work really well when they are in a high tension frame. So a standard hacksaw might break them. I wouldn't try cutting 1/8th with this tooth pattern though. Gst the blades with a higher tpi
