Is it safe to cut food with this?

Is it safe to cut food with this?
Asked by: TimTaylor
Hi TimTaylor, Thank you for your question. This blade is not optimized for cutting wood, however in specific applications it will work, but it depends on the material. You should always wear safety gear and following the safety instructions in the owners manual of your tool. Hope this helps.

What is the TPI? 20 or 24?

I am confused as the TPI is listed at 20 / 24. I'm sure it's some standard but I would like to know exactly what it means. Thanks, John
Asked by: JFS
The 20/24 TPI is a variable tooth design. One inch will have 20 teeth, and the next inch will have 24 teeth. This is based on the 2+2 tooth design that has varying distances between each group of two teeth.

Customer Reviews

9 in. 20/24 Teeth per in. Steel Demon Thin Metal Cutting Reciprocating Saw Blade (25-Pack) is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Outstanding Blade Purchased a couple of these for my reciprocating saw. I figured I would wear them out pretty quick but I had never used this brand and wanted to give it a try. I was installing a ground mount solar array at my house and needed to do a lot of metal post and uni strut cutting along with conduit etc. and components for the chain link fence that goes around the solar array. The teeth on the first blade are as sharp as when I purchased it. I ran through several battery changes with the reciprocating saw but never had to change a blade. It is still sharp and straight. I would recommend this to anyone who has metal to cut.
