Rated 4.8 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Works well, competitive price I use these blades in a Ryobi Model P523 jig saw and have had good service from them. The price is competitive, the fit and finish on the blades is excellent, and I have yet to have one break during use. Cutting is smooth and I am not seeing jagged edges or splinters from these blades. Recommended. HTH August 27, 2015
Rated 5.0 out of 5.0 by Worth the money! I bought this packet for a mini project I was doing to convert my washing machine drum into a fire pit. Initially skeptical that these erupted cut through the thick metal,I bought them was pleasantly surprised when it made a smooth cut. I would recommend this product to new DIY'ers looking for a cheap metal cutting saw. I can't wait to use them again! June 12, 2014
