I am selling these items because I purchased them but they were the wrong size (the hole diameter of this item is 20mm). This is a set of two similar items. Both have a hole diameter of 20mm. Since it's priced as a set of two, isn't it a great deal? [Grass Cutting Blades] The Makita A-20797 is a 160mm grass cutting blade that efficiently cuts weeds. It is especially suitable for use in gardens and agricultural work. [Chip Saw] The NAFCO NF385 is a 160mm chip saw with 36 teeth, suitable for grass cutting. It boasts high durability and precision. - Brand: Makita - Model Number: A-20797 - Size: 160mm - Application: Grass Cutting - Brand: NAFCO - Model Number: NF385 - Size: 160mm - Number of Teeth: 36 - Hole Diameter: 20mm - Application: Chip Saw Thank you for viewing.
