18" x 3.8mm Plain Cone Disc Tillage Blade 1" x 1-1/8" Square


  • 18" Diameter
  • 9 Gauge thickness
  • 1.75" Concavity
  • 1" x 1-1/8" Dual Square Axle Size
  • Note: When Axle size notates 2 different sizes then it is a dual punched blade that will fit either axle size. Simply quarter turn blade to fit other axle size.
  • Rockwell Hardness Count is 38. Explanation: The Rockwell scale is a hardness scale based on the indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter. When testing metals, indentation hardness correlates linearly with tensile strength. This important relation permits economically important nondestructive testing of bulk metal deliveries with lightweight, even portable equipment, such as hand-held Rockwell hardness testers.
