Thumb Tip Radius and Bucket Compatibility Tip radius measurement in the chart below is the maximum tip radius allowed for compatibility with the thumb. For pin-on machine configurations, this number should be compared to the bucket tip radius to determine compatibility. For machines with couplers, this number should be compared to the overall tip radius of the bucket and coupler together to determine compatibility.
