Tungsten content in hss planer knives enhances hardness, heat resistance, and wear resistance. A higher tungsten percentage, such as 18% in T-1 HSS, delivers a harder and longer-lasting edge compared to standard M2 HSS, which typically has around 12% tungsten. This means less frequent sharpening and better performance under heavy or continuous use. For example, the Amana Tool P 390 and Amana Tool P 290 both feature 18% tungsten for increased durability. Multiple options are available, so you can select the tungsten content that best matches your shop's workload. I only use the Amana brand Bits and blades for uninterrupted service and great outcomes.
