Batch casting of rim sprockets for chain saws as particularly applied to larger rim sprockets experience undesired high scrap rate resulting from porosity and chip-out. The solution is to ensure flow of molten steel throughout solidification of the molten steel in the sprocket mold while retaining molten steel portals or gates of a size that permits breakaway of portal stems. Such enhances the cooling rate of the molten steel in the sprocket mold which was found beneficial. The objective of reduced scrap rate is thus accomplished by maintaining a ratio of mass to surface area of the sprockets being cast to no greater than about 4 grams of material to each square inch of surface area and alternatively provide through bores through the rim sprockets which additionally assist in wood chip removal. This design also reduces the material content which reduces the cost and weight of the product.
