Blue Demon - Rock Cutter Blade

Rock Cutter Blades are low-cost, replaceable blades for soft formations and are forged of tough alloy steel. They are hardfaced on the cutting surfaces with tungsten carbide particles of maximum hardness made to Blue Demon specifications. These heat-treated blades are highly efficient in abrasive formations because of their self-sharpening characteristics. This permits maximum drilling speed until the blade fingers are completely worn away, without loss of gage. The fingers are designed to chip and peel out the formation for fast penetration and speedy cuttings removal.
