Brownells Tough-Quench Quenching Oil is developed specifically for predictable, controlled, fast quenching speed to consistently give a uniform, high oil quenching hardness. Oil soluble agents wet out work rapidly, preventing formation of gas pockets, with less smoke and a low rate of heat transfer to minimize distortion and cracking of the steel. This professional-grade quenching medium is ideal for gunsmithing, toolmaking, and heat-treating applications where precise hardness and minimal warping are essential.
This 1-quart container (16 fl. oz./946 ml) is available in convenient cans, with larger 1-gallon (128 fl. oz./3.8 L) sizes also offered. The product features a flash point of 355°F (179.4°C) and a fire point of 410°F (210°C). The oil can be shipped via UPS, making it accessible for shipment to Arms East locations and customers nationwide.
Whether you’re performing blade hardening, tool steel quenching, or other heat-treat work, Brownells Tough-Quench delivers the controlled cooling rate and reliability that professional gunsmiths and craftspeople depend on. The proven formula reduces smoke and prevents the gas pockets that compromise hardness, ensuring consistent, professional-quality results every time.
