It is suitable for bandsaws, drill bits, taps, dies, and CNC machines, and is designed to be mixed at 5-10% coolant with 90-95% water. The product emphasizes environmental and health safety with a low-odor, low-mist profile, and recyclability without sacrificing performance.
KOOL MIST #77 Concentrated Coolant — 1 Gallon
Kool Mist #77 is a concentrated coolant designed to dissolve in water to create a clear cutting fluid suitable for machining any metal alloy. It is formulated for broad compatibility with various operations while emphasizing safety for people, materials, machines, and the environment. The concentrate approach enables customization for different machine loads and cutting requirements, while maintaining effective lubrication and cooling across applications.
WVn Clean Mist — Ultra-Concentrated Misting Fluid (1 Quart)
WVn Clean Mist from Winona Van Norman offers an advanced fully synthetic mist coolant that supports sawing, milling, grinding, turning, drilling, and cutting with a misting nozzle. It is designed to prevent distortion and increase the accuracy of cuts by better managing heat and lubrication at the source. The formulation emphasizes high performance in precision machining environments where consistent coolant quality is essential for tool integrity and surface finish.
OriGlam Mist Coolant Lubrication Spray System
OriGlam’s mist coolant system emphasizes value and efficiency, claiming substantial coolant savings and reduced processing time. The system is designed to keep chips clear, improve safety, and lower tool wear through effective mist lubrication. It provides a spray solution for various metalworking tasks and aims to simplify coolant handling while maintaining strong cooling performance in everyday machining environments.
Fusion Cool 2255 — Premium Synthetic Machining Coolant (1 Gallon)
Fusion Cool 2255 is a premium synthetic mist coolant designed for bandsaw cutting, CNC lubrication, plasma table fluid, and other general metalworking tasks. It offers enhanced lubricity under tough cutting conditions and is particularly helpful when tool pressure is high or materials are abrasive. The product is positioned as an effective replacement or cross-over for Kool Mist 77, providing robust tool protection and reliable cooling for demanding operations.
Buying Guide: Key Purchase Considerations
When selecting a mist coolant for machining, consider the following factors to balance performance, safety, and cost:
- Lubricity and cooling capacity: Choose a formulation that provides strong lubrication for tool life and effective heat removal for surface finish and dimensional accuracy. Fully synthetic or semisynthetic variants often offer better lubricity for tough materials.
- Machine compatibility: Ensure the coolant is suitable for your operations (milling, turning, drilling, grinding) and compatible with your machine types (bandsaws, CNC, manual mills).
- Solubility and mixing ratio: Some products are concentrates requiring dilution (e.g., 5-10% with water); others are ready-to-use. Consider storage, handling, and consistency in concentration.
- Safety and hygiene: Look for low-odor and low-mist formulations to reduce workplace exposure and fume concerns. Consider environmental impact and recyclability where applicable.
- Tool wear and finish: Evaluate how the coolant affects tool wear, chip removal, and surface finish, especially on abrasive or high-pressure materials.
- Maintenance and filtration: Some systems benefit from filtration to keep particulates down and extend coolant life. Assess compatibility with your coolant management setup.
- Cost per liter/gallon: Compare concentrate versus ready-to-use options, accounting for dilution rates and tool life improvements to estimate long-term costs.
- Supplier support and documentation: Access to technical data sheets and guidance on mixing, compatibility, and disposal can simplify adoption and compliance.
Across these options, users typically weigh balance between tool protection, cooling efficiency, and ease of use. For environments with high tool wear or demanding materials, premium synthetic or semisynthetic formulations tend to deliver the most consistent results. For general purpose operations, reliable ready-to-use or concentrate systems provide versatility and cost savings while maintaining acceptable performance.
