Coolant Systems

About Coolant Systems

Coolant systems are essential equipment for maintaining optimal cutting temperatures during machining and drilling operations. These specialised systems deliver a controlled flow of coolant fluid directly to the cutting zone, helping to dissipate heat, flush away swarf, and improve surface finish quality. MyToolShed.co.uk supplies professional coolant systems including flexible hose assemblies, air-liquid starter kits, and dedicated systems designed specifically for pillar drills and metalworking machinery.

Professional coolant systems typically feature adjustable nozzles, quick-connect couplings, and mounting hardware for precise positioning of coolant flow. Air-liquid systems combine both compressed air for chip clearing and liquid coolant for temperature control through integrated hoses, offering versatility for different machining operations. From compact starter kits ideal for small workshops to comprehensive systems for industrial applications, investing in quality coolant delivery equipment improves tool longevity, machining accuracy, and workplace safety.

Applications

Coolant systems are utilised across various trades and industries where precision metalworking is essential:

• Machinists and CNC Operators: Maintaining consistent temperatures during precision turning, milling, and drilling operations
• Engineering Workshops: Both small fabrication shops and larger manufacturing facilities requiring proper coolant management
• Tool and Die Makers: Precise coolant delivery for intricate tooling work and maintaining tight tolerances
• Metal Fabricators: Drilling, cutting, and shaping operations benefiting from effective coolant delivery
• Maintenance Engineers: On-site machining and repair work where portable coolant systems prove invaluable
• Automotive Workshops: Precision drilling and machining work on engine blocks, heads, and components
• Technical Colleges: Apprenticeship training centres teaching machining skills

Choosing The Right Coolant Systems

Machine Compatibility: Ensure the coolant system suits your specific equipment. Some systems are designed for pillar drills, whilst others offer universal mounting options. Check mounting dimensions and weight capacity before purchase.

System Type: Standard coolant systems deliver liquid coolant only, whilst air-liquid systems provide both compressed air and liquid delivery through integrated hoses. Air-liquid systems typically operate at standard workshop compressed air pressure (6-8 bar) and offer greater versatility.

Flow Rate and Pressure: Consider the volume of coolant required for your operations. General drilling typically needs 2-5 litres per minute, whilst heavy-duty milling may require higher flow rates. Look for systems with adjustable flow control.

Hose Length and Flexibility: Adequate hose length allows proper positioning without strain. Quarter-inch diameter hoses are common for general workshop applications and provide good balance between flexibility and flow capacity.

Ease of Installation: Starter kits available at MyToolShed.co.uk include all necessary fittings and mounting hardware, offering excellent value for first-time installations. Systems with quick-connect couplings facilitate easy movement between machines.

Safety Information

COSHH Compliance: All metalworking fluids fall under COSHH regulations. Maintain appropriate safety data sheets, use recommended PPE including safety glasses, and ensure adequate workshop ventilation. Some coolants may cause skin irritation with prolonged exposure.

Slip Hazards: Coolant spillage creates significant slip risks. Maintain clean workshop floors and use absorbent materials immediately for spills. The HSE identifies slips on contaminated floors as a major workshop hazard.

Pressure Safety: When using air-liquid systems with compressed air supplies, ensure all fittings are properly secured and rated for workshop pressure. Inspect hoses regularly for wear or damage that could cause sudden failure.

Frequently Asked Questions

What's the difference between air-liquid and standard coolant systems?

Air-liquid systems combine both compressed air and liquid coolant delivery through integrated hoses, offering versatility for operations requiring chip clearing (air) and cooling/lubrication (liquid). Standard systems deliver only liquid coolant. Air-liquid systems are particularly useful where you need to switch between dry machining with air blast and wet cutting operations without changing equipment.

Can I use any type of coolant fluid with these systems?

Most coolant systems accommodate standard water-soluble cutting fluids and cutting oils, but always verify material compatibility. Some hose materials may degrade with certain synthetic coolants. Check manufacturer specifications and consider the materials being machined—aluminium, stainless steel, and cast iron may each benefit from different coolant formulations.

How do I maintain my coolant system?

Regular maintenance includes inspecting hoses for cracks or wear, cleaning nozzles to prevent blockages, checking connections for leaks, and flushing the system periodically to remove accumulated swarf. Replace coolant fluid when it becomes discoloured, develops odour, or shows reduced performance. Store systems drained and clean when not in regular use.
