In high-precision machining environments, the right cutting fluid is essential for cooling, lubrication, and extending tool life. Whether you're drilling aerospace alloys or grinding automotive components, water-soluble metal removal fluids like HOCUT® 795 B and HOCUT® 795 H are engineered to meet the rigorous demands of modern CNC operations.

In this guide, we’ll break down what these fluids are, what sets them apart, and how to choose the right one for your operation.

Water-soluble metal removal fluids (also called coolants, cutting fluids, or machining fluids) are blends of water and lubricating oils or synthetic compounds. These fluids are designed to:

• Cool the cutting zone
• Lubricate tool and workpiece contact points
• Flush away chips and debris
• Reduce tool wear and extend tool life

Unlike straight oils, water-soluble fluids offer better heat dissipation and easier cleanup — critical advantages in high-speed, high-pressure CNC machining.

HOCUT® 795 B is a semi-synthetic, water-soluble cutting fluid formulated for aerospace manufacturers and high-performance machining. It's known for:

• Low foaming performance, even under high pressure
• Excellent corrosion protection
• Biostable chemistry for long fluid life and reuse
• Free from chlorine, sulfur, and boron

Aerospace Approvals:

HOCUT® 795 B is trusted by top aerospace manufacturers and holds critical OEM approvals, including:

• Boeing BAC-5008 (Classes 1–6)
• Pratt & Whitney PMC 9386-1
• Bombardier BAMS 569-001
• Rolls Royce CSS 129 & 131
• NASA MF0004-018
• Airbus AIPS 00-00-010

This makes it ideal for machining aluminum, titanium, and other aerospace alloys without compromising downstream processes.

For high-speed machining and grinding in automotive operations, HOCUT® 795 H offers dependable cooling and low-foam performance. It's widely used in parts shops and production lines for:

• CNC machining and grinding
• High-pressure applications
• Consistent sump life and cleanliness

Automotive OEM Approval:

• Approved by Honda for manufacturing applications

Its semi-synthetic formula helps reduce maintenance while delivering consistent performance across a wide range of metals.

Both 795 B and 795 H provide:

• • Low foaming under pressure — ideal for high-speed CNC work
  • Chlorine-, sulfur-, and boron-free formulations
  • Biostable additives that help fluids last longer in the sump
  • Excellent surface finish and tool protection
  • Support for fluid recycling and reuse

When selecting a metalworking fluid, consider:

• Your industry requirements (e.g., aerospace vs. automotive)
• OEM or regulatory approvals needed
• Material compatibility (aluminum, titanium, steel)
• Machining process (milling, drilling, grinding, etc.)
• Coolant delivery system (high pressure, through-spindle, etc.)

Quick Comparison:

Whether you're producing aerospace components or automotive parts, the HOCUT® 795 Series offers proven performance, long fluid life, and compliance with demanding OEM standards.
