ULTRACUT® EVO 280 – Biocide-Free Aluminium Cutting Fluid

General Description

ULTRACUT® EVO 280 is a high-performance water mix cutting fluid from ROCOL®, uniquely formulated for machining aluminium and aluminium alloys — distributed in Vietnam by PROSTECH. Non-staining on most aerospace and industrial alloys, it prevents built-up edge and promotes excellent surface finish. Biocide-free and skin sensitiser-free, with dilution 15:1 to 25:1.

ULTRACUT® EVO 280 is a water-mix cutting fluid developed by ROCOL® specifically for machining aluminium and aluminium alloys. Its unique formulation creates a stable lubricating film on aluminium surfaces, preventing built-up edge (BUE) — a common problem when cutting aluminium with conventional fluids that leads to poor surface finish and increased tool wear.

Beyond aluminium, EVO 280 is also suitable for copper, copper alloys, and most ferrous metals that are not excessively difficult to machine. Its dilution range of 15:1 to 25:1 (lower than EVO 250/255/260) reflects the specific lubrication demands of aluminium, while still providing good economy. The product is non-staining on most aerospace and industrial alloys.

Like all EVO products, EVO 280 contains no biocides or skin sensitisers, meeting OHSAS 18001 and ISO 14001 requirements. The combination of aluminium-specific formulation and inherent biostability makes it a comprehensive solution for aluminium machining workshops, aerospace manufacturers, and electronics production facilities.

FAQ Section

What is ULTRACUT EVO 280?

ULTRACUT® EVO 280 is a high-performance water mix cutting fluid from ROCOL® (UK), uniquely formulated for machining aluminium and aluminium alloys. Biocide-free, skin sensitiser-free, and non-staining on most aerospace and industrial alloys. Dilution range is 15:1 to 25:1.

Why use a dedicated aluminium cutting fluid like EVO 280?

Aluminium has a high tendency to adhere to cutting tools, causing built-up edge (BUE) — aluminium deposits on the cutting edge that degrade surface finish and increase tool wear. EVO 280 is specifically optimised to prevent BUE, and its non-staining formulation avoids discolouration — a critical requirement in aerospace and electronics manufacturing.

What is the dilution ratio of ULTRACUT EVO 280?

ULTRACUT EVO 280 is used at 15:1 to 25:1 — lower than EVO 250/255/260, reflecting the specific lubrication demands of aluminium. Refractometer readings: 15:1 = 6.2; 20:1 = 4.8; 25:1 = 3.8. Richer dilutions are recommended for thin aluminium sheet or operations requiring a superior surface finish.

Can EVO 280 be used on metals other than aluminium?

Yes. EVO 280 is also suitable for copper, copper alloys, and most ferrous metals that are not excessively difficult to machine. However, if a workshop machines a wide variety of materials and wants to rationalise to a single fluid, EVO 250 or EVO 255 offer more material flexibility — EVO 280 is best when aluminium represents the majority of operations.
