CRC TrueTap HD is a thick, oily cutting fluid for tapping and threading in tough metals. Lubri-Loy's interchange list pairs it with Lubri-Cut Heavy Duty, LC3-016: a 16 oz bottle of heavy duty, concentrated, water-soluble semi-synthetic cutting fluid.

These are different forms. TrueTap HD is used neat from the bottle, and Lubri-Cut is a concentrate you mix with water at 5 to 10 percent. This page explains where that matters.

## Quick answer

Lubri-Loy's interchange list pairs CRC TrueTap cutting fluid (bottle) with Lubri-Loy Lubri-Cut Heavy Duty LC3-016 (16 oz bottle). They are not a like-for-like form: TrueTap HD is a neat oil and Lubri-Cut is a water-soluble concentrate.

02The case for switching

## Why choose LC3-016

### Built for heavy-duty machining

Lubri-Loy's catalog describes a balance of cooling and lubrication for extended tool life in machining hard material, with superior chip settling and controlled detergency.

- 02

### Bio-inert ingredients

The catalog says it contains bio-inert ingredients designed to reduce odors and biological growth, and resists depletion due to hard water or microbial action.

- 03

### Bottle to pail

Start with the 16 oz bottle (LC3-016) and move to the 5 gallon pail (LC3-640) for machines with a sump.

### Since 1949

Lubri-Loy has supplied lubricants since 1949. We source, formulate and package through our network of US blending partners.

03Before the changeover

## Check before you switch

A neat tapping fluid and a water-soluble concentrate are used differently. A sump-based machine can run Lubri-Cut diluted; hand tapping with an oily fluid is a different job, so test on your material first.

Check your shop's fluid-management practices and local rules for coolant concentrate handling before you switch.
