A revolutionary new system has appeared at the forefront of the drilling industry – the WINK Vibracore Portable Drill. Small, lightweight and simple to operate, the Vibracorer is built with technology that leaves conventional drilling methods behind. The result of this innovative design is a finely tuned machine capable of drilling intervals of five feet in 60 seconds and penetrating a variety of unconsolidated materials to record depths. And most important, the Vibracorer is able to collect undisturbed, truly representative core samples.

Originally introduced by inventor Fred Wink in 1981, the Vibracorer quickly gained a reputation for high performance in locations where other drills fail. With over 50 years of experience in the drilling industry, Wink perfected his unique sampling system by traveling throughout the world testing and improving the Vibracorer for use in a wide variety of field conditions and geologic formations. Obtain accurate samples quickly and cost effectively – onshore or off – in a wide range of temperatures and conditions.

A New Concept in Sediment Sampling

The Key to the WINK Vibracore Drill is simple – the principle of vibration. The Vibracore drill head, is powered by a 6.5 h.p. Honda engine, generates 7,000 to 12,000 acoustic vibrations per minute and transfers them to the drill string. This action, aided by the weight of the equipment itself, mobilizes the particles coming into contact with the drill rods, instead of churning the sample like conventional drilling methods do.

And because the Vibracorer works by vibration, not by rotation or percussion, there is no need for drilling fluids, which contaminate the sample or hinder operations in remote or severe cold weather.


Dependable Accurate Samples

The vibration frequency of the Vibracorer is adjustable, allowing the operator to tune into the natural frequency of the strata being sampled, control the rate of penetration and collect consistent, intact samples. A continuous soil or sediment sample flows into a core barrel for later retrieval and laboratory analysis.

Conventional soil classification tests, EPA toxicity tests and bio-assay analyses all can be conducted from samples retained in clear plastic or soft poly tubing.


Easy to Transport, Easy to Operate

One of the Vibracorer’s most impressive features is its portability. The drilling power is packed into a snug package, which includes the 37 pound Drill Head, 61 pound Honda driven Power Plant, 27 lb Flex Cable drive cable, Gin Pole hoisting and pull-down system, Drill Rods, Core Bits and Core Retainer spring.

The entire system is easily carried by two people, making it ideal for remote sites and deployment over water and in tight quarters. Save access costs as this drill can be carried by light truck, ATV or helicopter.

The longest piece of equipment is only 62" (1.58m). Once at the site, the Vibracorer and its accessories are simple to operate, with a minimum of previous training required.


Accessories for Even More Versatility

WINK Vibracore also offers carefully designed accessories to streamline the sampling process.

  • The Wink Side Ejector, for example, allows selective sampling.
  • The Wink Vibracorer system offers variable length core collection equipment.

A Wide Range of Applications

The growing number of applications for the Vibracore drill system is testament to its versatile and efficient design. In hazardous waste investigations, geotechnical analyses, studies for environmental purposes, mining and countless other uses, the Vibracorer consistently produces reliable soil and sediment samples and stands up against the most adverse conditions.
