The Winkie Drill is an agile, commercially available rock coring system. The U.S. Ice Drilling Program has modified a Winkie Drill for subglacial rock and ice/rock interface coring, as well as drilling and coring access holes through ice. The original gasoline engine was replaced with an electric motor though the two-speed gear reducer and Unipress hand feed system were maintained. Using standard aluminum AW34 drill rod (for 33.5 mm diameter core), the system has a depth capability of 120 m. The drill uses forward fluid circulation in a closed loop system. The drilling fluid is Isopar K, selected for favorable properties in polar environment. When firn or snow is present at the drill site, casing with an inflatable packer can be deployed to contain the drill fluid. The Winkie Drill will operate from sea level to high altitudes and operation results in minimal environmental impact. The drill can be easily and quickly assembled and disassembled in the field by two people. All components can be transported by Twin Otter or helicopter to the field site.

Winkie 钻机适用于冰下基岩采样

Winkie 钻头是一种灵活的商用岩石取芯系统。美国冰钻计划修改了 Winkie 钻头，用于冰下岩石和冰/岩石界面取芯，以及在冰上钻孔和取芯。尽管保留了两速齿轮减速器和 Unipress 手动供料系统，但原来的汽油发动机被电动机取代。使用标准铝制 AW34 钻杆（用于直径 33.5 mm 的岩心），该系统具有 120 m 的深度能力。该钻机在闭环系统中使用正向流体循环。钻井液是 Isopar K，选择在极地环境中具有良好的性能。当钻井现场出现冰雪或积雪时，可以部署带有充气封隔器的套管来容纳钻井液。Winkie Drill 将从海平面到高海拔地区运行，运行对环境的影响最小。该钻机可由两人在现场轻松快速地组装和拆卸。所有组件都可以通过 Twin Otter 或直升机运输到现场。
