Manufactured in aluminium. Designed to sample powders, granules and semi-solid, caked materials from tanker vehicles and silos. In use the drill is screwed into the media with the scraping sample chamber shutter closed. The shutter is opened at the required depth and the sample taken by twisting the drill. The scraper edge to the shutter will ensure more dense materials are sam- pled. The shutter is then closed and the drill withdrawn for sample analysis. Total length x diameter 1500 x 40mm, screw spirals 80mm diameter. Depths up to 3 metres can be reached by using accessory extension rods.
