Drag Bit: rag Bits For Water Well Drilling A drag bit is a drill bit usually designed for use in soft formations such as sand, clay, or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to log. Product Specifications ->Select tungsten carbide inserts 3/16" thick are standard ->Carbide inserts are individually hand soldered using nickel silver rod ->Bits fabricated are welded with high tensile strength 7018 rod ->Drag bits are welded solid at the nose for durability ->Blades originate from 4140 heat-treated tool steel forgings ->Forgings are milled to better seat the carbide inserts ->Relief is hand ground behind carbide inserts for maximum performance ->Bits can be built to the gauge tolerances required
Reusable & washable masks It has been manufactured in Turkey, with the R&D support provided for the development of cloth masks in order to contribute to the fight against the new type of coronavirus (Covid-19). It has been reported that it destroys 99 percent of microorganisms in the accredited laboratory tests we have made in our country on the produced yarn and fabric. The silver ions in the yarn and fabric product produced tears the cell membrane of micro-organisms and destroy the ability of their DNA and RNA to reproduce themselves. In addition, the silver ion, which is the antimicrobial agent in the yarn and fabric product, is trapped inside the yarn, so it maintains its effectiveness on the product for a long time. It is comfortable, easy to use and aesthetic. It can be washed at 60 degrees and reused. It is a 100 percent polyester product with nose wire. The results obtained showed that the masks had 98.8 percent bacterial filtration efficiency and were certified to comply with the European Standard EN 14683: 2019. This level of protection corresponds to the Medical Mask Type 2 class.
Surgical face mask Special - antibacterial Surgical antibacterial facemask, 3-layer, highly efficient, with a plastic strip integrated for its perfect anatomical adjustment. Its BFE (bacterial filtration efficiency) is more than 99,6% and its good breathability (�±16,88 Pa) makes it possible to breath comfortably during long periods of usage. Our face mask is composed of fine nonirritable material, without odour, sensible to the skin. It does not contain latex, glass fibers or other allergens. The antibacterial filter (non woven meltblown PP â?? the inner layer) with active silver particles is covered on both sides with non woven spunbond PP. The high antimicrobial efficiency is made possible thanks to its active component ANSILVER (active silver particles) which is activated only in a humid environment, that is, in contact with nose and mouth. The particles caught (viruses and bacteria) die or become inactive, unable to reproduce themselves. ANSILVER does not volatilize nor ever after long periods of storage. It remains stable in dry environment.
