Titanium Plated High Speed Steel (HSS) Drill Bits Set Cutters for Stainless Steel Aluminum Alloy Plastic 10 Per Pack of Each Size. 1- Package Contents – 10 Pieces x Factory Trade Priced HSS. (high speed steel) hole saw kit cutter set with L-wrenches. Triangular shank, works with hand-held drills max size efficiency, drill presses, bench drills. Care must be taken when hand held or the teeth will break if the items bounce about. Constructed from High Speed Steel (HSS) and titanium coated for added strength, the hole saw combines high hardness, toughness, wear resistance, heat resistance to provide excellent durability, precision and long-lasting performance in a variety of materials and applications. The high-speed steel (HSS) hole saw can cut clean and precise holes in thin metals (aluminum, copper), plastics. NOT suitable for ceramic, tile, concrete, stone, and NOT for metals thicker than 5mm. The sharp cutting teeth can create precise, smooth and clean cuts with minimal burring or chipping. Slowly apply pressure otherwise you may damage the threads. Titanium plating increases hardness, corrosion resistance, heat resistance and reduces friction for better performance and longer life. Apply lubricant or cutting oil on the cutting edge to reduce friction and prevent overheating. Hold the hole saw firmly when drilling. Use the recommended cutting speed to cut the material. Start drilling with light pressure and gradually increase as needed. The power of hand electric drill needs to be greater than 750W. Do not use on the impact drill and electric hammer. Use in slow speed, minimum pressure, and keep the hole saw stable when cutting materials. Keep the cutter cool and lubricated during drilling. High-speed steel and stainless steel hole saws, drill saws, sheet metal reamers. The hole opener adopts spring design, which is conducive to chip removal and superior drilling performance. High precision, smooth cutting edge, especially impact resistance and wear resistance. Due to special heat treatment, sharp edges, high strength. Hole saws will help you drill large diameter holes in metal, aluminum plates, alloy plates, plastic plates, stainless steel, mild steel, iron, copper and brass, etc. Material: HSS high speed steel. When using this item, the cutting material needs to be fixed and cannot be moved. It should be 90 degrees perpendicular to the drill bit. When the center drill bit penetrates the drill bit, please wait a while, and then slowly drill the hole. When drilling, if you think the drill bit is abnormal or the waste is not ideal, please stop drilling, take out the chips, and then continue drilling. In order to extend the service life of the drill bit, it is important to use cutting lubricant when drilling. In order to obtain the maximum hole saw life, when drilling stainless steel or steel, please use a speed lower than 300 RPM.
