Spiralbohrer, 19 mm Schneide, geeignet zum Bohren von Edelstahl, Aluminiumlegierungen, Eisen und Kupfer.

★ Drill Bit Size--- Cutting Diameter: 19mm / 0.75"; Shank Diameter: 10mm / 0.39"; Cutting Length: 57mm / 2.24"; Overall Length: 150mm / 6"; Shank Type: Three-Flat Shank (for tighter clamping and more precise drilling). ★ Wide Applications--- Widely used for drilling stainless steel, aluminum alloys, iron, copper, brass, and hardwood. Suitable for vertical drilling machines and bench drills. Reduced diameter drill bits expand the size range of portable drill chucks. ★ Double Coating--- A double coating of gold titanium and black nitride allows for better lubrication, smoother drilling, and is more durable and corrosion-resistant than a plain black finish. ★ High-Speed Steel--- Straight shank drill bits are made of high-quality materials with high hardness, high toughness, high strength, and wear resistance. Sharp helical flutes enable fast, clean, and smooth cutting. ★ Practical Tips--- Choosing the right lubricant is beneficial for cutting and cooling. It can improve cutting, increase dimensional accuracy, and extend tool life. Please check different cutting conditions to ensure proper tool operation.
