Fully Ground Jobber Drill Bits made from High Speed Steel (HSS) for excellent hardness, toughness, and wear resistance. These drill bits are titanium coated for extreme durability and heat resistance, making them ideal for fast drilling into tough surfaces including all types of stainless steel. The 118-degree split point design allows for quicker penetration with less pressure, minimizing bit walking and ensuring a crisp, centered hole without the need for a center punch. Suitable for hard metals like stainless steel, steel, and cast iron, as well as wood, aluminum alloy, and other softer metals. Adjust RPM if penetration is difficult. UK Drills has been providing high-quality drill bits for over 30 years, covering applications from wood and tiles to masonry.
