Product Details
Left hand black oxide surface treated screw machine length drills are primarily designed for machining operations in screw machines. Their short length offers increased rigidity for machine drilling a variety of materials and alloys, making them best suited for drilling steel, cast steel, cast iron, or other alloyed or non-alloyed ferrous materials, while also being effective for a range of non-ferrous and non-metallic materials. These drills may be used with hand-held manual drills as well as both portable and stationary machines. For optimal performance and tool life, the use of suitable lubricating or cutting oils and appropriate coolant fluids is recommended. Key features include left hand (counter-clockwise rotation) cutting direction, a standard two flute design, standard spiral helical flutes, and straight shanks corresponding to the drill diameter, with drill lengths proportional to the diameter. Technical specifications indicate that these drills are manufactured from high speed steel, feature precision cylindrically ground flutes, and have a black finish.
