Description

The Precision Twist R18A jobber-length drill bit, is a round shank bit made of HSS with a steam tempering finish. It is suitable for drilling to a depth up to four times the diameter of the drill. The shank diameter is the same as the drill size. For best performance, use for drilling into alloyed, hardened and tempered steel, nodular graphite malleable cast iron, titanium, and alloyed nickel. While the R18A series was designed for the aircraft industry, it also works well for drilling into a variety of materials. The jobber length and 118-degree split-point drill geometry provide good reach to the work piece and help ensure a more accurate hole by reducing walking when the hole is started. Steam tempering finish gives a strongly adhering blue oxide surface that acts to retain cutting fluid and prevent chip to tool welding, reducing the formation of a built-up edge. The finish retains lubricant to aid in wear resistance and chip flow. The R18A series has a type N flute form, with a regular helix (21- to 34-degree) angle. Uncoated tools have no finish or coating. They are a common choice for general use applications. The short-stub length has more rigidity for drilling straighter, shallower holes than jobber-length bits. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. Right-hand twist brings chips up and away from the cutting edge. and away from the cutting edge. They are made to ANSI (fractional sizing) and NAS 907 type A industry standards, which ensure that drill bits around the world conform to the same specifications.
