The YG-1 D2GP185019 is a high speed steel jobber-length drill bit with a titanium nitride (TiN) coating and a 135-degree split point. It is designed for general-purpose drilling applications in steel and similar metals. The split point geometry reduces walking at the start of a hole and requires no center punch on most workpieces. At 4.375 inches overall length with a 3.0625-inch flute length, it delivers the reach and chip clearance expected in production and maintenance drilling environments. Licensed machinists, tool-and-die techs, HVAC fabricators, and field service professionals reach for this size when standard jobber reach is required for 19/64-inch diameter through-holes.
This drill bit is suited for drilling steel, structural iron, and ferrous alloys in residential and light commercial service work, fabrication shops, and mechanical rooms. The 19/64-inch diameter (0.2969 inches decimal) is commonly used for clearance holes, tapping pre-drill operations, and sheet metal work where a precise fractional size is specified. The right-hand spiral flute configuration pulls chips up and out of the hole during standard clockwise drilling. The TiN coating extends surface hardness and reduces friction, making it a practical choice for repetitive drilling cycles without regrinding as frequently as uncoated HSS bits.
Designed as a general-purpose jobber drill bit for use in standard 3-jaw drill chucks, drill presses, and handheld electric drills that accept a straight cylindrical shank. Primary workpiece material is steel; the TiN coating also supports use in other ferrous metals under general-purpose cutting conditions.
Secure the straight shank firmly in a 3-jaw chuck before use and confirm the bit runs true with minimal runout. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable shop safety standards and OSHA guidelines for rotating machinery. Allow the bit to cool between deep drilling passes, and retract periodically to clear chips and prevent heat buildup.
