Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it offers improved surface hardness and wear resistance compared to uncoated HSS tooling. The drill features a 3mm cutting diameter, a 48mm overall length, and an 11mm flute length. With a 2-flute spiral design and a 20-degree helix angle, it evacuates chips efficiently and maintains positional accuracy at the start of a hole. The straight cylindrical shank measures 3mm in diameter, making it compatible with standard collet and drill chuck setups.\u003c\/p\u003e\n\u003cp\u003eThis spotting drill is suited for general purpose machining in job shops, tool rooms, and production environments. It is used to establish a precise starting divot before a twist drill or reamer is applied, reducing walking and improving hole location accuracy. Right-hand cutting direction is standard for conventional CNC and manual spindle setups. The Series 1200 designation places it within OSG's general purpose spotting line, appropriate for use in steel, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree drill point angle for accurate spotting and countersink preparation\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life versus uncoated HSS\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral geometry with 20-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eSingle-ended design with right-hand cut for conventional spindle use\u003c\/li\u003e\n  \u003cli\u003eGeneral purpose tool application suitable for a wide range of machinable materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general purpose spotting drill for use in CNC machining centers, drill presses, and manual mills equipped with collets or drill chucks accepting a 3mm straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators in standard collet chucks or keyless drill chucks. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify runout at the shank before operation to maintain positional accuracy.
