Built from high speed steel with a bright, uncoated finish, it features a 0.277-inch diameter, a 118-degree standard point angle, and a web-thinned, tapered web construction that reduces thrust and improves chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. The overall length is 2-11\/16 inches with a 1-1\/2-inch flute length, and the bit weighs approximately 0.04 pounds. Machinists and trade professionals install this bit in screw machine operations requiring consistent, close-tolerance hole production.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for right-hand spiral flute drilling on a range of workpiece materials, with the manufacturer citing titanium as the primary workpiece material. The screw machine length format offers a shorter, stiffer profile compared to jobber-length bits, making it well-suited for CNC machining centers, turret lathes, and screw machine setups where rigidity and runout control are critical. The 2.5xD flute-to-diameter ratio supports efficient chip clearance in moderate-depth holes. It is sold and packaged as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.277-inch (Letter J) diameter with 118-degree standard point angle for general-purpose hole entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction reduces drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for high-performance cutting applications\u003c\/li\u003e\n\u003cli\u003eScrew machine length profile provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for use in standard drill chucks and collet holders accepting a straight-cylindrical shank; part of the Series R42 product line and conforms to ANSI standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools.
