Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 130-degree, 4-facet point geometry with web thinning reduces thrust force and improves centering accuracy at the start of each hole. At 50.00 mm overall length with an 18.00 mm flute length, it fits standard screw machine and CNC drill press setups. Machinists and tool-and-die professionals are the primary users of this style of bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, aluminum, and other non-ferrous metals in high-cycle production applications. Its screw machine length — shorter than jobber length — provides added rigidity and reduced deflection, making it well suited for close-tolerance work on drill presses, turret lathes, and CNC machining centers. The regular spiral flute design ensures consistent chip evacuation across a range of work materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e130-degree 4-facet point improves self-centering and reduces thrust at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides greater rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, aluminum, and non-ferrous workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit for use in standard straight-shank drill chucks on CNC machining centers, turret lathes, and drill presses where a 4.00 mm shank diameter is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or tool room personnel. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation and verify runout before cycling. Follow all machine guarding and PPE requirements per shop safety standards.
