Built from high-speed steel (HSS) with an oxide coating for added surface hardness and lubricity, this bit measures 1.10 mm in diameter with an overall length of 28.00 mm (approximately 1.10 inches). The 118-degree standard point angle is suited for general-purpose drilling across a wide range of workpiece materials. A web-thinned, parallel-web construction reduces thrust at the cutting edge, making it easier to start and maintain hole accuracy at small diameters. Machinists, maintenance technicians, and tool-and-die professionals are the primary users of this bit size.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for screw machine, CNC, and bench-drill applications where a shorter overall length provides added rigidity and improved hole straightness. The straight cylindrical shank seats securely in standard drill chucks and collet holders. Its general-purpose grade and small diameter make it well suited for tapping pilot holes, instrument work, PCB drilling, and precision metalworking tasks requiring close dimensional tolerance at sub-2 mm diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.10 mm diameter (0.0433 decimal inch) for sub-2 mm precision drilling\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide coating for surface hardness and reduced friction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose material entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces thrust and improves centering on small-diameter holes\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit for use in standard drill chucks and collet holders accepting straight cylindrical shanks in the 0.00 to 3.50 mm drill bit size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or maintenance technician in a drill press, CNC machine, or hand-held power drill with an appropriate chuck capacity for sub-2 mm tooling. Secure the shank fully in the chuck or collet before running the spindle, and verify runout before drilling to prevent bit breakage at this diameter. At 1.10 mm, feed rate and spindle speed must be appropriate for the workpiece material; excessive feed pressure is the most common cause of breakage in small-diameter HSS bits. Coolant-through operation is not supported by this bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.10 mm (0.0433 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 28.00 mm (1.10 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01290550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697404018994,"sku":"01290550","price":37.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43d32ebc90b895be7748c3183bc6901c.jpg?v=1788351321","url":"https:\/\/voomisupply.com\/products\/value-collection-01290550-screw-machine-drill-bit-1-10mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
