Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it cuts at 13.50 mm (0.5315 inches) in diameter and features a 120-degree faceted point for accurate entry and reduced walking on hard materials. The web-thinned, tapered web design lowers thrust requirements and improves chip evacuation through its two spiral flutes. Overall length is 114 mm (4.49 inches) with a 54 mm flute length. This bit is intended for use by machinists, tool-and-die workers, and maintenance technicians running drill presses, CNC machines, or manual mills.\u003c\/p\u003e\u003cp\u003eThe OSG 61635 is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine (stub) length provides added rigidity compared to jobber-length bits, making it a practical choice for close-tolerance work in production environments, machine shops, and maintenance facilities. The Series 1100 classification places it in OSG high-performance tooling, appropriate for moderate to high cutting speeds in ferrous and non-ferrous applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13.50 mm (0.5315 inches) cutting diameter with a diameter tolerance of +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e120-degree faceted point for self-centering entry and clean hole initiation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length adds rigidity for tight setups and close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute, 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks; the 16.00 mm (0.6299 inches) straight-cylindrical shank fits drill presses, CNC machining centers, and hand drills with appropriate chuck capacity.

Secure the shank fully in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid or coolant for the workpiece material, noting that this bit does not have through-coolant capability. Inspect the cutting edges for wear or chipping before each use; a worn TiN-coated bit should be replaced rather than reground without specialized equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.50 mm (0.5315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 114 mm (4.49 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 54 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16.00 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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 Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754627694898,"sku":"61635","price":225.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313f5622390083b834fdea142baaccd6.jpg?v=1788947234","url":"https:\/\/voomisupply.com\/products\/osg-61635-screw-machine-drill-bit-13-50mm-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
