Built from solid carbide and finished with an AlTiN (Ti-NAMITE-A) coating, this bit delivers exceptional heat resistance and wear life at elevated cutting speeds. It measures 10.80 mm (0.4252 inches) in diameter with a 145-degree split-point angle and a notched point geometry that promotes accurate entry and reduces walking. Overall length is 102.00 mm (4.0157 inches). Licensed HVAC, plumbing, electrical, and metalworking trades rely on solid carbide construction when drilling alloy steels and titanium where high-speed steel tooling falls short.\u003c\/p\u003e\u003cp\u003eThe SGS 63191 is suited for machining alloy steels and titanium in production environments where screw machine length tooling is required for rigidity and minimal runout. The shorter body of screw machine length bits makes them the preferred choice in turret lathes, screw machines, and CNC machining centers where overhang must be minimized. The 2-flute regular spiral design with a tapered web and web-thinned point supports efficient chip evacuation during deep-hole passes up to 40.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior rigidity and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003eAlTiN (Ti-NAMITE-A) coating provides high-temperature oxidation resistance, extending tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e145-degree notched split-point reduces thrust force and improves entry accuracy without a center punch\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web configuration promotes chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eStraight shank at 12.00 mm (0.4724 inches) diameter fits standard ER and Weldon-style chuck systems\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (3xD flute-to-diameter ratio) provides added rigidity versus jobber-length alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit screw machine length drill bit for use in turret lathes, CNC machining centers, and automatic screw machines accepting a straight shank with a 12.00 mm shank diameter. Primary workpiece materials are alloy steels and titanium.

Ensure the spindle is fully powered down and locked out before loading or removing the bit from the chuck or collet. Verify shank diameter compatibility with the chuck or collet bore before tightening to avoid runout. Coolant-through is not supported on this tool; use external coolant or appropriate dry-cutting lubricant as required by the workpiece material and shop safety guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.80 mm (0.4252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102.00 mm (4.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 55.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm (1.7717 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0076 to +0.0254 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51750468682034,"sku":"63191","price":481.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cdb049d7287df238645efca4f6bdff1_8beabc92-bbab-4d6d-94af-3594d00bd7b1.jpg?v=1788915688","url":"https:\/\/voomisupply.com\/products\/sgs-63191-screw-machine-drill-bit-10-80mm-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
