It measures 0.6875 inches (11\/16 inches) in diameter with an overall length of 4-27\/32 inches and a flute length of 2-7\/16 inches. The 130-degree split point reduces walking and cutting force at entry, while the parabolic flute geometry promotes efficient chip evacuation. A web-thinned, tapered web design lowers thrust requirements and improves penetration rates. This bit is sold individually and suited for machine shop, maintenance, and fabrication applications where a shorter, rigid drill platform is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for universal performance across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. The screw machine length format  -  shorter than jobber length  -  provides added rigidity and reduced deflection, making it well-suited for CNC machining centers, drill presses, and turret lathes. The straight cylindrical shank fits standard drill chucks and collet holders without modification. Maximum drilling depth is 1.700 inches (44.00 mm), keeping it appropriate for through-holes and blind bores within that range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.6875 inches (11\/16 inches) diameter with a diameter tolerance of -0.00106 to 0.00000 inches for precision fitment\u003c\/li\u003e\n  \u003cli\u003eCobalt Vanadium HSS construction for heat and wear resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003e130-degree split point minimizes walking and reduces required thrust at drill entry\u003c\/li\u003e\n  \u003cli\u003eParabolic 2-flute geometry with web thinning and tapered web for fast chip evacuation and lower cutting forces\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (4-27\/32 inches overall) delivers increased rigidity versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a broad range of cutting fluids and dry cutting applications\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS standards; Series A1148 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a straight cylindrical shank at 0.6875 inches diameter.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Power down and de-energize the machine before changing tooling. Do not exceed the maximum drilling depth of 1.700 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-27\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.700 inches (44.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1600 inches (4.07 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00106 to 0.00000 inches (-0.027 to 0.000 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5153740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51741936222514,"sku":"5153740","price":113.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_fdda0e7f-dd17-479a-ae69-9f75d0b68873.jpg?v=1788834431","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153740-screw-machine-drill-bit-0-6875-in","provider":"Voomi Supply","version":"1.0","type":"link"}
