It measures 0.339 inches in diameter (Letter size R) with an overall length of 3-5\/16 inches and a flute length of 1-9\/16 inches. Constructed from Cobalt Vanadium High Speed Steel, it delivers hardness and heat resistance needed for cutting through stainless steel, cast iron, and other tough workpieces. The bright, uncoated finish and split-point geometry at 130 degrees reduce walking and entry force. A parabolic flute design with web thinning improves chip evacuation and reduces cutting resistance throughout the drilling cycle. This bit is sold individually and is appropriate for use by machinists and trade professionals requiring precision and repeatability.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for universal application across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. It performs in screw machine and general-purpose production drilling environments where shorter length-to-diameter ratios provide rigidity and accuracy. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 25.00 mm (approximately 0.984 inches), it is suited for shallow to moderate-depth holes where a straight-cylindrical shank and compact body keep runout to a minimum. This bit fits standard drill chucks and is commonly used in CNC machining centers, drill presses, and manual screw machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt Vanadium High Speed Steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split-point angle reduces thrust force and eliminates center-punch requirement on most materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry with web thinning promotes efficient chip evacuation and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual wear inspection during service life\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS specification designations for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series A1148 screw machine length drill bit compatible with standard straight-shank drill chucks.

Secure the shank fully in a properly sized chuck and verify concentricity before starting the cut. Power down and de-energize the machine before changing tooling or adjusting workpiece fixturing. Do not exceed the rated drilling depth of 25.00 mm without retracting and clearing chips to prevent flute packing and bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.339 inches (Letter size R)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 25.00 mm (approximately 0.984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0791 inches (2.01 mm)\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\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.00000 inches (-0.022 to 0.000 mm)\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 5153731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51742250238258,"sku":"5153731","price":45.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_59f0bdde-7b12-43bb-a6ed-c9180ab8f47d.jpg?v=1788836197","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153731-screw-machine-drill-bit-0-339-in","provider":"Voomi Supply","version":"1.0","type":"link"}
