Manufactured from cobalt vanadium high speed steel, it carries a 0.397 inch (Letter X) diameter and measures 3.5 inches in overall length. The 130-degree split point reduces walking on entry and lowers thrust requirements, while the parabolic two-flute geometry accelerates chip evacuation. A bright, uncoated finish makes coating wear easy to monitor during use. This bit is intended for installation and use by machinists, tool-and-die workers, and trade professionals requiring consistent hole quality in hard and abrasive workpiece materials.\u003c\/p\u003e\u003cp\u003eThe 5153737 is suited for drilling cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials where a standard HSS bit would lose edge retention too quickly. Its screw machine (stub) length body provides increased rigidity compared to jobber-length bits, making it a preferred choice for drill press, CNC, and turret lathe setups where runout and deflection must be minimized. The 3xD flute-to-diameter ratio and tapered web configuration support deeper penetration up to a maximum drilling depth of 1.1 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 reduces drill walk and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic two-flute design promotes fast, efficient chip removal\u003c\/li\u003e\n\u003cli\u003eScrew machine length body increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration for improved penetration performance\u003c\/li\u003e\n\u003cli\u003eMeets DIN, ISO, and BS dimensional standards for consistent interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new installation for applications requiring a Letter X (0.397 inch) diameter screw machine length drill bit conforming to DIN, ISO, and BS standards.

Secure the shank fully in the chuck to the recommended grip depth before operating. Inspect the cutting edges and web thinning area for wear or chipping before each use, and replace the bit if edge integrity is compromised. Follow machine manufacturer speed and feed recommendations for the specific workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.397 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0924 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00106 to 0.00000 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5153737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51744016728370,"sku":"5153737","price":67.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_f0e6dc7c-d7c9-4991-a596-26e46784b865.jpg?v=1788852973","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153737-screw-machine-drill-bit-0-397-in","provider":"Voomi Supply","version":"1.0","type":"link"}
