It carries a 0.1562 inch (5\/32 inch) diameter with a 140-degree split point that reduces walking and thrust on entry. The WD1 coating improves wear resistance and extends tool life across a range of workpiece materials. Right-hand spiral flutes with a regular helix evacuate chips efficiently during through-hole and deep-hole operations. Coolant-through capability channels fluid directly to the cutting zone, making this bit well suited for CNC machining centers and automated drilling cycles where heat and chip management are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in metalworking environments where tighter tolerances and longer reach are required than a jobber-length bit can provide. The taper length body gives additional flute depth for applications such as drilling into thick stock, stacked plates, or components that demand a cleaner exit hole. The 8xD flute-to-diameter ratio supports deep-hole drilling strategies. It is typically installed in CNC machining centers, drill presses, or manual mills by machinists and toolroom technicians working with ferrous and non-ferrous metals, composites, or engineered plastics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in production drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point reduces entry thrust and minimizes walking\u003c\/li\u003e\n  \u003cli\u003eWD1 coating enhances wear resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for deep-hole work\u003c\/li\u003e\n  \u003cli\u003e8xD flute-to-diameter ratio supports taper length deep drilling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production tooling option for applications requiring a 5\/32 inch diameter taper length carbide drill bit in the OSG HP258 series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and toolroom technicians using a compatible drill chuck or collet system matched to the 4 mm shank diameter. Always power down and de-energize the machine spindle before changing tooling. Confirm runout and tool projection before beginning a cycle, and verify that the coolant-through circuit is active and unobstructed before drilling at full depth. Follow the machine tool manufacturer guidelines and applicable shop safety protocols when handling carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 85 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP258\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP258-1563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752180351282,"sku":"HP258-1563","price":200.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e37ba4651ece56353976c122d5aa973.jpg?v=1788926386","url":"https:\/\/voomisupply.com\/products\/osg-hp258-1563-taper-length-drill-bit-5-32-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
