Built from M2 high-speed steel with a straw (bronze) coating, it features a 135-degree split point that reduces walking and improves bite on hard and high-temperature alloy workpieces. The web-thinned, tapered web design lowers thrust requirements during entry. At 4 inches overall length with a 2.75-inch flute and a straight cylindrical shank, this bit is sized for standard drill chucks and compatible with most benchtop and handheld drilling setups used by machinists, fabricators, and maintenance trades.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling into high-temperature alloys, ferrous metals, and general structural materials in production, maintenance, and repair settings. The HX10-HX15-HX18 series designation places it within a family of M2 HSS jobber drills engineered for consistent performance in both CNC and manual drilling operations. The right-hand cutting direction and regular spiral flute geometry support efficient chip evacuation in through-hole and blind-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high-speed steel construction rated for heavy-duty and high-temperature alloy drilling\u003c\/li\u003e\n\u003cli\u003e135-degree standard split point reduces bit walking and improves penetration on hard materials\u003c\/li\u003e\n\u003cli\u003eStraw (bronze) coating provides surface lubricity and heat resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers drilling thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry promotes clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the PRECISION TWIST DRILL Series HX10-HX15-HX18.

Secure the shank fully in the chuck and confirm concentricity before beginning a cut. Power down and de-energize all equipment before changing bits. Do not exceed the rated drilling depth of 2.75 inches and ensure appropriate feeds and speeds are observed for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M2 High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw (Bronze)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HX10-HX15-HX18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose \/ Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996329\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691499290930,"sku":"5996329","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28291d695eb6c90708270d4dadfdae7d.jpg?v=1788285997","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996329-letter-b-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
