Manufactured from high speed steel with a bright uncoated finish, this bit measures 0.2280 inches in diameter (No. 1 wire size) and features a 135-degree split point that reduces walking and improves hole entry without a center punch. The parabolic flute geometry promotes efficient chip evacuation and reduced heat buildup during high-feed drilling cycles. At 3.875 inches overall length with a 2.625-inch flute, it fits standard jobber-length applications in both hand-held and machine setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for metal fabrication shops, maintenance and repair operations, and production drilling environments where steel alloy is the primary workpiece material. The straight cylindrical shank accepts standard drill chucks on bench-top drill presses, CNC machining centers, and portable drills. The Series 150DH designation identifies it as a heavy-duty general-purpose bit built for consistent performance in production or field settings where tool life under load is a priority. Right-hand cut geometry is standard for conventional drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and improves self-centering on flat and curved steel surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip removal and lowers heat accumulation during deep drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces thrust force required at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness and wear resistance in steel alloy applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection for wear and edge condition\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with 0.2280-inch diameter fits standard chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit jobber length drill bit for use in standard three-jaw drill chucks accepting straight cylindrical shanks in the 0.2000 to 0.2500 inch diameter range, including bench drill presses, portable electric drills, and compatible CNC toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and verify concentricity before beginning a cut. For machine use, confirm spindle speed is appropriate for the workpiece material and bit diameter per standard machining references. Inspect the cutting edges and split point before each use and replace or resharpen when edge degradation is visible. Do not force the bit through material at feeds that cause excessive heat or chatter, as this accelerates wear and can cause premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 inches\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: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150DH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738386661682,"sku":"69001","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81eb6748fc3f6e4e8e0686453c6165cb.jpg?v=1788798926","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-69001-jobber-drill-bit-no-1-hss-135","provider":"Voomi Supply","version":"1.0","type":"link"}
