It carries a Letter Q designation, corresponding to a decimal diameter of 0.3320 inches, and features a 135-degree split point for self-centering penetration with reduced walking on hard surfaces. The bit is manufactured from high speed steel with a titanium nitride (TiN) coating that extends tool life in high-cycle production and maintenance applications. A parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and the need for frequent retraction. This bit is sized and configured for use by machinists, maintenance technicians, and metalworking professionals.\u003c\/p\u003e\u003cp\u003eThe 53884 fits standard jobber length applications in metal fabrication shops, industrial maintenance environments, and production drilling operations. Its straight-cylindrical shank seats directly into keyed or keyless drill chucks on drill presses, hand drills, and magnetic base drills without adapters. The 135-degree split point performs best in harder steel alloys where conventional 118-degree points tend to skate. Overall length of 4.75 inches and a flute length of 3.4375 inches provide adequate reach for through-hole work in stock up to approximately 3 inches thick.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter Q size: 0.3320 inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry on steel alloy workpieces\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating improves wear resistance and reduces friction\u003c\/li\u003e\n\u003cli\u003eParabolic flute design accelerates chip removal in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction reduces thrust requirements\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade construction suited for continuous production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for jobber length drill bit applications in steel alloy machining.

Secure the shank fully in the chuck and verify concentricity before drilling. Always power down the drill press or disconnect the hand tool before changing bits. Use appropriate cutting fluid or coolant on steel alloy workpieces to manage heat, even though this bit does not support through-coolant delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.3320 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches\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 Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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: -0.0010 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150DHT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 53884\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733335376178,"sku":"53884","price":30.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1539f4b9c9d875c9bd31c47fa35135c0.jpg?v=1788754366","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53884-letter-q-jobber-drill-bit-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
