Built from micrograin solid carbide with a bright\/uncoated finish, it delivers high performance in short, rigid setups where stub-length rigidity is required. The three-flute, helical parabolic flute geometry promotes efficient chip evacuation. Overall length is 3.5040 inches with a flute length of 1.8504 inches. The straight cylindrical shank and tapered web configuration support accurate positioning and reduced deflection at the cut. This bit is suited for professional machinists and metalworking tradespeople running production or jobsite drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 54617 is engineered for drilling aluminum and non-ferrous metals. Its 124-degree special point geometry and three-margin design make it well-matched for materials that demand clean entry and controlled chip flow. The screw machine length format fits standard drill chucks and short-travel spindles commonly found in drill presses, CNC machining centers, and manual lathes. Maximum drilling depth is 1.8500 inches, making it appropriate for through-hole and moderate blind-hole applications in aluminum plate, bar stock, and extrusions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for high wear resistance in non-ferrous machining\u003c\/li\u003e\n  \u003cli\u003eThree-flute helical parabolic design for efficient chip evacuation and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003e124-degree special point angle optimized for aluminum and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eScrew machine length provides added rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of +0.00024 to +0.00083 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eThree-margin geometry supports precise hole straightness and improved surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting straight cylindrical shanks in the 0.3000 to 0.3500 inch diameter range.

Secure the straight shank firmly in a properly sized collet or drill chuck before operation. Carbide tooling is brittle and susceptible to fracture from side loading or interrupted cuts — avoid lateral force during drilling. Ensure the workpiece is rigidly fixtured and the spindle speed and feed rate are appropriate for carbide in the target material before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 124 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical \/ Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8504 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.8500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5750 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 3\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous Metals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 131N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51747506880818,"sku":"54617","price":206.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d098786ba3ffb081e5615647283246f.jpg?v=1788881543","url":"https:\/\/voomisupply.com\/products\/sgs-54617-screw-machine-drill-bit-letter-q-0-3320-in","provider":"Voomi Supply","version":"1.0","type":"link"}
