It measures 27\/64 inches (0.4219 inches) in diameter with a 5-7\/8 inch overall length and a 3-15\/32 inch flute length. The 118-degree point angle provides a balanced entry geometry suited to softer non-ferrous workpieces. A Diamond-Like Carbon (DLC) coating reduces friction, resists built-up edge, and extends tool life in high-volume production environments. The straight cylindrical shank seats securely in standard drill chucks and collet holders. This bit is sold individually and is intended for use by machinists, tool-and-die professionals, and maintenance technicians operating drill presses, CNC machining centers, or handheld power tools.\u003c\/p\u003e\u003cp\u003eThe 4500297 is engineered for cutting aluminum, copper, brass, and other non-ferrous materials where heat generation and chip adhesion are primary concerns. Its regular spiral flute geometry promotes consistent chip evacuation along the full 3.4688-inch flute length. The coolant-through design supports through-spindle coolant delivery, making it well suited for deep-hole applications on CNC equipment where flood coolant alone may not reach the cutting zone. The 5xD flute-to-diameter ratio is appropriate for standard jobber-length drilling depths in production machining and precision fabrication shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eDLC coating reduces friction and inhibits chip welding on aluminum and soft metals\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports through-spindle coolant delivery for deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e118-degree point angle provides balanced entry geometry on non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit for use in drill presses, CNC machining centers, and handheld power tools equipped with a chuck or collet accepting a 27\/64 inch (0.4219 inch) straight shank.

Ensure the shank is fully seated and the chuck or collet is torqued to the tool holder manufacturer specification before operation. Through-spindle coolant connections should be verified and secured before running at speed. Inspect the cutting edges for chipping or wear before each use, as carbide tooling is brittle and can fail without visible warning if dropped or mishandled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inches (0.4219 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches (5.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-15\/32 inches (3.4688 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 27\/64 inches (0.4219 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eCoating\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500297\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733992177970,"sku":"4500297","price":335.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8792e620fe19f0276ab08777e1986835.jpg?v=1788760369","url":"https:\/\/voomisupply.com\/products\/accupro-4500297-jobber-drill-27-64-in-solid-carbide-dlc","provider":"Voomi Supply","version":"1.0","type":"link"}
