Sized at 7\/16 inch (0.4375 inch) diameter, it features a 130-degree point angle and three spiral flutes in a regular helix configuration for efficient chip evacuation. The bright (uncoated) finish suits applications where coating is not required or where re-sharpening is anticipated. With an overall length of 4.37 inches and a flute length of 2.60 inches, it fits standard jobber-length tooling setups. This bit is specified to DIN 6537L and carries a K10 carbide material grade, making it appropriate for machinists and toolroom professionals working in high-volume drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and manual machine tools requiring a straight-cylindrical shank interface. The web-thinned, parallel-web geometry reduces thrust force at entry, which is beneficial when drilling harder or abrasive materials. The 7\/16 inch straight-cylindrical shank with a shank diameter of 0.4375 inch fits standard collets and drill chucks without modification. It is a right-hand cut tool intended for conventional clockwise-rotation spindles. The 2.09-inch maximum drilling depth accommodates typical through-hole and blind-hole applications within the jobber length class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K10 grade construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with standard point type for accurate entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eThree spiral flutes with regular helix for balanced chip flow and cutting stability\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design reduces thrust and improves penetration efficiency\u003c\/li\u003e\n\u003cli\u003eBright finish allows visual inspection of cutting edges and facilitates re-sharpening\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537L specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill for machining applications requiring a 7\/16 inch straight-cylindrical shank solid carbide bit conforming to DIN 6537L within the 0.4000 to 0.5000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify collet or chuck capacity matches the 7\/16 inch shank diameter before clamping. Coolant-through is not supported on this bit, so external coolant or cutting fluid delivery should be used as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.60 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright (Uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0003 to +0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.222 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1153184\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":67909634130226,"sku":"1153184","price":555.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/135ce2f781a83ea93b271dd69c7125ff_5dd4325c-d5ee-4a1a-b5ee-b29f8c4dda83.jpg?v=1791189407","url":"https:\/\/voomisupply.com\/products\/kennametal-1153184-carbide-jobber-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
