Built from solid carbide grade KCP15B, it features a multilayer AlTiN and TiN coating that extends tool life and supports elevated cutting speeds. The 140-degree split point reduces thrust and promotes accurate hole entry without a center punch. With an overall length of 66.00 mm and a flute length of 28.00 mm, this stub-length geometry offers rigidity in short-reach setups. It is suited for use in CNC machining centers, drill presses, and automated screw machine applications where tight tolerances and consistent hole quality are required.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling steel in production machining environments, both light manufacturing and heavy shop floor applications. The 3xD flute-to-diameter ratio and straight cylindrical shank make it compatible with standard drill chucks and collet systems. The HPX series is engineered for applications where tool changes are frequent and cycle time matters. A maximum drilling depth of 20.00 mm keeps this bit in its optimal performance range for shallow-to-moderate depth holes in ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide grade KCP15B for hardness and wear resistance in steel drilling\u003c\/li\u003e\n\u003cli\u003eMultilayer AlTiN and TiN coating for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces entry thrust and improves positional accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 6.00 mm diameter fits standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eScrew machine length geometry provides rigidity for high-speed production drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for CNC and manual drilling equipment accepting a 6.00 mm straight cylindrical shank, compatible with the KENNAMETAL HPX series tooling platform in steel drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Do not exceed the maximum recommended drilling depth of 20.00 mm per pass without withdrawing to clear chips, as this bit does not have coolant-through capability. Consult applicable shop safety standards and OSHA machine guarding requirements before operating rotating tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN and TiN Multilayer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCP15B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 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: 6781153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733406679346,"sku":"6781153","price":162.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c20dc0308b642cc6303db63476dd5b8b.jpg?v=1788755277","url":"https:\/\/voomisupply.com\/products\/kennametal-6781153-drill-bit-5mm-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
