Built from solid carbide with a TiN tip coating, it delivers extended tool life and heat resistance compared to standard HSS alternatives. The 140-degree split point reduces walking and entry force, making it well-suited for fast, accurate hole-starting without a center punch. Coolant-through design channels cutting fluid directly to the cutting edge, supporting chip evacuation and thermal control during deep or high-cycle drilling. Licensed machinists and tool-and-die professionals are the primary installers of this bit type.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, screw machines, and production drilling applications where short-length rigidity and tight tolerance hole quality are required. The straight shank allows direct chuck mounting in standard collet or drill chuck setups. Its compact screw machine length profile minimizes deflection and maximizes rigidity in high-feed applications. It is appropriate for drilling ferrous and non-ferrous workpiece materials in both job shop and production floor settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance over HSS\u003c\/li\u003e\n\u003cli\u003eTiN tip coating reduces friction and extends cutting edge life at the point\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle minimizes walk-on entry and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design improves chip evacuation and controls cutting heat\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, regular spiral flute, 2-flute configuration\u003c\/li\u003e\n\u003cli\u003eStraight shank for compatibility with standard collet chucks and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style production drill bit for use in screw machines and CNC drilling applications accepting straight-shank drill bits of equivalent diameter and series specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power locked out per applicable safety procedures. Secure the straight shank firmly in a properly sized collet or drill chuck to the manufacturer-specified clamping torque range for that chuck system. Verify coolant-through supply lines are connected and flow is confirmed before initiating cuts. Inspect the cutting edge for chips or wear before each production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 4151126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755505353010,"sku":"4151126","price":125.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64b4b4dc5b031e4661c0399c05bb8048_98457e5e-0cee-46f1-b2bb-ca5c85c31483.jpg?v=1788955607","url":"https:\/\/voomisupply.com\/products\/kennametal-4151126-screw-machine-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
