Built from solid carbide and coated with TiN at the tip, this bit delivers extended tool life and reduced friction at the cutting edge. It carries a wire gauge size of 7, equivalent to 0.2010 inches in decimal, and features a 140-degree split point angle for accurate self-starting on entry. With a 2-flute regular spiral configuration and coolant-through capability, it supports higher feed rates and effective chip evacuation in production environments. Licensed machinists and CNC operators are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for short-hole drilling operations in ferrous and non-ferrous metals where a compact, stub-length tool is required. The screw machine length profile offers greater rigidity than jobber-length bits, making it well suited for drill press, CNC machining center, and turret lathe applications. The coolant-through design supports internal coolant delivery for deep-feature work within its maximum drilling depth of 20.00 mm. The straight cylindrical shank, measuring 6.00 mm in diameter, seats directly into standard collets and drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiN tip coating for extended cutting life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle for fast, accurate entry with minimal walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery during drilling\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides added rigidity versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit in Series B051CPG, compatible with standard straight-shank tool holders, collets, and drill chucks accepting a 6.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine fully powered down and at a complete stop before removing or seating the bit. Secure the shank firmly in the collet or chuck to the manufacturer-specified clamping depth before operation. Verify coolant-through passages are clear before enabling internal coolant flow. Handle solid carbide tooling carefully to avoid chipping the cutting edges during storage and setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\u003c\/li\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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 Length\u003c\/strong\u003e: 28.00 mm\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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 Length\u003c\/strong\u003e: 0.85 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3.5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 4151136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728051634482,"sku":"4151136","price":125.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a8e2c02be1e4da2bcb4f685dc5d7cb7.jpg?v=1788687082","url":"https:\/\/voomisupply.com\/products\/kennametal-4151136-screw-machine-drill-bit-size-7-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
