It carries a Size 30 wire gauge designation, equivalent to 0.1285 inches in diameter, with a 140-degree point angle for aggressive, accurate entry into ferrous and non-ferrous materials. The bit features a multilayer TiAlN coating at the tip to extend tool life under high-heat cutting conditions. With an overall length of 2.4409 inches and a stub flute configuration, this drill is built for rigidity and minimal deflection. Licensed machinists, tool-and-die technicians, and CNC operators are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for short-depth hole applications in production machining, screw machine operations, and CNC drilling centers. The stub length design limits overhang and maximizes stiffness, making it well-suited for high-cycle operations where hole location accuracy is critical. With coolant-through capability, it supports through-spindle coolant delivery to flush chips and manage heat at the cutting zone. Maximum drilling depth is 0.5512 inches (14.00 mm), making it appropriate for shallow through-holes and blind holes in tight tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating reduces thermal wear and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle promotes self-centering entry and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.2362 inches diameter fits standard collet and drill chuck toolholders\u003c\/li\u003e\n\u003cli\u003eTapered web configuration improves chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for CNC machining centers, manual drill presses, and screw machines requiring a Size 30 wire gauge carbide drill with a straight shank.

Ensure spindle power is off and the machine is in a safe lockout state before changing tooling. Seat the straight shank fully into the collet or drill chuck and verify runout before beginning a cutting cycle. Do not exceed the rated maximum drilling depth of 0.5512 inches per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches (62.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 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: 0.0208 inches (0.53 mm)\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: TiAlN (Tip)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\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: 4151105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743247696178,"sku":"4151105","price":124.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e550960520b5c2199cdec25f096f6e4.jpg?v=1788844480","url":"https:\/\/voomisupply.com\/products\/kennametal-4151105-size-30-carbide-drill-bit-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
