Built from solid carbide and coated with TiAlN (tip), this bit delivers hardness and heat resistance suited to high-speed drilling in ferrous and non-ferrous materials. It carries a wire gauge size of 36, equivalent to 0.1065 inches in decimal, and features a 140-degree standard point angle for aggressive, self-centering entry. The two-flute, regular spiral design promotes efficient chip evacuation during drilling cycles. Overall length is 2.2835 inches, with a straight cylindrical shank measuring 0.1575 inches in diameter. Licensed machinists and tool-and-die technicians are the primary installers of this type of bit.\u003c\/p\u003e\u003cp\u003eThis bit is suited to CNC machining centers, drill presses, and screw machine setups where tight-tolerance, small-diameter hole generation is required. The stub flute length of 0.6693 inches keeps the bit rigid, reducing deflection in short-depth applications. Maximum drilling depth is 0.4724 inches, making it appropriate for shallow, precision holes in production environments. The tapered web configuration adds strength at the tip and supports consistent performance across repeated operations. The DIN 6537K specification designation confirms dimensional conformance to recognized standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding machining operations\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating provides thermal protection and extended tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length design minimizes deflection and improves hole accuracy in short-depth drilling\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds tip strength for repeatable, high-cycle performance\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard straight-shank drill chucks and collets accepting a 0.1575-inch shank diameter, in CNC machining centers, turret lathes, and bench drill presses requiring wire gauge size 36 tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by a qualified machinist or tooling technician. Secure the straight cylindrical shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle completely before changing tooling. Do not exceed the manufacturer-recommended feed and speed parameters for carbide tooling in the material being drilled, as carbide is brittle and susceptible to fracture from excessive side-loading or interrupted cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1065 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: TiAlN (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: 0.6693 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2835 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: 0.1575 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0171 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B041A-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: 4151655\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750439551282,"sku":"4151655","price":94.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6564efa05857da587c3105a4300d12ec.jpg?v=1788915504","url":"https:\/\/voomisupply.com\/products\/kennametal-4151655-drill-bit-size-36-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
