It carries a TiAlN (titanium aluminum nitride) coating that extends tool life at elevated cutting temperatures, making it well suited for dry or semi-dry machining operations. The drill features a 130-degree four-facet point geometry that improves centering accuracy and reduces walking on entry, which is critical when holding tight positional tolerances in small-diameter work. At 3.15 mm in diameter with a 56 mm overall length, this bit fits standard toolholding setups used in CNC drilling and precision machining environments. It is a right-hand cut design and ships individually as a single-piece unit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in precision machining, toolroom, and production drilling applications where small-diameter hole quality and dimensional accuracy are required. Typical applications include drilling in hardened steels, stainless alloys, cast iron, and other materials where a standard high-speed steel bit would wear prematurely. The 4.00 mm shank diameter allows it to seat in collet chucks and drill chucks sized for that shank. It is appropriate for use in CNC machining centers, CNC drill presses, and manual precision drill presses operated by machinists and toolmakers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life in dry or minimum-quantity lubrication (MQL) cutting conditions\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point geometry promotes accurate self-centering and clean entry without a center punch in many applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n  \u003cli\u003e3.15 mm cutting diameter with 18.00 mm flute length accommodates typical shallow-to-moderate depth micro drilling tasks\u003c\/li\u003e\n  \u003cli\u003e4.00 mm shank diameter fits standard collet and drill chuck toolholding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production micro drill bit for use in any toolholding system accepting a 4.00 mm shank; part of OSG Series 5330.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or changing tooling. Seat the 4.00 mm shank fully and evenly in the collet or drill chuck and verify runout before beginning a cut. Do not exceed the recommended feed and speed parameters for the workpiece material and drill diameter, as solid carbide tooling is brittle and susceptible to fracture under excessive load or lateral deflection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.15 mm (0.1240 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 56.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 18.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\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\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\u003eSeries\u003c\/strong\u003e: 5330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3300315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755317494066,"sku":"3300315","price":127.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7adcbc9e59b9737ab1b31f6a4f6c800d_58b7db18-c399-45b5-afbd-00691f4273dc.jpg?v=1788953539","url":"https:\/\/voomisupply.com\/products\/osg-3300315-micro-drill-bit-3-15-mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
