Built from cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, this bit handles demanding production environments where standard HSS tooling wears prematurely. Wire size 7 corresponds to a decimal diameter of 0.2010 inches (5.11 mm). The 130-degree split point angle promotes self-centering and reduces walking on entry. A tapered web with R-thinning reduces thrust force and improves chip clearance. Overall length is 4-1\/4 inches with a 2-7\/16-inch flute length, making it compatible with standard drill chucks and quick-change systems that accept a 1\/4-inch straight-cylindrical shank.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machinists, maintenance mechanics, and fabricators working in job shop or production environments. Typical applications include blind hole drilling, cross-hole drilling, and through-hole work in mild steel, alloy steel, and similar ferrous materials. The regular spiral flute geometry provides efficient chip evacuation in both hand-held and machine-mounted operations. It belongs to OSG Series 1500, a line intended for general-purpose to high-performance drilling in metalworking trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for elevated heat resistance compared to standard HSS bits\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction in ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with R-thinned web for self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute spiral geometry for effective chip removal\u003c\/li\u003e\n\u003cli\u003e1\/4-inch straight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, drilling, and self-centering tool applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel and alloy steel workpieces as indicated by Primary Workpiece Material Code P.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Do not exceed recommended RPM for the diameter and material combination. When replacing a worn bit, inspect the chuck or collet for wear that could cause slippage or premature tool failure.\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\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 5.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches (107 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches (61 mm)\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: Spiral, Regular\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: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15201005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732549796146,"sku":"15201005","price":49.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3a79f6ba9d966e078134db520a7bb6d.jpg?v=1788744343","url":"https:\/\/voomisupply.com\/products\/osg-15201005-cobalt-jobber-drill-bit-wire-size-7-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
