Ground from vanadium high speed steel with a multi-layer coating, this bit is built to handle demanding materials including steel, alloy steel, aluminum, and aluminum silicate. The 140-degree faceted point reduces thrust and improves self-centering on entry. At 0.0550 inches (No. 54 wire gauge) in diameter and 1.6142 inches overall length, it fits compact, tight-tolerance drilling setups where standard jobber-length bits are too long. The straight cylindrical shank seats cleanly in drill chucks and quick-change holders.\u003c\/p\u003e\u003cp\u003eThis bit is designed for use in screw machine operations, CNC drilling centers, turret lathes, and other production drilling environments where short-length geometry provides better rigidity and reduced deflection. With a 3xD flute-to-diameter ratio, it clears chips efficiently in shallow-to-medium-depth holes. Machinists, tool-and-die makers, and production drilling technicians working in job shops, manufacturing facilities, and aerospace component work will find this bit suited to precision hole-making in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 54 wire gauge diameter — 0.0550 inches — for tight-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e140-degree faceted split point reduces walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eVanadium high speed steel construction with multi-layer finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body improves rigidity and minimizes deflection in production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with web-thinned tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Ensure the spindle is fully stopped and the machine is powered down before changing or inspecting tooling. Secure the shank fully within the chuck or collet to the manufacturer-recommended grip depth to prevent pullout under load. Always verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.6142 inches (41.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 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\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine (Stub)\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\u003eTool Material\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Multi-Layer Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 11509115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733829452082,"sku":"11509115","price":36.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/294a9a22803f10164390c64ba2c5d9de.jpg?v=1788759501","url":"https:\/\/voomisupply.com\/products\/osg-11509115-screw-machine-drill-bit-54-wire-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
