Built from solid carbide with a bright\/uncoated finish, this bit measures 0.166 inches in diameter (wire size 19) with a 135-degree split point and web-thinned geometry for fast engagement and reduced thrust. The overall length is 2.125 inches with a 1.0625-inch spiral flute length. Right-hand cut with a slow spiral and straight-cylindrical shank, this bit suits CNC machining centers, drill presses, and manual setups where a compact stub-length tool is required.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and general steel stock. The screw machine length profile keeps the tool short and rigid, reducing deflection in high-precision applications such as component manufacturing, maintenance machining, and production drilling. The single-margin, slow-spiral flute design aids chip evacuation in tough, stringy materials. No coolant-through capability is present, so external coolant or cutting fluid should be applied as needed for heat management.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web-thinned tip reduces walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute promotes chip control in cast iron and stainless steel\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body at 2.125 inches overall increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids without coating interaction\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.166 inches diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit in the M.A. FORD Series 205 line, suited for wire size 19 (0.166-inch diameter) applications across drill presses, CNC machining centers, and turret lathes used in metalworking trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or maintenance technicians familiar with carbide tooling. Ensure the spindle and chuck or collet are clean and properly tightened before operation, as solid carbide is brittle and sensitive to side loading or runout. Power down and lock out the machine before changing bits. Apply cutting fluid externally to manage heat; avoid dry running in stainless steel or steel without lubrication.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 1\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0183 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: M.A. FORD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20516600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51742159831346,"sku":"20516600","price":49.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_c00a4b54-8707-4659-a9b4-e254f868c164.jpg?v=1788835668","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20516600-screw-machine-drill-bit-0-166-in","provider":"Voomi Supply","version":"1.0","type":"link"}
