Built from solid carbide with a coated finish, it delivers the hardness and wear resistance needed for high-cycle production drilling. The bit measures 0.315 inches in diameter with a 135-degree split point that reduces walking on entry and minimizes thrust load. Overall length is 2.7953 inches, making it a compact, rigid tool suited for CNC machining centers, drill presses, and screw machines where tool stick-out must be kept short. It is installed and used by machinists and manufacturing maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is a strong fit for production shops working with ferrous and non-ferrous stock, including stainless steel and cast iron components. The screw machine length body provides enhanced rigidity compared to jobber-length bits, reducing deflection on interrupted cuts and in cross-drilled hole applications. It carries a Series 205 designation and a flute-to-diameter ratio of 3xD, which suits shallow-to-moderate depth holes in tight-tolerance work. The right-hand cut and slow spiral flute geometry help control chip evacuation in materials that generate long, stringy chips.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for a center punch on most surfaces\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body maximizes rigidity and minimizes deflection in short-depth drilling applications\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute geometry with web-thinned parallel web improves chip flow in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life by reducing friction and heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, manual drill presses, and screw machines with standard straight-shank tool holding.

Solid carbide tooling is brittle and should be seated firmly and concentrically in the chuck or collet to prevent runout-induced chipping. Confirm correct spindle speed and feed rate for the workpiece material before beginning the cut. Do not use coolant-through fixtures, as this bit does not support coolant through the body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7953 inches (71.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.634 inches (41.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1614 inches (29.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Coated\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: Parallel 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 20531500T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743410290994,"sku":"20531500T","price":130.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_70aaed2d-f6d9-400f-8f72-b86003471dab.jpg?v=1788846746","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20531500t-screw-machine-drill-bit-0-315-in","provider":"Voomi Supply","version":"1.0","type":"link"}
