It features a 19\/32 inch (0.5938 inch decimal) cutting diameter paired with a 1\/2 inch straight-cylindrical shank, allowing it to be chucked in standard 1\/2 inch drill chucks even at larger bit diameters. The 118 degree standard point angle suits a broad range of materials and is the industry-standard geometry for general shop and field work. Overall length is 6 inches with a 3 inch flute length, giving adequate depth capacity for most through-hole and blind-hole applications.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in stationary drill presses, magnetic base drills, and hand-held power drills equipped with a 1\/2 inch chuck. The reduced shank design makes it practical for tradespeople and machinists who need larger diameter holes without upgrading to a larger chuck. Typical applications include metalwork in mechanical, HVAC, plumbing, and electrical trades where holes in steel plate, sheet metal, aluminum framing, copper pipe flanges, and structural members are required. The right-hand spiral flute geometry promotes smooth chip evacuation in both ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e19\/32 inch cutting diameter with 1\/2 inch reduced shank fits standard 1\/2 inch chucks\u003c\/li\u003e\n\u003cli\u003e118 degree standard point angle for general-purpose use across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel (HSS) construction provides toughness and heat resistance for production drilling\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 3 inch flute length supports deeper hole drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating buildup to affect tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for reliable chip clearing\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series R56\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with any 1\/2 inch keyed or keyless drill chuck.

Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before operation. Coolant is not required for this bit, but cutting fluid may be applied to extend tool life when drilling harder ferrous materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/32 inches (0.5938 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Cermet, Copper, Magnesium, Nickel, Synthetic, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51716135190834,"sku":"5999956","price":61.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a840ba4b67dd7be5c7602119fb25fb82.jpg?v=1788522247","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999956-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
