Built from cobalt tool material, it handles cast iron, steel, alloy steel, and carbon steel without the heat buildup that degrades standard high-speed steel bits. The bit measures 0.5 inches in diameter with a matching 0.5-inch straight-cylindrical shank, an overall length of 6 inches, and a 3.125-inch flute length. The 118-degree split point starts on contact and reduces walking without a center punch on most workpieces. This bit is sold individually and suits machinists, pipefitters, ironworkers, and HVAC and plumbing technicians who drill through ferrous materials in the field.\u003c\/p\u003e\u003cp\u003eThe 53432 fits portable drill applications where a reduced shank is required to chuck a 0.5-inch diameter bit in a standard 3\/8-inch or smaller chuck. Primary workpiece materials are cast iron and steel. Secondary materials include alloy steel, carbon steel, and cast iron. The Series 190C designation places it in a consistent production line, making replacement and reorder straightforward for shops that stock by series. The right-hand cutting direction is standard for conventional drilling setups. No coolant supply is required for general-purpose use, though flood or mist coolant can extend tool life in sustained production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material resists heat and wear when drilling cast iron and steel\u003c\/li\u003e\n\u003cli\u003e118-degree split point reduces thrust and prevents bit walking on contact\u003c\/li\u003e\n\u003cli\u003eReduced shank allows a 0.5-inch diameter bit to fit smaller chuck capacities\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank provides secure grip in standard drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes with regular helix evacuate chips efficiently during through-hole drilling\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches ensures consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for portable drilling of cast iron, steel, alloy steel, and carbon steel workpieces.

Wear appropriate eye protection and secure the workpiece to prevent rotation during drilling. For best results in hard ferrous materials, use cutting fluid and moderate feed pressure to avoid overheating the cutting edges. Inspect the split point for chipping or wear before reuse; a damaged point increases thrust and reduces hole accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\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: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 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: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728826892594,"sku":"53432","price":63.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcf0b354dee8f39cd6e5bd3ddab3de7d.jpg?v=1788696457","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53432-cobalt-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
