Built from high speed steel with an oxide coating, it is engineered for heavy-duty drilling in demanding materials including cast iron, stainless steel, and carbon steel. The 135-degree split point reduces walking on contact and requires no center punch on most surfaces. With a regular spiral flute and right-hand cut geometry, the 45701 is a reliable production-floor and service-truck staple for machinists, pipefitters, and maintenance technicians who drill small-diameter holes at high cycle rates.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use in hand drills, drill presses, and CNC drilling operations where wire gauge tooling is required. The straight-cylindrical shank fits standard chucks without adapters. The web-thinned, tapered web construction reduces thrust load, which is especially valuable when working through stainless steel or dense cast iron. At 2.75 inches overall length with a 1.625-inch flute, the 45701 offers standard jobber reach appropriate for most through-hole and moderate-depth applications in fabrication, HVAC equipment manufacturing, and mechanical service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 31, 0.1200-inch diameter with a tight tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for reduced walking and lower entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling force in hard materials\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification for high-performance heavy-duty drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron, stainless steel, and steel workpieces.

Machinists and maintenance technicians should verify spindle speed is appropriate for 0.1200-inch HSS tooling in the target material before drilling. Apply cutting fluid when drilling stainless steel or cast iron to extend tool life and manage heat buildup. Inspect the split point for chipping before each use; a damaged point will affect hole accuracy and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1200 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\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0075 pounds\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727810298162,"sku":"45701","price":35.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/782460eef0061e5342807dea23a26913_74b6eb46-d85c-4e1d-b059-1fb8b66069c0.jpg?v=1788682796","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45701-jobber-drill-bit-31-hss-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
