The 135-degree split point tip reduces walking on contact and allows drilling to begin without a center punch, improving accuracy on flat and curved surfaces. A tapered web with web thinning keeps cutting resistance low throughout the stroke. The straight-cylindrical shank provides secure chuck engagement on standard 3-jaw chucks. Right-hand spiral flutes clear chips efficiently during through-hole drilling. This bit is suited for use by electricians, HVAC technicians, plumbers, and general trade professionals who need reliable small-diameter hole making in the field or shop.\u003c\/p\u003e\n\u003cp\u003eThe DW1603 is a single-piece bit with a 6 inch overall length and a 1.65 inch flute length, giving it enough reach for typical panel knockouts, pilot holes, and light structural drilling tasks. The oxide finish provides mild corrosion resistance during storage and transit. The regular spiral flute geometry works well in wood, making it a practical choice for residential and light commercial service work where a compact, reliable 1\/8 inch bit is needed on short notice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point tip reduces bit walking and eliminates the need for center punching\u003c\/li\u003e\n  \u003cli\u003eTapered web with web thinning reduces cutting resistance throughout the full flute length\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles heavy-duty drilling cycles\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with 3 flats seats securely in standard 3-jaw chucks\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides basic corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement mechanics drill bit compatible with standard 3-jaw drill chucks accepting a 1\/8 inch straight-cylindrical shank.

Ensure the workpiece is secured before drilling to prevent rotation or shifting. When drilling near electrical components or live panels, follow NFPA 70E safe work practices and de-energize circuits before making penetrations. Allow the bit to cool between extended drilling cycles to preserve temper in the high-speed steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\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\u003eOverall Length\u003c\/strong\u003e: 6 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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: DEWALT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW1603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51558235898162,"sku":"DW1603","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96e00df71f5ef88ec1f1bc0be4692fb4.jpg?v=1786406888","url":"https:\/\/voomisupply.com\/products\/dewalt-dw1603-1-8-in-hss-split-point-mechanics-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
