Built from high-speed steel with an oxide coating, it features a 135-degree split point that reduces walking and lowers thrust requirements at entry. The web-thinned, parallel-web construction supports heavier feeds without sacrificing edge stability. At 3.25 inches overall length, the stub-length format delivers added rigidity over jobber-length bits, making it well-suited for drill press and CNC turret applications where chatter and deflection need to be minimized.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in screw machine operations, production drilling fixtures, and general metalworking setups requiring a stub-length drill in the 0.35 to 0.40 inch size range. The straight cylindrical shank fits standard drill chucks and collet holders without modification. The right-hand spiral flute geometry promotes chip evacuation during through-hole and blind-hole drilling in steel, cast iron, and similar ferrous materials. It carries NAS 907 specification under the NAS designation, indicating conformance to aerospace and industrial tooling standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter V size: 0.3770 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry thrust and eliminates pilot-punch requirements on most metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design supports heavy-duty feed rates\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide coating for wear resistance and chip adhesion reduction\u003c\/li\u003e\n\u003cli\u003eStub screw machine length (3.25 inches OAL) provides rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 specification for consistent dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for screw machine operations, CNC turrets, and drill press applications requiring a straight-shank stub-length drill bit in the 0.35 to 0.40 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing bits. Verify chuck or collet size matches the 0.3770-inch straight cylindrical shank before seating. Inspect the split point for chips or edge damage prior to use, and confirm workpiece is securely fixtured to prevent movement during drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3770 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\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: Oxide\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\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\u003eSpecification Number\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 83238915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730936398130,"sku":"83238915","price":15.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c67d9bcb577d5425a919dc7e0c40b3a2.jpg?v=1788725027","url":"https:\/\/voomisupply.com\/products\/hertel-83238915-letter-v-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
