Built from high speed steel (HSS) with an oxide coating, this bit meets NAS 965 Type B specification and is sized to wire gauge No. 40 (0.0980 inches decimal equivalent). The 135-degree split point geometry reduces walking on entry and lowers thrust force during penetration. The web-thinned, tapered web construction improves chip evacuation and cutting efficiency. At 1.0 inch overall length with a 9\/16-inch flute length, this is a compact bit suited for tight-access drilling applications. The 1\/4-28 threaded hex shank provides positive retention in compatible quick-change chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in light-gauge metals, plastics, and other low-tensile strength materials commonly encountered in HVAC, electrical, and plumbing trade work. The compact 1.0-inch overall length makes it well suited for drilling in confined spaces — equipment cabinets, junction boxes, panel enclosures, and structural members where clearance is limited. Right-hand cutting direction and regular spiral flutes make this a standard-use bit for production drilling or service work requiring consistent, repeatable hole sizing at the No. 40 wire gauge diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 40 size — 0.0980 inch decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walk and lowers drilling thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip clearance and cutting performance\u003c\/li\u003e\n  \u003cli\u003eOxide-coated high speed steel construction for durability in general-purpose applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 threaded hex shank for use with compatible quick-change chuck systems\u003c\/li\u003e\n  \u003cli\u003eNAS 965 Type B specification compliance for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with quick-change drill systems and tool holders accepting a 1\/4-28 threaded hex shank.

Confirm the 1\/4-28 threaded shank is fully seated and locked in the chuck before operation. Use appropriate cutting speed for the material being drilled — excessive speed in metal applications accelerates edge wear on HSS tooling. Eye protection and gloves are standard PPE when operating any rotary cutting tool.\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: No. 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0980 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\u003eOverall Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Hex Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Thread Size\u003c\/strong\u003e: 1\/4-28\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eMaterial Application\u003c\/strong\u003e: Low-Tensile Strength Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 965 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: 0.15 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08512220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735010246962,"sku":"08512220","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5264ee68e4340dd91b38855604f580bf.jpg?v=1788769170","url":"https:\/\/voomisupply.com\/products\/hertel-08512220-no-40-drill-bit-135-split-point-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
