Built from high speed steel (HSS) with an oxide coating, it features a 135-degree split point and web-thinned, tapered web construction that reduces walking on entry and lowers thrust force during drilling. The 1\/4-28 threaded hex shank provides a secure, concentric connection to compatible threaded chucks or adapters. With a 1\/8 inch diameter and a compact 1 inch overall length, this bit is suited for tight-clearance drilling applications where a standard-length bit would not fit.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in hand-held or machine drilling operations on low-tensile strength materials such as aluminum, soft steel, plastics, and composites. The short overall length and 9\/16 inch flute length make it appropriate for work in confined areas or where reduced bit overhang is required for accuracy. It is typically used by machinists, HVAC technicians, electricians, and plumbers for sheet metal, panel, and bracket drilling tasks. The right-hand cutting direction and spiral flute geometry promote clean chip evacuation during through-hole drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces drill walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves cutting efficiency in low-tensile strength materials\u003c\/li\u003e\n\u003cli\u003eOxide-coated high speed steel construction for general purpose durability\u003c\/li\u003e\n\u003cli\u003e1\/4-28 threaded hex shank for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003eCompact 1 inch overall length suits tight-clearance and restricted-access drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes consistent chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with threaded shank drill chucks or adapters accepting a 1\/4-28 thread.

Ensure the threaded shank is fully engaged and torqued into the chuck or adapter before operation. Disconnect power from any motorized tool before bit changes. Select appropriate drill speed for the workpiece material to prevent overheating and premature wear of the HSS cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9\/16 inch (0.5625 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\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 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\u003eWeight\u003c\/strong\u003e: 0.15 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: 88143300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737095373106,"sku":"88143300","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec112505e66289a55a3f1c0dd9916d54.jpg?v=1788784171","url":"https:\/\/voomisupply.com\/products\/hertel-88143300-1-8-inch-threaded-shank-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
