Built from high speed steel with an oxide finish, this bit offers a 1.25-inch diameter and a compact overall length of 6.75 inches, making it well-suited for work in tighter setups where a jobber-length bit would be unwieldy. The 118-degree standard point angle provides reliable centering on flat and curved surfaces. With two spiral flutes and a 3xD flute-to-diameter ratio, chip evacuation is efficient during moderate-depth holes. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles.\u003c\/p\u003e\u003cp\u003eThis bit is intended for general-purpose drilling in production and maintenance environments. Screw machine length bits are commonly specified when rigidity and reduced deflection matter more than extended reach. Typical applications include metal fabrication shops, machine shops, and maintenance operations where consistent, repeatable hole quality in steel and similar materials is required. The ANSI-specification designation confirms dimensional conformance to standard tooling systems. This bit is sold individually and carries no coolant-through capability, making it best suited for conventional drilling with standard cutting fluids applied externally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25-inch diameter with 4.375-inch flute length for controlled cutting depth\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e118-degree standard drill point for reliable starting on flat and round surfaces\u003c\/li\u003e\n\u003cli\u003eTwo regular spiral flutes promote chip clearance during drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and machine spindles\u003c\/li\u003e\n\u003cli\u003eANSI specification designation ensures dimensional compliance with standard tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose drill bit compatible with standard drill chucks and machine spindles accepting a straight-cylindrical shank in the 1.25-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician. Secure the straight-cylindrical shank fully in the drill chuck before operation and verify runout before cutting. Apply an appropriate cutting fluid externally, as this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 61698437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732420362546,"sku":"61698437","price":211.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e34948515a132ddea86c75b2ac2be80_3ffb1756-ee17-4e93-96eb-153671f8e29d.jpg?v=1788742604","url":"https:\/\/voomisupply.com\/products\/hertel-61698437-screw-machine-drill-bit-1-25-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
