{"product_id":"bordo-1-1-4-reduced-1-2-shank-drill","title":"Bordo HSS 1-1\/4\" Reduced 1\/2\" Straight Shank Drill Bit","description":"\u003cp\u003eThis Bordo reduced shank drill features a 118° notched point with a 30° helix. The notched point is a variation of the standard chisel point, designed to provide faster starting, reduced drill wander, and improved accuracy. A 118° point angle is ideal for materials such as mild steel and cast iron, producing easily controlled chips that are wide and thin.\u003c\/p\u003e\n\u003cp\u003eBordo reduced shank HSS drills are precision ground, then steam tempered to create a durable black oxide surface. This porous finish enhances lubrication, chip flow, and heat dissipation during drilling. Finally, the drill is ground a second time to produce bright, sharp cutting edges and a smooth shank finish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features \u0026amp; Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1-1\/4\" diameter with reduced 1\/2\" shank for use in standard drill chucks\u003c\/li\u003e\n\u003cli\u003e118° notched point for improved starting accuracy and reduced wander\u003c\/li\u003e\n\u003cli\u003e30° helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSteam tempered black oxide finish improves heat dissipation and chip flow\u003c\/li\u003e\n\u003cli\u003ePrecision ground HSS construction for long tool life\u003c\/li\u003e\n\u003cli\u003eIdeal for drilling mild steel, cast iron, and similar materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDiameter (inch): 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003eDiameter (mm): 31.75 mm\u003c\/li\u003e\n\u003cli\u003eFlute Length: 86 mm\u003c\/li\u003e\n\u003cli\u003eOverall Length: 152 mm\u003c\/li\u003e\n\u003cli\u003eShank Size: 1\/2\"\u003c\/li\u003e\n\u003cli\u003ePoint Angle: 118°\u003c\/li\u003e\n\u003cli\u003eHelix Angle: 30°\u003c\/li\u003e\n\u003cli\u003eMaterial: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003eFinish: Steam tempered black oxide with bright-ground cutting edges\u003c\/li\u003e\n\u003cli\u003eFeed per Revolution: 0.5 mm\u003c\/li\u003e\n\u003cli\u003eRecommended Spindle Speeds:\n\u003cul\u003e\n\u003cli\u003eAluminium\/Brass: 612 RPM\u003c\/li\u003e\n\u003cli\u003eCast Iron: 241 RPM\u003c\/li\u003e\n\u003cli\u003eFree Cutting Steel: 431 RPM\u003c\/li\u003e\n\u003cli\u003eMalleable Iron: 271 RPM\u003c\/li\u003e\n\u003cli\u003eMedium Carbon Steel: 301 RPM\u003c\/li\u003e\n\u003cli\u003eStainless Steel: 120 RPM\u003c\/li\u003e\n\u003cli\u003eTool Steel: 181 RPM\u003c\/li\u003e\n\u003cli\u003eWood\/Plastic: 913 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis reduced shank drill is designed for applications where large diameter drilling is required using a standard 1\/2\" chuck, offering versatility, durability, and excellent performance across a wide range of materials.\u003c\/p\u003e","brand":"BORDO","offers":[{"title":"Default Title","offer_id":52538581942559,"sku":"2651-1.1\/4","price":210.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/2484\/1799\/files\/bordo-drills-bordo-hss-1-1-4-reduced-1-2-straight-shank-drill-bit-9326518004455-1238186447.webp?v=1778821057","url":"https:\/\/twineagleimports.com\/products\/bordo-1-1-4-reduced-1-2-shank-drill","provider":"Twin Eagle Imports ","version":"1.0","type":"link"}
