Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this bit offers improved wear resistance and extended tool life compared to uncoated HSS. The 130-degree split point reduces walking on entry and minimizes the need for a center punch. A parabolic flute geometry improves chip evacuation, especially in deeper holes. At 2.85 mm in diameter and 2-13\/32 inches overall length, this bit suits benchtop drill presses, CNC drilling operations, and handheld power tools used in machine shops, fabrication, and light manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in aluminum and non-ferrous materials, as indicated by workpiece material codes K, N, and P. The parabolic flute with a 5xD flute-to-diameter ratio supports efficient chip clearing in through-hole and blind-hole applications. Web thinning at the point reduces thrust requirements, making it well suited for production drilling where feed rates and cycle times matter. It meets DIN 338 standards, which govern jobber-length drill geometry and tolerances. The straight-cylindrical shank is compatible with standard drill chucks across most drill press and CNC spindle configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.85 mm diameter with 0.1122 decimal inch equivalent and a diameter tolerance of -0.014 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life in production runs\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design with tapered web geometry promotes fast, clean chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute configuration suitable for standard CNC and manual drilling setups\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for jobber-length drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber-length drill bit compatible with standard straight-shank drill chucks.

Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. For optimal performance and bit longevity, use appropriate cutting fluid or coolant when drilling metals, even though this bit does not feature internal coolant-through capability. Inspect the cutting edge and TiN coating condition regularly, and replace the bit when the coating shows significant wear or the point geometry deteriorates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.85 mm (0.1122 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1300 inches (28.73 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1122 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (K, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 652\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9006520028500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748817764658,"sku":"9006520028500","price":31.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ac09ad6602a1adf74db59d20a4a6ef_c7954664-28f3-4280-9e2b-308340be9c60.jpg?v=1788898923","url":"https:\/\/voomisupply.com\/products\/guhring-9006520028500-jobber-drill-bit-2-85mm-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
