The bit measures 20 mm in diameter (0.7874 decimal inch) with a 153 mm overall length and a 101 mm flute length. A 140-degree split point geometry reduces walking and thrust load on entry. The TiAlN (titanium aluminum nitride) coating provides thermal resistance and extended tool life at elevated cutting speeds. Coolant-through capability supports through-tool coolant delivery for chip evacuation and heat control in deep-hole drilling operations. Installed by machinists and tool-and-die professionals in CNC machining centers and manual drill presses.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for production drilling in ferrous and non-ferrous metals, alloy steels, stainless steels, and cast iron. The R-thinned web reduces cutting resistance at the chisel edge, which is especially useful in harder workpiece materials. With a 5xD flute-to-diameter ratio and straight cylindrical shank, this bit fits standard ER collet chucks and drill chucks across a wide range of machining equipment. It is dimensioned to DIN specification standards, making it a direct fit in shops that source to metric tooling standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in demanding cutting conditions\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life and supports dry or minimum-quantity lubrication cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point reduces entry thrust and material deformation\u003c\/li\u003e\n  \u003cli\u003eR-thinned web lowers chisel-edge cutting resistance for cleaner hole initiation\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design enables through-tool coolant delivery for deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eDIN specification designation ensures dimensional interchangeability with metric tooling standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses accepting a 20 mm straight cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight shank fully and concentrically in the collet or drill chuck and torque the retention mechanism to the machine manufacturer specification. Verify coolant-through passages are clear and aligned before running coolant-enabled operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 20 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 153 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 101 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\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: Regular 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: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743134941490,"sku":"4500201","price":588.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5a470d1258ab7a501aadb93c1779e69_12b3f045-2f71-4073-8ee6-b38a578ddac3.jpg?v=1788843088","url":"https:\/\/voomisupply.com\/products\/accupro-4500201-solid-carbide-jobber-drill-20mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
