It measures 5\/8 inch (0.6250 inch) in diameter with a 130-degree split point that reduces walking and improves hole entry. The two-flute, web-thinned geometry lowers thrust requirements and supports cleaner chip evacuation. Coolant-through capability via round coolant holes allows internal coolant delivery directly to the cutting zone, extending tool life in production environments. The bright\/uncoated finish suits applications where coating interaction with workpiece material is a concern. This bit is installed by machinists and tool-room professionals on CNC machining centers, drill presses, and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 1201055 targets precision machining operations on cast iron components and non-ferrous metal workpieces such as aluminum, brass, and copper alloys. It fits production drilling scenarios where tight diameter tolerances are required, with a diameter tolerance held to +0.0000 to +0.0005 inch. The Series K411 designation places it within Kennametal's long-series carbide drill line, conforming to DIN 6537L standards. Maximum drilling depth is 2.54 inches, with a 3.25-inch flute length and a shank length of 1.909 inches providing adequate clearance for that depth range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces drill walk and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry decreases cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with round coolant holes delivers coolant directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a wide range of non-ferrous and ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance (+0.0000 to +0.0005 inch) suits close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and non-ferrous metal applications per Series K411 \/ DIN 6537L specification.

Secure the shank fully in a precision collet or drill chuck rated for the spindle speed being used, and verify tool runout before cutting. Power down and lock out the machine before changing tooling. Avoid side-loading straight-flute carbide drills, as carbide is brittle and susceptible to chipping under lateral forces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 15.88 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\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.2360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.909 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.54 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant-Hole Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to +0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: K411\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Standard\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5878 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1201055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731102007602,"sku":"1201055","price":674.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/910215cbc8f62ee274e32801854d9e93_31e17402-44e9-4c67-adc6-ecca115c8ad8.jpg?v=1788726979","url":"https:\/\/voomisupply.com\/products\/kennametal-1201055-straight-flute-drill-bit-5-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
