Built to material grade KCMS15 and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures without sacrificing edge integrity. The 140-degree split-point geometry reduces thrust and self-centers on entry, minimizing the need for a center punch in most setups. At 2.9134 inches overall length with a 1.4173-inch flute length, this is a compact, rigid tool suited for precision hole-making. It features a straight cylindrical shank, right-hand cut, and two regular spiral flutes. Coolant-through capability supports chip evacuation in deep or interrupted cuts.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for stainless steel and high-temperature alloy applications where standard HSS tooling fails prematurely. The AlTiN coating extends tool life in dry or minimum-quantity lubrication (MQL) conditions. The 5xD flute-to-diameter ratio and 29.00 mm maximum drilling depth make it appropriate for through-holes and blind holes in tight-tolerance machining operations. It is commonly used in aerospace, petrochemical, and industrial fabrication environments where material hardness and work-hardening are primary concerns. Both CNC machining centers and manual drill press setups can run this bit when proper speeds and feeds are applied.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at KCMS15 material grade for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal protection and oxidation resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle for reduced entry thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing in deep-hole and high-feed applications\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute regular spiral configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with 6 mm shank diameter fits standard collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling stainless steel and high-temperature alloys.

Secure the shank fully in a collet or drill chuck rated for the shank diameter before running the spindle. Always verify recommended speeds and feeds for the target material before cutting, as solid carbide tooling is brittle and susceptible to breakage from excessive lateral load or improper feed rate. Engage coolant-through supply where available to maximize chip clearance and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCMS15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9134 inches (74.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1417 inches (29.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0224 inches (0.57 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.95 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0395 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6350389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741263298866,"sku":"6350389","price":288.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccc4eb574fb7b8e724fde9bf5fb93fd3_9ecfa6fb-0142-4e94-a66b-9bd5d241fc07.jpg?v=1788830392","url":"https:\/\/voomisupply.com\/products\/kennametal-6350389-jobber-drill-bit-0-1520-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
