Built from solid carbide with a TiN tip coating, it delivers the hardness and heat resistance required for cutting stainless steel, cast iron, and high-temperature alloys. The 140-degree point angle improves centering and reduces thrust on entry. At 2.5984 inches overall length with a 5.90 mm diameter, this is a stub-length bit suited for rigid setups and short-reach applications. Coolant-through capability supports heat management during extended production runs. Licensed HVAC, machine, and tooling technicians will find this bit appropriate for precision drilling in tight tolerances.\u003c\/p\u003e\u003cp\u003eThis bit is used in CNC machining centers, drill presses, and screw machines where short overall length and rigidity are required. The 2-flute regular spiral design handles chip evacuation in ferrous and exotic alloy materials. Primary target materials include stainless steel, cast iron, and high-temperature alloys  -  common in HVAC component manufacturing, mechanical contracting, and industrial maintenance environments. The straight cylindrical shank and 6.00 mm shank diameter make it compatible with standard drill chucks and collet systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for durability in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiN tip coating reduces wear and extends tool life in stainless steel and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree point angle for improved self-centering and reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains core strength along flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in applications involving stainless steel, cast iron, and high-temperature alloys.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Carbide bits are brittle  -  avoid lateral loading, impact, or prying during use. Coolant-through setups should be verified for adequate flow before beginning production drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.90 mm (0.2323 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 20.00 mm (0.7874 inches)\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 Point Length\u003c\/strong\u003e: 0.99 mm (0.0389 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Tip)\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.049 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.5 x 0.8 x 0.8 inches\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: 4121532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739313865010,"sku":"4121532","price":124.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_99b562f8-c325-495a-bbe8-5236526a9319.jpg?v=1788813015","url":"https:\/\/voomisupply.com\/products\/kennametal-4121532-screw-machine-drill-bit-5-90mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
