Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life and heat resistance at elevated cutting speeds. The 140-degree split point reduces walking and minimizes the need for a center punch on flat or curved surfaces. At 2.6 inches overall length with a 5.40 mm diameter and a straight cylindrical shank, it is sized for short-reach, rigid setups in CNC machining centers, drill presses, and screw machines. Coolant-through capability supports chip evacuation and thermal control in deep-hole applications. Licensed machinists and tooling specialists are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production environments requiring repeatable hole quality in steel, stainless steel, cast iron, and similar ferrous materials. The screw machine length format provides added rigidity compared to jobber-length bits, making it a preferred choice for high-cycle, tight-tolerance drilling on CNC lathes, turret presses, and automatic screw machines. The 3xD flute-by-diameter ratio supports drilling to a maximum depth of 0.79 inches (20.00 mm) per pass. It is part of the KENNAMETAL B051A-CPG series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating provides heat resistance and extends cutting life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and minimizes drill walk on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and temperature control in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard ER and drill chuck toolholders\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds core strength without sacrificing chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the KENNAMETAL B051A-CPG series.

Confirm toolholder bore and collet size accommodate the 6.00 mm straight shank before seating the bit. Do not exceed the rated maximum drilling depth of 20.00 mm per pass without retracting to clear chips. Inspect the cutting edge and coating condition before each use to identify wear or chipping that could affect hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.40 mm (0.2126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.60 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.10 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 (1.42 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 20.00 mm (0.79 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: 0.90 mm (0.0354 inches)\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: TiAlN Multilayer (TiN Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 4151140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731222462770,"sku":"4151140","price":125.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f5092dfbf09f034dd8862ac0c477fb4.jpg?v=1788728523","url":"https:\/\/voomisupply.com\/products\/kennametal-4151140-drill-bit-5-40mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
