It carries a No. 33 wire gauge designation, corresponding to a decimal diameter of 0.1130 inches. The 180-degree flat-bottom point geometry eliminates the angled tip common to standard twist drills, producing a true flat-bottomed hole with minimal breakthrough burr. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in harder workpiece materials. The overall length is 63 millimeters, with a spiral flute configuration for efficient chip evacuation. Right-hand cutting direction is standard. This drill is part of the Harvey Tool Miniature High Performance Drills - Flat Bottom Drill series.\u003c\/p\u003e\n\u003cp\u003eThis tool is suited for precision machining operations where flat-bottom bores are required, such as counterbores, blind holes, and stepped bore features. Typical applications include mold and die work, aerospace component machining, medical device manufacturing, and high-tolerance fixture fabrication. The h6 diameter tolerance on the drill body supports use in close-tolerance setups. It is installed in CNC machining centers, drill presses, and precision manual mills by machinists and toolmakers working in job shop or production environments. The 4.00 millimeter shank diameter is compatible with standard collet systems sized for metric shanks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180-degree flat-bottom point produces true flat-bottomed blind holes without a center tip\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry promotes chip evacuation in deep or blind hole drilling\u003c\/li\u003e\n  \u003cli\u003eh6 shank diameter tolerance ensures consistent collet grip and runout control\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and precision drilling setups equipped with collet toolholding systems that accept a 4.00 millimeter metric shank diameter.

Seat the shank fully and evenly in a clean, undamaged collet before torquing the collet nut to the toolholder specification. Confirm spindle runout with a test indicator before initiating a cut, as runout is especially critical at small diameters. Do not use this drill in impact-type or hammer drill drivers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 33\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees (Flat Bottom)\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7480 inches (19.00 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.03 inches L x 0.32 inches W x 0.32 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FBD1130-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51753060303154,"sku":"FBD1130-C3","price":121.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15b9d646d7e7077302d9b595b3bc8461_4f386640-f66d-414e-a476-cd136a7378b3.jpg?v=1788932519","url":"https:\/\/voomisupply.com\/products\/harvey-tool-fbd1130-c3-micro-drill-bit-no-33-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
