It features a 0.55 mm diameter (0.0217 inches), a 130-degree four-facet point, and a regular spiral with a 30-degree helix angle. The tapered web configuration and right-hand cut geometry provide accurate entry and chip evacuation in small-diameter work. At 1.5 inches overall length with a 1\/8 inch shank, this bit is sized for use in CNC drilling machines and precision drill presses common in electronics manufacturing and PCB fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling through a wide range of materials encountered in circuit board and precision machining work, including fiber-reinforced polymers, plastics, aluminum, copper alloy, stainless steel, cobalt alloy, nickel, titanium, and cast iron. It is appropriate for both production and prototype environments where consistent hole quality and tight diameter tolerances are required. The heavy-duty grade construction makes it a reliable choice for repetitive drilling cycles in light manufacturing and electronics assembly shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003e0.55 mm diameter with a diameter tolerance of -0.0003 to +0.0000 inches for tight hole accuracy\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point for precise entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with regular spiral and tapered web for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard PCB drill chucks and precision collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC circuit board drilling machines and precision drill presses accepting a 1\/8 inch (3.18 mm) shank.

Ensure the machine spindle and collet are clean and properly torqued before seating the shank, as carbide bits are brittle and susceptible to breakage from lateral loading or runout. Power down and de-energize the machine before changing tooling. Follow the machine manufacturer's recommended feed and speed parameters for the specific workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.55 mm (0.0217 inches)\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: Four Facet\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.34 inches (8.64 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (3.18 mm)\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07235\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51786643407154,"sku":"07235","price":16.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19052ec8be4e4838d085f6de6357f604.jpg?v=1789204850","url":"https:\/\/voomisupply.com\/products\/sgs-07235-circuit-board-drill-bit-0-55-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
