It features a No. 75 wire gauge size with a decimal diameter of 0.0210 inches (0.53 mm), a 130-degree four-facet point, and a regular spiral with a 30-degree helix angle. The uncoated solid carbide construction delivers the rigidity and edge retention required when drilling small-diameter holes through dense or abrasive substrates. A tapered web configuration supports chip evacuation and reduces thrust. Licensed electricians, PCB technicians, and precision machinists are the primary installers of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC drill presses, micro-drilling machines, and bench-top precision drilling equipment. It handles a wide range of workpiece materials including aluminum, cast iron, copper alloy, stainless steel, titanium, cobalt alloy, nickel, plastics, and fiber-reinforced polymers. The 1\/8-inch shank diameter is a standard size compatible with collet-style chucks common on PCB drilling machines and precision spindle equipment. Series 105 designates the product family within SGS tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 75 wire size, 0.0210-inch decimal diameter for precision small-hole drilling\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point geometry reduces thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral with 30-degree helix angle promotes chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports bit strength at small diameters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in precision micro-drilling equipment and CNC circuit board drill machines accepting a 1\/8-inch shank diameter collet.

Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Secure the bit to the manufacturer-specified collet engagement depth to avoid runout. Inspect the cutting edges under magnification before use, as solid carbide bits at this diameter are brittle and susceptible to chipping if mishandled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.53 mm\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\u003eShank Diameter (Inch)\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3100 inches (7.87 mm)\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51741466263858,"sku":"07294","price":16.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4a828dcbd075bc1ddbf6666956f2aac.jpg?v=1788831652","url":"https:\/\/voomisupply.com\/products\/sgs-07294-circuit-board-drill-bit-no-75-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
