The bit measures 0.0550 inches (wire size 54) in cutting diameter with a 1\/8-inch shank diameter and an overall length of 1.5 inches. The 130-degree four-facet point geometry reduces walking and delivers clean entry holes in thin, layered materials. Uncoated solid carbide construction provides the rigidity and edge retention required when drilling through abrasive or composite substrates at high spindle speeds. Licensed machinists, PCB fabricators, and precision machine operators are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC drilling machines, drill presses, and precision hand-held equipment where tight positional tolerances are required. The regular spiral with a 30-degree helix angle promotes consistent chip evacuation during through-hole drilling. It is applicable across a wide range of workpiece materials including aluminum, stainless steel, titanium, cobalt alloy, copper alloy, cast iron, nickel, plastics, and fiber-reinforced polymers. The two-flute configuration and tapered web design support clean hole geometry in both metallic and non-metallic substrates common in electronics manufacturing and precision fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 54 cutting diameter of 0.0550 inches (1.40 mm) for precise small-hole drilling\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point reduces drill walking and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides high rigidity and edge retention in abrasive materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral with 30-degree helix angle supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces thrust force during drilling\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to -0.0003 to +0.0000 inches for tight positional control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC PCB drilling machines and precision drill presses accepting a 1\/8-inch straight shank.

Ensure the machine spindle and collet or chuck are fully de-energized and at rest before changing bits. Verify the 1\/8-inch shank seats fully and is secured without runout before beginning a drilling cycle. Follow machine manufacturer guidelines for spindle speed and feed rate when working with small-diameter carbide tooling, as carbide is brittle and susceptible to breakage under side load or excessive feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 1.40 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\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.4000 inches (10.16 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\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\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: 07335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740137029938,"sku":"07335","price":16.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71f601639383915ed15c9872bcccbc80.jpg?v=1788822768","url":"https:\/\/voomisupply.com\/products\/sgs-07335-circuit-board-drill-bit-size-54-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
