Built from high speed steel with a bright uncoated finish, this plug chamfer tap suits both blind hole and through-hole threading operations. It carries a Class 3B fit with an H3 thread limit, making it appropriate for close-tolerance work where thread accuracy matters. Overall length is 2.938 inches with a thread length of 0.75 inches (31.75 mm). The 3-flute geometry provides a balance of chip clearance and thread support across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for manual tapping operations on the benchtop or in a drill press setup where a tapping handle or wrench is used. The plug chamfer style — typically 3 to 5 threads of lead — makes it a general-purpose choice for starting a tap in either a blind or through hole. Common installation scenarios include job shop work, maintenance and repair operations, and production runs where a hand tap is the preferred method. The 3B fit class targets standard fastener thread tolerances used across most mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with plug chamfer for general-purpose starting in blind or through holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H3 thread limit for close-tolerance thread accuracy\u003c\/li\u003e\n  \u003cli\u003e3-flute straight flute design balances chip clearance with thread support\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping handles and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Secure the workpiece firmly and apply cutting fluid appropriate for the workpiece material before beginning the threading operation. Reverse the tap periodically to break chips, especially in blind hole applications. Inspect the tap for wear or chipping before each use — a damaged tap can produce out-of-tolerance threads or break off in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches (11.11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches (7.26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1002\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51707173896498,"sku":"C54598","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/504bbf1e8d39af81a6d19db38e00116d.jpg?v=1788438750","url":"https:\/\/voomisupply.com\/products\/cleveland-c54598-hand-tap-3-8-24-unf-plug-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
