Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during tapping operations. The four-flute straight flute geometry provides good chip control in a wide range of workpiece materials. At 4.25 inches overall length with a 2-inch thread length, this tap fits standard tap wrench drives via its 11\/16-inch square drive end. It is sized to cut Class 3B threads to an H3 thread limit, making it suitable for close-tolerance fastener applications in production and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in metalworking applications across general manufacturing, maintenance, repair, and toolroom settings. It is suited for threading alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces. Right-hand thread direction makes it compatible with standard tap wrench and tapping head setups. The plug chamfer style — with a moderate lead of approximately 3 to 5 threads — makes it useful for both starting threads in through-holes and threading blind holes where adequate clearance exists at the bottom of the hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-16 UNF right-hand thread form cut to Class 3B fit and H3 thread limit\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life compared to uncoated HSS taps\u003c\/li\u003e\n\u003cli\u003eFour-flute straight flute design for use in blind hole and through-hole threading\u003c\/li\u003e\n\u003cli\u003e4.25-inch overall length with 2-inch thread length and 0.59-inch shank diameter\u003c\/li\u003e\n\u003cli\u003eCompatible with alloy steel, carbon steel, aluminum, and free-machining stainless steel\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — suitable for hand tapping and standard machine tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap wrenches and tapping heads accepting a 0.44-inch square drive.

Always ensure the workpiece is securely fixtured and the tap is started square to the hole to prevent tap breakage. Use an appropriate cutting fluid for the workpiece material being threaded. For blind hole applications, verify sufficient thread depth clearance before tapping to avoid bottoming the tap under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1002TN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C55146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722836771122,"sku":"C55146","price":124.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edf405b7fcaecd6bf6c5ddab20cf2e3c.jpg?v=1788596644","url":"https:\/\/voomisupply.com\/products\/cleveland-c55146-hand-tap-3-4-16-unf-plug-rh-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
