Built from high-speed steel with a bright uncoated finish, it delivers reliable thread formation across a range of common metals. The 4-flute straight-flute geometry provides chip clearance and stable cutting action in hand-tapping operations. At 2.125 inches overall length with a 0.38-inch threaded section, this tap fits standard tap wrench configurations. The bottoming chamfer allows threading to the bottom of a blind hole, making it the correct choice when thread engagement must extend to the full depth of the bore.\u003c\/p\u003e\u003cp\u003eThis tap is suited for job shop, maintenance, and production applications where 8-32 threads are required. The bottoming chamfer style is commonly used as the final tap in a sequence following a taper or plug tap to achieve full thread depth in blind bores. It is appropriate for hand-tapping operations on alloy steel, carbon steel, aluminum, and free-machining stainless steel. Series 1003 from CLEVELAND covers standard inch-series hand taps, and this H2 thread limit ensures finished threads fall within the 3B class of fit tolerance range for standard fastener compatibility.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design for chip clearance and cutting stability\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across multiple materials\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ground to 3B class of fit for standard tolerance threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 8-32 UNC specification\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hand tap for use in standard tap wrench holders accepting a 0.168-inch shank diameter with a 0.25-inch square drive end.

Secure the workpiece before tapping and apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically to break chips, particularly in blind-hole applications. Follow applicable shop safety practices when working with cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.38 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches (4.27 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.131 inches (3.33 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\u003eSeries\u003c\/strong\u003e: 1003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: C54271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712202768690,"sku":"C54271","price":21.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7532ef53f1449d007117fb19c48e6a4e.jpg?v=1788485069","url":"https:\/\/voomisupply.com\/products\/cleveland-c54271-hand-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
