It carries a 4-40 UNC thread form with 2 right-hand flutes and a 45-degree helix angle that efficiently evacuates chips up and out of the hole during the cut. The modified bottoming chamfer allows threading close to the bottom of a blind hole while maintaining thread quality. Manufactured from M42 powdered metal, the tap offers enhanced wear resistance compared to standard HSS tooling. The bright, uncoated finish is suitable for general-purpose tapping across most recommended material groups. This tap is installed by machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThe 40024-010 is rated for blind hole threading applications in aluminum, brass, bronze, carbon steel, copper, magnesium, stainless steel, wrought aluminum alloy, and zinc. Its fast flute style and 45-degree helix are particularly effective in softer and gummy materials where chip packing is a concern. The BX200 series is sized for small-diameter, fine-pitch work where tool control and consistent thread form are critical. Overall length is 1-7\/8 inches, with a thread length of 0.56 inches, making it suitable for compact workpiece geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form, right-hand thread direction, H4 thread limit for consistent oversize tolerance control\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle with fast flute style for efficient chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eM42 powdered metal construction for improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eRated for 9 material types including stainless steel, carbon steel, aluminum, brass, and copper\u003c\/li\u003e\n  \u003cli\u003eOversize designation confirms tap is ground to produce threads within H4 tolerance class\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in aluminum, brass, bronze, carbon steel, copper, magnesium, stainless steel, wrought aluminum alloy, and zinc.

Power down and lock out the machine before changing tooling. Use an appropriate cutting fluid or tapping compound for the workpiece material, particularly when tapping stainless steel or copper alloys. Do not reverse the tap before it has completed the threading pass in blind hole applications, as chip buildup can cause tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BX200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40024-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972339073330,"sku":"40024-010","price":61.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fcca253baaa1c2598cbff31e44f7389.jpg?v=1789966440","url":"https:\/\/voomisupply.com\/products\/balax-40024-010-spiral-flute-tap-4-40-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
