The set spans nine punch sizes from 0.25 inches through 1 inch, giving technicians the range needed to fabricate or replace gaskets and seals on the job. A driving mandrel is included to protect punch faces during use. The full set ships in a custom-fit plastic case that keeps punches organized and protected between uses. At 2.1 pounds, the kit is compact enough to store in a service bag or toolbox.\u003c\/p\u003e\u003cp\u003eThis set is suited for trade professionals who need to fabricate custom gaskets, punch grommets, cut cork or felt insulation pads, or size rubber washers in the field. HVAC techs, plumbers, and pipefitters commonly keep a hollow punch set on hand for ductwork gaskets, access panel seals, and pipe insulation work. The standard punch style works with a hammer or mallet on a sacrificial backing surface. The included driving mandrel helps extend punch life and maintains center accuracy across repeated strikes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-piece set covering nine sizes: 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 3\/4, 7\/8, and 1 inch\u003c\/li\u003e\n\u003cli\u003eIncludes a driving mandrel for consistent, hammer-safe operation\u003c\/li\u003e\n\u003cli\u003eCustom-fit plastic case for organized storage and transport\u003c\/li\u003e\n\u003cli\u003eStandard punch style compatible with common mallet-driven technique\u003c\/li\u003e\n\u003cli\u003eSize range of 0.25 to 1 inch covers the most frequent gasket and grommet applications in trade service work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose use on soft materials including rubber, leather, cork, vinyl, and felt gasket stock typical in HVAC, plumbing, and mechanical maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHollow punches are hand tools driven with a hammer or mallet — no power source required. Place the material on a firm, sacrificial backing surface such as a hardwood block or end-grain cutting board to protect the punch tip and achieve a clean cut. Use the included driving mandrel to seat strikes evenly and avoid mushrooming the punch end. Inspect punch edges before use and keep them free of burrs to maintain cut quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Hollow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePunch Size Range\u003c\/strong\u003e: 0.25 to 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes Included\u003c\/strong\u003e: 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 3\/4, 7\/8, 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 9 punches, driving mandrel, custom plastic case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePunch Set Style\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Plastic Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.1 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: GENERAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S1274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GENERAL FILTERS","offers":[{"title":"Default Title","offer_id":51689655107890,"sku":"S1274","price":102.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5e36c66ce1468136d295960baae8108.jpg?v=1788262502","url":"https:\/\/voomisupply.com\/products\/general-s1274-hollow-punch-set-10-pc-0-25-to-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
