The key features a 7\/32 inch pilot diameter, which determines the pin that engages the chuck body during operation. Machined to fit the chuck precisely, it delivers the torque needed to secure or free drill bits without slipping or rounding out the chuck ports. This type of accessory is standard equipment for maintenance techs, machinists, and shop personnel who work with keyed drill chucks on a regular basis.\u003c\/p\u003e\n\u003cp\u003eThe T4 chuck key is used wherever a K7-style keyed chuck appears in a workshop or production setting. Typical applications include drill press maintenance, portable drill servicing, and toolroom operations. It suits both light-duty and moderate-duty drilling setups where a keyed chuck is preferred over a keyless design for positive bit retention. The compact size and low weight make it easy to store at the machine or on a tool board.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK7 key number for direct engagement with compatible K7-series chuck bodies\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch pilot diameter for precise fit in the chuck pilot hole\u003c\/li\u003e\n  \u003cli\u003eCompatible with product numbers 7 and 7B per manufacturer specifications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy handling and storage\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction for straightforward use without additional components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with JACOBS product numbers 7 and 7B as stated in manufacturer specifications.

Before changing or securing a bit, ensure the drill press or power tool is powered off and unplugged or locked out per applicable OSHA lockout\/tagout procedures. Insert the pilot pin fully into the chuck pilot hole before applying torque to avoid damaging the chuck teeth. Store the key away from the chuck when the machine is in operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: K7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Product Numbers\u003c\/strong\u003e: 7, 7B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: JACOBS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67906872738098,"sku":"T4","price":19.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05d3f496424125823715c75b64aedacc.jpg?v=1791172220","url":"https:\/\/voomisupply.com\/products\/jacobs-t4-drill-chuck-key-k7-7-32-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
