Key number K2 fits the corresponding chuck series and uses a 0.25-inch pilot diameter to seat squarely into the chuck body for reliable engagement. At 0.17 pounds, it is a lightweight, single-piece tool suited for daily shop use. Machinists, maintenance technicians, and tool-room professionals reach for this key as a direct OEM-style replacement or a spare when the original is lost or worn.\u003c\/p\u003e\u003cp\u003eThis chuck key is appropriate for light industrial and professional trade shop environments where JACOBS-pattern chucks are standard equipment. It is commonly found at drill press stations in fabrication shops, maintenance facilities, and production floors. The K2 key number designation matches specific chuck body sizes, so verifying the chuck series before ordering is recommended. Compatibility with product numbers 2A and 2B makes it a practical replacement option across those chuck variants.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eK2 key number for direct fitment with matching JACOBS chuck series\u003c\/li\u003e\n\u003cli\u003e0.25-inch pilot diameter seats accurately into the chuck pilot hole\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.17 pounds for easy one-handed operation\u003c\/li\u003e\n\u003cli\u003eCompatible with product numbers 2A and 2B chuck variants\u003c\/li\u003e\n\u003cli\u003eSingle-piece construction with no moving parts to wear out\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with JACOBS chuck product numbers 2A and 2B.

Power down and lock out the drill press or lathe at the disconnect before inserting or removing the chuck key. Do not use an extension on the chuck key handle, as over-tightening can damage chuck jaws and the spindle arbor. Replace any chuck key that shows signs of rounding at the gear teeth or pilot wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Number\u003c\/strong\u003e: K2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Product Numbers\u003c\/strong\u003e: 2A, 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: #2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JACOBS CHUCK","offers":[{"title":"Default Title","offer_id":67908579131698,"sku":"#2","price":21.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e26330719c778bb4899e6a62f2cb7379.jpg?v=1791184009","url":"https:\/\/voomisupply.com\/products\/jacobs-2-drill-chuck-key-k2-0-25-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
