{"product_id":"archimedian-push-drill-spring-1-2mm","title":"Archimedian Push Drill With Spring","description":"\u003cp\u003eThe Archimedian Push Drill with Spring is an indispensable bench tool for jewelers and metalsmiths who need precise, controlled drilling with small twist drills. Designed around the ancient Archimedian screw principle, this hand-powered drill lets you start and drill holes with far greater accuracy than motor-driven tools — making it ideal for delicate work where a wandering bit or broken drill would be costly.\u003c\/p\u003e\u003cp\u003eTo use, place one thumb and finger on the swivel top while the other hand slides the knurled rotating rod up and down the twisted shaft. This push-and-release motion spins the bit at a speed entirely under your control, dramatically reducing the risk of drill breakage or drift from your center punch mark. The return spring automatically resets the rod for the next stroke, keeping your workflow smooth and efficient.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eArchimedian screw-action design for smooth, controlled hand-powered drilling\u003c\/li\u003e\n\u003cli\u003eReturn spring automatically resets the rotating rod between strokes\u003c\/li\u003e\n\u003cli\u003eSwivel top allows one-handed stabilization while the other hand drives the drill\u003c\/li\u003e\n\u003cli\u003eKnurled rotating rod provides a secure, non-slip grip during use\u003c\/li\u003e\n\u003cli\u003eUser-controlled speed reduces drill breakage and prevents bit wander\u003c\/li\u003e\n\u003cli\u003eIdeal for starting holes and drilling with small twist drills\u003c\/li\u003e\n\u003cli\u003eCollet accepts twist drills up to 1.2mm (no larger than size #56)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Collet Capacity\u003c\/th\u003e\n\u003ctd\u003e1.2mm (size #56 \/ 0.0465\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Length\u003c\/th\u003e\n\u003ctd\u003e4-1\/4\" (110mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpring Included\u003c\/th\u003e\n\u003ctd\u003eYes — return spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Drill Sizes\u003c\/th\u003e\n\u003ctd\u003eTwist drills under 1.2mm diameter (up to size #56)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eIndia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 × Archimedian Push Drill with Return Spring\u003c\/li\u003e\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43583863849174,"sku":"128.230S","price":3.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/archimedian-push-drill-with-spring-otto-frei.jpg?v=1719956476","url":"https:\/\/www.ottofrei.com\/products\/archimedian-push-drill-spring-1-2mm","provider":"Otto Frei","version":"1.0","type":"link"}
