The MDDB52S 52-PC RPT™ 3\/8\" Drive Low-Profile Master Dual Action Driver (DAD) Set is the complete compact answer at this scale: 48 DAD bits across metric hex, SAE hex, star, and triple square profiles, the DFRB1090 17mm Hex Flex Head Low-Profile Ratchet built to drive them, and the adapters that connect the ratchet to standard 3\/8\" and 1\/2\" drive sockets. It is the first 3\/8\" master set to include the 17mm hex ratchet, and it extends the 3\/8\" DAD range well beyond the individual sets, from 4mm through 19mm, 1\/8\" through 3\/4\", T20 through T70, and a full M8 through M18 triple square run on a single drive size.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the set\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eDual Action Driver bits (48)\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetric Hex (16):\u003c\/strong\u003e 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAE Hex (13):\u003c\/strong\u003e 1\/8\", 5\/32\", 3\/16\", 7\/32\", 1\/4\", 5\/16\", 3\/8\", 7\/16\", 1\/2\", 9\/16\", 5\/8\", 11\/16\", 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStar, Torx compatible (11):\u003c\/strong\u003e T20, T25, T27, T30, T40, T45, T47, T50, T55, T60, T70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Square (8):\u003c\/strong\u003e M8, M9, M10, M12, M13, M14, M16, M18\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eDrive tools and adapters (4)\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDFRB1090: 17mm Hex Standard Flex Head Low-Profile Ratchet.\u003c\/strong\u003e Engages each DAD bit directly on its external 17mm hex through a pass-through retention cavity, for a combined height of just 27mm (1-1\/16\").\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDB17A: 17mm Hex Drive to 3\/8\" Square Drive Adapter.\u003c\/strong\u003e Lets the low-profile ratchet run standard 3\/8\" drive sockets and accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDDC17A: 17mm Hex Drive to 1\/2\" Square Drive Adapter.\u003c\/strong\u003e Extends the ratchet to 1\/2\" drive sockets and accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLPBSA: 3\/8\" Drive Spinner Adapter.\u003c\/strong\u003e Fast finger tightening and loosening before and after final torque.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEverything is packaged in a durable GripEdge case with a foam insert for clean organization, quick inventory checks, and fast resets.\u003c\/p\u003e\n\u003ch3\u003eThe engineering behind the grip\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPT™ tooth geometry that loads inward.\u003c\/strong\u003e Standard drivers concentrate stress on the fastener corners and push material outward until the recess rounds. The RPT™ profile relocates the contact point along the flank and directs force inward, forming a mechanical lock. Torque transfers into the fastener rather than around it, providing up to 50% more grip on new fasteners and up to 400% more grip on damaged ones across hex, star, and triple square profiles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Action Drive.\u003c\/strong\u003e Every bit runs on either a 3\/8\" square drive tool or its external 17mm hex.
