{"product_id":"foredom-k1020-microgrinder-jacobs-chuck-handpiece","title":"Foredom K.1020 Microgrinder With Adjustable Jacobs Chuck Handpiece","description":"\u003cp\u003eThe Foredom K.1020 Microgrinder Kit combines the power and torque of a flex shaft with the freedom of movement of a micromotor. At the heart of this kit is the first micromotor handpiece featuring an adjustable Jacobs chuck style design, similar to the popular Foredom #30 handpiece. The geared 3-jaw chuck accepts a wide variety of bits up to 4.0mm (5\/32\") in diameter and closes all the way down to zero—giving jewelers, metalsmiths, and bench workers exceptional versatility across tasks. The K.1020 is an excellent choice for deburring cast pieces, polishing, taking down weld seams, and moderate to heavy grinding.\u003c\/p\u003e\u003cp\u003eThis kit supports \u003cstrong\u003edual voltage operation—110\/120V or 220\/240V\u003c\/strong\u003e—selectable via a switch on the back of the control box, making it suitable for international use.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAdjustable Jacobs chuck style handpiece accepts bits up to 4.0mm (5\/32\") in diameter, closing down to zero\u003c\/li\u003e\n\u003cli\u003eHigh torque motor produces 9.24 oz\/in of torque—more than twice that of the standard Foredom H.MH-170 handpiece\u003c\/li\u003e\n\u003cli\u003eSpeeds up to 20,000 RPM, controlled by the dial on the control box or the included variable speed foot control\u003c\/li\u003e\n\u003cli\u003eDual voltage compatible: 110\/120V or 220\/240V with selector switch on control box\u003c\/li\u003e\n\u003cli\u003eControl box front features On\/Off Power, Forward\/Reverse Rotation, and Manual\/Foot Speed Control switches\u003c\/li\u003e\n\u003cli\u003eOverload Protection activates a red warning light and audible beeping alarm if the motor stalls\u003c\/li\u003e\n\u003cli\u003eAll Foredom micromotor handpieces are interchangeable with the Foredom micromotor control box—compatible with the 134.532 standard quick-change handpiece and 134.537 reciprocating handpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eK.1020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Speed\u003c\/th\u003e\n\u003ctd\u003e20,000 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChuck Capacity\u003c\/th\u003e\n\u003ctd\u003e0–4.0mm (5\/32\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChuck Type\u003c\/th\u003e\n\u003ctd\u003eGeared 3-Jaw #0 Jacobs Chuck with Key\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotor Torque\u003c\/th\u003e\n\u003ctd\u003e9.24 oz\/in (high torque motor H.MH-120)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Length\u003c\/th\u003e\n\u003ctd\u003e8-3\/32\" (206mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Weight\u003c\/th\u003e\n\u003ctd\u003e1 lb, 2 oz (510g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Diameter (cord end)\u003c\/th\u003e\n\u003ctd\u003e1-3\/8\" (35mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Diameter (chuck end)\u003c\/th\u003e\n\u003ctd\u003e1-1\/64\" (26mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInput Voltage\u003c\/th\u003e\n\u003ctd\u003e110\/120V or 220\/240V (dual voltage, selector switch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e134.533\u003c\/strong\u003e Control Box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e134.539\u003c\/strong\u003e High Torque Handpiece with Geared 3-Jaw #0 Chuck \u0026amp; Key\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e134.534\u003c\/strong\u003e Variable Speed Foot Control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e134.535\u003c\/strong\u003e Handpiece Cradle\u003c\/li\u003e\n\u003cli\u003eExtra Set of Motor Brushes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eThe H.MH-120 high torque handpiece delivers more than twice the torque of the standard Foredom H.MH-170 handpiece.
