Featuring a geared 3-jaw Jacobs chuck — the same style found on the popular Foredom #30 handpiece — it accepts a wide range of bits and burs from 0 to 4.0 mm (5\/32\") in diameter, closing all the way down to zero for maximum versatility. This handpiece plugs directly into the Foredom HP4-917 Control Box (sold separately) and is operated via the control box dial or an optional variable speed foot control.\u003c\/p\u003e\u003cp\u003eCompared to the standard Foredom micromotor handpiece, the H.MH-120 delivers more torque while operating at a lower maximum speed of 20,000 RPM—making it well suited for heavier grinding and material removal tasks that benefit from added power over raw speed.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAdjustable geared 3-jaw Jacobs chuck accepts bits from 0 to 4.0 mm (5\/32\") in diameter\u003c\/li\u003e\n\u003cli\u003eChuck closes all the way down to zero—no minimum bit size required\u003c\/li\u003e\n\u003cli\u003eSpeed controlled via the HP4-917 Control Box dial or compatible variable speed foot control\u003c\/li\u003e\n\u003cli\u003eMaximum speed of 20,000 RPM with higher torque than the standard micromotor handpiece\u003c\/li\u003e\n\u003cli\u003ePlugs directly into the Foredom HP4-917 Control Box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eChuck Type\u003c\/th\u003e\n\u003ctd\u003eAdjustable Jacobs 3-jaw chuck\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChuck Capacity\u003c\/th\u003e\n\u003ctd\u003e0–4.0 mm (0–5\/32\")\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\u003eHandpiece Length\u003c\/th\u003e\n\u003ctd\u003e8-3\/32\" (206 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Diameter (cord end)\u003c\/th\u003e\n\u003ctd\u003e1-3\/8\" (35 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHandpiece Diameter (chuck end)\u003c\/th\u003e\n\u003ctd\u003e1-1\/64\" (26 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e1 lb 2 oz (510 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Control Box\u003c\/th\u003e\n\u003ctd\u003eForedom HP4-917 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eThis listing is for the \u003cstrong\u003emicrogrinder handpiece only\u003c\/strong\u003e.
