The tilting table lowers completely below the disc, so you can use the full disc surface when the work calls for it. That range of access keeps large and awkward workpieces manageable.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eRack and Gear Table System Speeds Setup\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe precision table raiser uses a rack and pinion gear system controlled by a crank that moves the table smoothly and holds position without slipping. The table assembly is counterbalanced to make raising and lowering easier and to extend the service life of the lifting components. Adjustments are direct and repeatable.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eTilting Table Adds Versatility for Angled Work\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe table tilts 45 degrees downward and 15 degrees upward with a positive lock on the worm-and-sector gear system. A built-in protractor lets you set angles quickly, and a machinist's protractor can be used when high-precision angles are required. The miter gauge slot adds a second axis for grinding compound angles.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eRigid Column and Heavy-Duty Base Maintain Stability\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe rigid column and heavy-duty base keep the machine stable under load. A wrap-over guard covers the disc edge, and the low voltage protection switch prevents unintended restarts after a power interruption — an important safeguard in any production environment.\u003c\/p\u003e\n\u003cdiv class=\"one-fourth-column\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1188\/6562\/files\/JETJ-442120IndustrialDiscSander_480x480.jpg?v=1776573150\" alt='JET J-4421 20\" Industrial Disc Sander' style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"one-fourth-column\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1188\/6562\/files\/JETJ-442120IndustrialDiscSander_1_480x480.jpg?v=1776573150\" alt='JET J-4421 20\" Industrial Disc Sander' style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"one-fourth-column\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1188\/6562\/files\/JETJ-442120IndustrialDiscSander_5_480x480.jpg?v=1776573150\" alt='JET J-4421 20\" Industrial Disc Sander' style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"one-fourth-column-last\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1188\/6562\/files\/JETJ-442120IndustrialDiscSander_6_480x480.jpg?v=1776573150\" alt='JET J-4421 20\" Industrial Disc Sander' style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr style=\"clear: both;\"\u003e\u003c\/p\u003e\n\u003ch6 style=\"text-align: left;\"\u003eWhat's Included\u003c\/h6\u003e\n\u003ch3 style=\"text-align: center;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJET J-4421 20\" Industrial Disc Sander\u003c\/li\u003e\n\u003cli\u003eGrinding disc (in protective sleeve)\u003c\/li\u003e\n\u003cli\u003eTable raiser crank\u003c\/li\u003e\n\u003cli\u003eMiter gauge assembly\u003c\/li\u003e\n\u003cli\u003eDust chute\u003c\/li\u003e\n\u003cli\u003eHose adapter (1.5\" to 3\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eSpecs\u003c\/h6\u003e\n\u003ch3 style=\"text-align: center;\"\u003eJET J-4421 20\" Industrial Disc Sander Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel Number: J-4421-2 (220V 3Ph) \/ J-4421-4 (460V 3Ph)\u003c\/li\u003e\n\u003cli\u003eStock Number: JT9-577010 (220V) \/ JT9-577011 (460V)\u003c\/li\u003e\n\u003cli\u003eDisc Diameter: 20\"\u003c\/li\u003e\n\u003cli\u003eMotor: 3 HP, TEFC, 1725 RPM\u003c\/li\u003e\n\u003cli\u003eVoltage: 230V (J-4421-2) \/ 460V (J-4421-4)\u003c\/li\u003e\n\u003cli\u003ePhase: 3-Phase\u003c\/li\u003e\n\u003cli\u003eTable Size: 27-1\/2\" x 10-1\/2\"\u003c\/li\u003e\n\u003cli\u003eTable Slot: 3\/8\" x 3\/4\"\u003c\/li\u003e\n\u003cli\u003eTable Tilt: 45° downward \/ 15° upward\u003c\/li\u003e\n\u003cli\u003eOverall Dimensions (L x W x H): 30\" x 28\" x 53\"\u003c\/li\u003e\n\u003cli\u003eNet Weight: 397 lbs.\u003c\/li\u003e\n\u003cli\u003eShipping Weight: 529 lbs.\u003c\/li\u003e\n\u003cli\u003eWarranty: 2 Year\u003cbr\u003e\u003cbr\u003eWarning: Cancer and Reproductive Harm.

Vibration at the disc face causes uneven stock removal and surface defects that are difficult to correct. A balanced disc removes that variable so your results stay consistent from piece to piece.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eCast Iron Slotted Table Supports Accurate Work Positioning\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe large cast iron table gives you a solid, stable platform with a slotted surface for fixture and stop use. Cast iron holds flat without flex, which matters when you are pressing workpieces into the disc at consistent angles. The table tilt scale reads degree of tilt directly so you can set and confirm your angle without guessing.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eDie Cast Aluminum Miter Gauge Handles Plain and Compound Angles\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe standard miter gauge lets you register workpieces for both plain and compound miter work at the disc. Compound angles require accurate tool support on two planes at once, and the miter gauge holds that position through the cut. This keeps your angled surfaces clean and repeatable without needing secondary fixturing.\u003c\/p\u003e\n\u003ch4 style=\"text-align: left;\"\u003eHeavy Duty Steel Stand Keeps the Machine Stable at Floor Level\u003c\/h4\u003e\n\u003cp style=\"text-align: left;\"\u003eThe one-piece steel stand brings the J-4400A to a working height that keeps pressure comfortable and control consistent. A rigid base reduces movement during sustained contact passes.
