Imported 3-Jaw Lathe Chuck Jaw Set UAE
Features
This Imported 3-Jaw Lathe Chuck Jaw Set is a direct replacement set of hardened steel jaws designed for 3-jaw self-centering lathe chucks used on manual and CNC lathes. Available across chuck sizes from 4 inch to 18 inch, and in the three most common serration and step patterns used across the industry, 60 degree, 90 degree and 120 degree, this set lets workshops match the exact tooth spacing required by their existing 3-jaw scroll chucks. Each jaw is machined and hardened for long service life under repeated clamping cycles, resisting wear from the scroll gear engagement that drives simultaneous, self-centering movement of all three jaws together. The jaws are supplied as a matched three-piece set, numbered for correct sequential fitting into the chuck body so that concentricity and centering accuracy are maintained after installation. Because the set is stocked across the full size range, workshops running multiple 3-jaw chucks can standardize on a single supplier for jaw replacements rather than sourcing odd sizes individually from several places. This reduces downtime when a jaw is damaged, worn out of tolerance, or lost during a job change. Correctly matched jaw sets keep chucks holding round, hex and irregular stock securely and concentrically during operation. These jaw sets are suitable for turning, facing, boring, drilling and general workholding tasks across mild steel, stainless steel, aluminium, brass and other common workshop materials. All sizes are stocked in Dubai for fast turnaround and same-day dispatch to workshops and machine shops across the UAE.
How to Use
Identify the exact chuck size in inches and the serration or step pattern, 60 degree, 90 degree or 120 degree, stamped on your existing jaws or specified in your chuck manual before ordering a replacement set. Fitting the wrong degree pattern will prevent the new jaws from meshing correctly with the scroll or pinion mechanism inside the chuck body. Open the chuck fully using the chuck key, then remove the worn or damaged jaws one at a time, keeping track of their numbered position, commonly marked 1, 2 and 3, since 3-jaw scroll chucks require jaws to be installed in the correct sequence to maintain self-centering accuracy. Clean the jaw slots and scroll threads of swarf, coolant residue and old grease before fitting the new jaw set. Insert each new jaw into its corresponding numbered slot and engage it with the scroll thread, then close the chuck gradually while confirming each jaw tracks smoothly and evenly toward center. Once fitted, check runout with a dial indicator on a test bar and re-seat any jaw that shows excessive runout. Lightly oil the scroll mechanism periodically after installation to keep jaw movement smooth and to extend the working life of both the jaws and the chuck body. Always disconnect or lock out the lathe spindle drive before servicing chuck jaws, keep hands clear of the closing jaws, and never operate the chuck with jaws only partially engaged in their slots.
Specifications
This listing covers the full range of 3-jaw lathe chuck jaw sets carried by SAN Tools, with each variant identified by chuck size in inches and by serration or step pattern in degrees. Use the size and degree options on this page to select the exact combination required for your chuck body, and check your existing jaw stamping or chuck documentation if you are unsure which degree pattern your chuck uses. Product type is a replacement jaw set for 3-jaw self-centering lathe chucks, supplied as a matched, numbered three-piece set per size and degree combination. Chuck sizes available in this range span 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, 12 inch, 15 inch and 18 inch. Serration and step pattern options are 60 degree, 90 degree and 120 degree, which are the common industry designations for chuck jaw tooth spacing and do not indicate a specific proprietary geometry. Jaws are supplied in hardened steel construction for wear resistance under repeated clamping cycles. Compatibility is with 3-jaw self-centering scroll chucks of the matching size and degree pattern, including common workshop brands, though buyers should always confirm fit against their existing jaws before installation. Typical applications include manual and CNC lathe turning, facing, boring, drilling and general workholding. Vendor for this range is Imported, and all sizes and degree options are held in stock at the SAN Tools warehouse in Dubai, UAE, for same-day dispatch on confirmed orders.
