Abbott Workholding Products KTTB212P Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTTB212P is a soft lathe chuck jaw designed for precision turning operations on metal lathes. Manufactured from 6061 aluminum, this serrated-interface jaw allows machinists to machine the gripping surface to a custom bore, providing accurate, repeatable part location. The jaw measures 12 inches in overall width and 2 inches in overall height. A serrated base interface with a slot width of 0.8270 inches mates directly to compatible chuck bodies. The 0.6299-inch fastener size and 1.1811-inch center-to-center mount hole spacing are key dimensions for fit verification before ordering. This is a 3-jaw set configuration suited for round workpiece clamping.

Soft lathe chuck jaws are used in both manual and CNC turning applications where hard jaws would damage the workpiece finish or where tight concentricity is required after boring the jaw face to size. This jaw set is appropriate for production and job-shop environments handling parts that require custom gripping profiles. The 6061 aluminum construction keeps rotational mass low while still providing adequate rigidity for light to moderate turning cuts. Licensed machinists and CNC lathe operators are the primary installers and users of this component.

Key Features

• Serrated jaw interface for secure, indexed engagement with compatible chuck bodies
• 6061 aluminum construction reduces chuck weight and allows easy re-boring to custom diameters
• 12-inch overall width and 2-inch overall height support larger workpiece diameters
• 1.1811-inch distance between mount hole centers for precise dimensional fit verification
• 0.8270-inch slot width and 0.8268-inch groove width for consistent serration engagement
• 3-jaw configuration for standard round workpiece clamping

Compatibility

Designed for use with 12-inch diameter lathe chucks that accept a serrated jaw interface. Verify mount hole center distance of 1.1811 inches and fastener size of 0.6299 inches against the chuck body specification before installation.

Installation Notes

Installation and jaw boring should be performed by a qualified machinist familiar with lathe chuck service procedures. Before removing or installing chuck jaws, the lathe spindle must be fully stopped, the machine powered down, and the chuck locked or secured against rotation. Bore the soft jaw face in-place on the chuck at the intended clamping diameter to ensure maximum concentricity. Follow the chuck manufacturer torque guidelines for jaw retention fasteners.
