POWER CHUCKS

Pie Jaw® Pie-Shaped Soft Jaws		Inch Serrations FEATURES: Full-grip jaws for increased surface contact on large diameter or thinwall parts, to prevent distortion and marring. Also ideal for fixturing non-cylindrical parts. Cast aluminum material. 1/16" x 90° serrations (3/32" x 90º serrations on jaws for 16" and larger chucks). SIZES: Available for chuck sizes from 5" to 18" diameter, in standard height and extra high, and also in oversize diameters — see Dimensions page for part numbers. Note: in most cases, two-jaw power chucks use the next-larger-diameter top jaws. DESIGN CONSIDERATIONS & SAFETY PRECAUTIONS: The "critical dimensions" shown in the dimension tables must match your master jaw, although outside dimensions can be different. Please check before ordering. When using extra-high or oversize-diameter top jaws, maximum allowable spindle RPM will be reduced somewhat. Please consult your chuck's operating manual. MATERIAL (ALUMINUM): 319 aluminum alloy.
