RUKO STS 8006 5-Piece Chuck Jaw Set for 100 mm 4-Jaw Lathe Chuck

This RUKO STS 8006 jaw set is a direct replacement for 100 mm 4-jaw lathe chucks, supplied as a complete set of five hardened, reversible jaws. Unlike generic jaws that sacrifice grip for price, the STS 8006 uses high-quality tool steel with precision ground surfaces and a stepped profile to hold cylindrical, square, or irregular workpieces securely during turning and boring.

Highlights

• Set of 5 hardened, reversible jaws for 4-jaw lathe chucks
• Compatible with 100 mm chuck diameter
• Precision ground from high-quality tool steel for accurate clamping
• Heat-treated for extended wear resistance
• Stepped jaw profile grips a wide range of workpiece shapes

In daily use

The jaws mount with standard bolts, making replacement straightforward. Their reversible design doubles the usable gripping surfaces, and the hardened material holds up to repeated clamping cycles in metalworking shops.
