Serrated Jaws | Tongue and Groove Jaws |
Pointed jaws provide three points of contact on the workpiece. They are the most common choice for custom workholding.
Serrated Jaws—Serrated jaws work with most power lathe chucks from Kitagawa, LMC, Samchully, Toolmex, Bison, Seoam, and Auto Strong. Attach to your chuck with jaw nuts (not included).
Tongue and Groove Jaws— Tongue and groove jaws work with most manual lathe chucks from Bison, Toolmex, Buck, Samchully, Rohm, and Huron.
6061 Aluminum—6061 aluminum jaws are lighter in weight than steel jaws, so they can be turned at higher speeds with less wear on your machine.
1018 Low-Carbon Steel—1018 low-carbon steel jaws are more durable than aluminum. For repeated use, harden them after machining.

Square Jaws
 |  |
Serrated Jaws |
Square jaws have more contact with a workpiece than pointed jaws for a more secure grip. They’re lighter in weight than full-grip jaws, but their hold isn’t as tight.
Serrated Jaws—Serrated jaws work with most power lathe chucks from Kitagawa, LMC, Samchully, Toolmex, Bison, Seoam, and Auto Strong. Attach to your chuck with jaw nuts (not included).
6061 Aluminum—6061 aluminum jaws are lighter in weight than steel jaws, so they can be turned at higher speeds with less wear on your machine.
1018 Low-Carbon Steel—1018 low-carbon steel jaws are more durable than aluminum. For repeated use, harden them after machining.
