Quick-Chuck 80040K - Brake Lathe 3-Jaw Double Taper Chuck Kit
Part No. 80040K (Ammco Part# 940921)
The Double Chuck Kit is designed for machining hub-less drums and rotors, including composite applications, on passenger vehicles and trucks up to 1-ton. The chuck features an auto side and a truck side, allowing the operator to flip the chuck over instead of changing jaws.
With fewer pieces to store, maintain, and replace, this kit helps reduce setup time while providing a self-centering grip on the center hole. The added weight and mass of the double chuck with backing plate helps reduce chatter and vibration during hub-less drum and rotor machining.

Features:
- Double-sided chuck design with an auto side and a truck side
- Passenger car jaws are permanently mounted on one side
- Truck jaws are permanently mounted on the opposite side
- No jaws to change when switching between passenger vehicle and truck applications
- Includes 2 sets of concentric, expanding jaws to grip the center hole and eliminate the need for cones
- Fits popular 1 in. arbor brake lathes
- Handles virtually all hub-less drums and rotors, including composite applications, through 1-ton vehicles
- Self-centering design helps eliminate runout and setup problems
- Double chuck and backing plate mass helps reduce chatter and vibration
- Fewer pieces to store and maintain compared to multi-piece adapter setups

Shipping Responsibility Disclaimer
Once a package is marked as "Delivered" by the carrier, we are no longer responsible for its whereabouts unless you specifically requested a signature requirement at checkout. If no signature is requested and the package goes missing after delivery, we cannot be held liable for the loss. Additionally, any delivery issues must be reported to us within 12 hours of the marked delivery time. Failure to notify us within this timeframe may result in a forfeiture of claims, as delayed reporting significantly reduces the chances of locating a misdelivered package.

SHIPPING COST DISCLAIMER
Shipping can be very complicated, especially with LTL Freight items, and it can be challenging to always quote the exact shipping price with complete accuracy. We do not make money from shipping and only pass along the actual shipping cost charged by the carrier.
If the shipping cost we quoted or provided is less than the actual amount charged by the carrier, we reserve the right to not honor the sale at that shipping price and may cancel the order if necessary. However, before any order is canceled, you will be given the opportunity to pay any additional shipping charges if you choose to do so.
