The Stronghold Chuck is
operated by a key. Key operation provides two major advantages:
- One handed operation
- Solid holding power
The following features are standard on our chucks:
- quality materials
- nickel plated body
- hardened base jaws
- manganese phosphate coated scroll
This chuck (as do all our chucks) include our patented over extension
prevention system for added safety. This prevents the jaws from being over
extended and therefore preventing them from coming loose from the chuck
The key is supported in two places for longer life and accuracy. Gear teeth are
precision machined to guarantee that no teeth skip in use. When applying pressure, a 5 to
1 ratio assures powerful clamping.
The approximate weight of this chuck is 8 lbs.
