We are 115+ years old and
have been focusing on chucks since 1902.
We were granted
the first US chuck patent in 1902
 and started the modern keyless chuck 
industry for portable tools.
We are the world leader 
for chuck manufacturing and 
product innovation 
with over 400 patents.
With our professional spirit, 
we focus on developing team relationships 
with our customers that 
help drive new product launches.
With our Lean Manufacturing system 
and experience, 
we provide high quality, 
on-time delivery, and shorter lead times.
