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
with over 400 patents.
With our professional spirit,
we focus on developing team relationships
with our customers that
help drive new product launches.
