Premium Countersink Bits
Even the humble countersink bit can be improved, right?
A new set of these bits from Woodworker’s Supply takes up
where generic sets leave off. The new bits make absolutely
smooth holes, defy clogging and come with a set of stop
collars unlike any you’ve seen before.
The set contains four bits matched for #6, #8, #10 and
#12 screws. The countersink bodies are 3/8" dia. for the
#6, #8 and #10 bits, and 1/2" dia. for the #12 bit. They are
hardened to Rc64 for a long life and are 1-1/4" long, allowing
you to drill a deep, accurate counterbore. As with all
countersink bits, you can vary the drill bit’s length by loosening
a set screw. However, these bits have two set screws,
an arrangement that further prevents the bit from slipping.
Two stop collars are included: one for the #6, #8 and
#10 bits, and one for the #12 bit. A white nylon ring spins
freely on the end of each stop collar to prevent the collar
from marring the wood. The stop collars also have “windows"
above the ring to allow chips to eject, a convenient
feature most stop collars don’t have. The set is packaged in
a handsome burl-fi nish box, worthy of the fi ne tools inside.
