These drill bits are the appropriate size for the Whiteside Adjustable Countersinks. Choose standard Jobber Drills for best economy. The optional Taper Point Drills are ideal for better control on entry and exit. The Taper Point resists the rapid pull-in tendency of gelcoat and other hard, thin materials. They also break through less abruptly, which helps reduce blowout on exit.
