The Woodchuck Drilling System is very similar to the old Planetor Bits in our last catalog but with a number of improvements. Machined from a solid piece of steel and hardened for long tool life, one shaft fits all drill heads. Drill more holes per hour and sharpen easily with a flat file. All bits have 3/8-24 threads.
