Description The Spyder Assorted Woodboring Power Bit Set bores up to 40x faster and with 50% less torque than conventional woodboring bits, making it ideal for fast, clean, precise applications using both low- and high-torque cordless drills. Featuring Stinger’s patent pending non-clogging, auto-feed tip technology, the Power Bit™ won’t wander, allowing for no-thrust drilling. The Spyder Assorted Woodboring Power Bit holes are extremely clean and burr-free, making them excellent for precise applications in hardwood, drilling through holes in laminated wood materials, and for stud drilling applications where wire will be pulled. The Spyder Power Bit™ makes clean holes like a Forstner bit while its auger-like flutes allow deep hole drilling. Not for use in wood with nails, screws, staples or other foreign objects.
