1/4" x 12" Auger Drill Bit with a 3/16" Shank. Solid center design for rigidity when boring. Coarse screw point provides fast boring in hard and soft woods. Quality Guaranteed.
Used for drilling holes in 6x6 inch wooden beams. I drilled 4 holes and in the next one the drill bit hit the knot and twisted as shown in the picture.
Need an auger to 'help' the pellets in my pellet gravity stove. Bought two and they worked great. Unfortunately I can't tell you how they might work as drills, but hey, multitasking is good!
When trying to drill through a pine wood, the drill bit dug in half an inch before it started spinning. A spiral cut that unwinds and doesn't bite into soft wood. It looks like untempered metal considering how flexible it is. Rather spend a few euros more and buy a better drill.
