3-35/64-Inch Overall Length, Right-Hand Rotation. 2 spurs, 2 precision ground cutting edges, long-lasting cutting performance. Drill precise flat bottom holes with no chipping in any thickness of soft wood. For drilling holes in any direction and making arched openings. For drilling partially overlapped flat bottom holes or niches used to fix supports.
Exactly as described but the quality may not be the best. After several uses, transparent shavings are visible on the metal and are slightly discolored, as if burned. Used only with wood.
The drill I received was for drilling oversized holes. Upon inspection of the bit, the edges of the bit were swollen, creating an oversize issue. I took a diamond stone to knock off the ridges and now it's perfect!
In my workshop, I like to make devices and accessories that often contain moving parts. This drill bit is ideal for drilling holes for a regular skate bearing. I'm using it now to make a wooden kinetic sculpture with these bearings. It works great!
