Dormer Drill Bit, Steam-Tempered Finish, 118° Drill Point - A110 Series - A110 3.3MM


If you're boring holes in hard-to-reach areas, you can count on this drill bit from Dormer. Its extra-long length of 106mm is handy for making deep holes or reaching spots that are tricky to access. The conventional 118° point ensures strength and is easy to regrind when needed, so you can keep using this bit for years to come. For convenient use, it can bore to a depth of up to six times its 3.3mm diameter before its right-turning mechanism has any trouble evacuating waste material.
