If you’re matching hinge hardware or need clean, flat-bottom holes for furniture work, the Mollom 11/16″ (17.5mm) Forstner drill bit is built for accuracy and repeatable results. It uses a YG8 carbide positioning drill and cutting blades, paired with a No. 45 steel shank designed to resist bending during use.

This bit is sized for 17.5mm (11/16″) cuts, with an 8mm (5/16″) round shank, 60mm (2-3/8″) drilling depth, and 94mm (3-11/16″) overall length. The 1.70mm thick YG8 blade is designed for extended service life compared with thinner blades, making it a practical choice for frequent drilling tasks.
For best results, keep the drill perfectly vertical and secure your workpiece (a vise is recommended). Start at a slow speed until the bit is fully located, then increase speed gradually. The manufacturer suggests controlling speed at 2200–2500 RPM.
