GMTOOLS 99 Pcs Drill Bit Set — Titanium Coated HSS, 135° Tip, 1/16-3/8 inch | Self-Centering

All-in-one drill bit kit for versatile projects

GMTOOLS 99 Pcs Drill Bit Set combines high-speed steel with a titanium coating to deliver sharper edges and longer durability. These bits are designed to clear chips quickly, helping you drill more efficiently through iron, aluminum, copper, wood, and plastic. The 135° tip improves centering and reduces wandering on initial contact, making setup smoother for repairs, installations, and hobby projects.

Self-centering geometry keeps the bit aligned as you start, often eliminating the need to pre-drill pilot holes in a range of softer and some harder materials. This feature supports clean starts and consistent hole diameters across tasks such as cabinetry, metalwork, and craft projects.
