Extra-Long Drill Bits

Our long drill bits are must-have tools for your long-reach drilling projects and hard-to-reach places. When you try our aircraft drill bits, you’ll have the ability to achieve deep drilling through thicker materials like cast iron, stainless steel, bronze, and titanium. Our premium M2 and M42 Long Boy extra-long drill bits vary in width sizes from 1/16″ to 1-1/4″. We even manufacture drill bits up to 12 feet long that are great for long-reach drilling, beam drilling, and thick material drilling for extra-deep holes. You’ll get the best results when you use our long drill bits for metal that hold up against very strong structures and maintain a long-lasting performance.

Extra-long drill bits improve efficiency in construction, woodworking, and metalworking projects that require deep drilling. The right drill bit length improves precision and efficiency when drilling through thick or layered materials.

Our selection includes HSS and premium cobalt steel extra-long drill bits. Whatever your budget and project requirements, we have the high-performing long drill bits you need to efficiently cut deep or extra-deep holes.
