If you routinely drill into metal, steel, or aluminum and want a dedicated 1/4 inch size on hand, this Yellow Paw 3-pack is built for tougher jobs. The bits use M35 cobalt steel (5% cobalt per the manufacturer) paired with a Titanium Aluminum Nitride (TiAlN) finish for added hardness and oxidation resistance.

A 135° split point helps the bit start more accurately—especially on stiffer materials where “walking” can be an issue. Each bit measures 4 inches overall with a 2-3/4 inch flute/working length, and the set comes with a plastic storage case to keep spares organized.
- 1/4″ (6.35 mm) cutting diameter; 4″ total length with 2-3/4″ flute/working length
- M35 cobalt steel (5% cobalt) with Titanium Aluminum Nitride (TiAlN) finish
- 135° split point to help reduce walking during starts
- 2-flute spiral design with round shank
- 3-pack includes a plastic storage case
Good fit for DIYers and pros who prefer keeping multiple identical bits ready—use one, keep one as a backup, and store one for the next project.
