AWTOOLS AW SPIRAL STEP DRILL BIT SET M2-TiAlN 3 ks

The AWTOOLS AW SPIRAL STEP DRILL BIT SET M2-TiAlN 3 pcs is a professional-grade set of spiral step drill bits designed for efficient drilling, reaming, and deburring in a single pass. Made from high-speed steel M2 with a titanium aluminum nitride (TiAlN) coating, these bits offer exceptional heat and wear resistance, ensuring long-lasting performance. The hexagonal 1/4 inch shank provides a secure grip and prevents slipping. Each bit features a self-starting tip for precise hole placement without walking. Ideal for use on sheet metal, plastic, wood, non-ferrous metals, and thin steel up to 5 mm thickness. Supplied in a durable plastic storage case for organization and protection.

Advantages
