Premium M35 Cobalt Construction: </strong>Made with high-quality M35 steel and 5% cobalt, these drill bits offer superior hardness and exceptional heat resistance. With a Rockwell hardness up to 67, they outperform standard HSS bits by up to 12 times for long-lasting performance.<br /> <strong>2. Self-Centering 135° Split Point:</strong> The round shank twist drill bits set's 135° split point design ensures fast, precise drilling with minimal pressure. Self-centering action prevents walking, allowing for quick penetration and accurate hole placement: perfect for both professional and DIY projects.<br /> <strong>3. Efficient Chip Removal and Fast Drilling:</strong> The twist drill bit set's fully ground, straight shank design provides secure clamping and accurate centering. Enhanced flute geometry quickly clears chips and debris for smoother, faster drilling, reducing effort and improving overall efficiency.<br /> <strong>4. Versatile Metal Drilling Applications:</strong> Specially engineered for metals with hardness below HRC38, these cobalt drill bit sets excel on stainless steel, copper, cast iron, galvanized pipes, iron, and aluminum alloys. Not suitable for hardened or high-carbon steel; adjust speed if penetration is difficult.<br /> <strong>5. Precision Engineering and Re-Sharpenable Tips: </strong>Each cobalt jobber twist drill bit set features a heavy-duty, fully ground body that minimizes burrs and ensures exact hole diameters. The solid cobalt steel construction allows for re-sharpening, providing the lowest cost per hole and extending the tool's usable life.<br /> <br /> </span> </p><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China</span><br /> <span>Material: High Speed Steel</span><br /> Packing size: 155.00x110.00x40.00mm6.1x4.33x1.57inch<br /> 51 pieces (1-6mm): 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0 mm<br /> <br /> <p> <strong>Note:</strong><br /> Due to different monitor settings and lighting conditions, the actual color of the item may vary slightly from the pictures.
