Drill Bit Set, Superior Hardness Drill Bits with High Precision Grinding HSS-CO Range 1.0-5.0 MM for Stainless Steel and Cast Iron (5 millimeters)

1. Made of M35 material, containing 5% cobalt, high hardness, and stable performance. 2. The 135-degree split point starts drilling immediately with less force and eliminates stubbing. 3. Ideal for drilling stainless steel, cast iron, sheet metal, steel plates, and angle iron. 4. With a high-quality finish and high grinding precision, the blade is sharp and precise. 5. It is widely used for drilling stainless steel sheets, automotive spring steel, and die steel.

Specifications: Descriptions: These drill bits are made of M35 material, containing 5% cobalt, high hardness, and stable performance. The cobalt steel extends the cutting edge life and maintains the cutting edge after resharpening. Ideal for drilling stainless steel, cast iron, sheet metal, steel plates, and angle iron.

Features: Made of M35 material, containing 5% cobalt, high hardness, and stable performance. The 135-degree split point starts drilling immediately with less force and eliminates "walking" on the workpiece. Ideal for drilling stainless steel, cast iron, sheet metal, steel plate, and angle iron. With a high-quality finish and high grinding precision, the blade is sharp and durable. It is widely used for drilling stainless steel sheets, automotive spring steel, and die steel. The cobalt steel extends the cutting edge life and maintains the cutting edge after resharpening.
