- Size - Drilling diameter: 4.7mm (0.185"); round shank diameter: 4.7 (0.185"); drilling depth: 46mm (1.81"); total length: 80mm (3.15").
- Material - Drill bit set for metal is constructed of M35 high speed steel material, featuring high hardness, high strength, heat resistance, wear resistance, and ensuring long-lasting performance. The smooth surface also reduces friction, ensuring faster drilling processes.
- Features - The straightforward shank ensures easy chucking into standard drill machines, providing a secure fit for accurate drilling operations without slippage. Precision cutting edging penetrates quickly with less pressure, providing optimal chip removal.
- Applications - M35 cobalt drill bit set with straight shank is specifically designed for high-performance drilling tasks, suitable for a wide range of materials, including hard metal, steel, cast iron, wood and plastic. NOT for tiles, concrete, walls, stones.
- Note - Ensure the jobber drill bit is appropriate for the material you're drilling into. Apply lubricant, such as cutting oil or coolant, especially when drilling metal which reduces friction, heat, and prolongs the bit's life.

Specification
- M35 twist drill bits with straight shank are specifically designed for high-performance drilling tasks. The M35 material features high hardness, high strength, heat resistance, wear resistance, and ensuring long-lasting performance.
- The cobalt addition improves the bit's ability to withstand high drilling temperatures, preventing premature dull and ensuring efficient performance during prolonged use.
- These high speed steel drill bits are good for drilling through harder metals, stainless steel, cast iron, and other tough materials, ensuring precise, clean holes, thereby enhancing productivity in various industrial applications.
- Use the correct drill speed setting. Generally, harder materials require slower speeds to prevent overheating and bit damaging.
- Apply lubricant, such as cutting oil or coolant, especially when drilling metal. This reduces friction, heat, and prolongs the bit's life.
