Burghiu Bosch 2 609 255 039, 2 buc.

Drill Bit Set Bosch 2609255039 contains two precision-ground twist drill bits made of high-speed steel, each 3.2 mm in diameter and 65 mm in length. These right-hand cutting drill bits are ground from solid metal for a consistent drilling rate and are suitable for drilling a wide range of materials including iron, alloyed and non-alloyed steels, non-ferrous metals, cast iron, cast steel and hard plastics. The set is designed for professional and DIY use; using coolant is recommended to extend tool life and improve chip evacuation.

Advantages

The Bosch 2609255039 bits provide accurate, repeatable holes thanks to precise grinding and solid HSS construction. Their universal geometry works across many materials, reducing the need to change tools between jobs. The compact set of two bits is convenient for carrying and storage, and the recommended use of coolant helps maintain cutting performance and durability.

How to use

Secure the workpiece and mark the drilling position. Install the 3.2 mm HSS bit in an appropriate drill chuck and ensure it is tightened correctly. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Apply steady, even feed pressure and periodically withdraw the bit to clear chips. Use coolant or cutting fluid when working with metals to reduce heat and improve hole quality.

Recommendations

For best results and longer tool life use appropriate cutting fluid, maintain correct spindle speed for the material, and replace bits when wear affects hole accuracy.
