Drill Bits Set Bosch 2609255029 6 pcs Metal

The Bosch 2609255029 6 pcs Metal drill bits set is designed for precise drilling in metal materials. The set contains six cylindrical-shank bits in diameters 2.0, 3.0, 4.0, 5.0, 6.0 and 8.0 mm, offering a compact selection for common metalworking tasks. Manufactured to Bosch quality standards, these bits are suitable for handheld drills and drill presses where a cylindrical shank is required.

Advantages

These drill bits provide consistent hole accuracy and edge retention during metal drilling. The cylindrical shank ensures secure clamping in standard chucks, and the variety of diameters covers small to moderate hole sizes without the need to change tool types. The set’s construction focuses on wear resistance and dependable performance for repeated use on steel, iron and other common metals.

• Typical applications: through-holes, pilot holes and fastening preparation

How to use

Select the appropriate diameter for the required hole, secure the drill bit in the chuck ensuring correct alignment of the cylindrical shank, and set the drill speed according to the metal type and bit diameter. Use cutting fluid when drilling harder metals to reduce heat and prolong bit life. Apply steady, moderate pressure and withdraw periodically to clear chips and prevent clogging.

Usage recommendations

For best results, start with a lower speed for larger diameters and harder materials, use appropriate cutting lubrication, and inspect bits for wear before prolonged use. Replace damaged or worn bits to maintain hole quality and operator safety.
