Bosch 2 608 594 255 broca piloto

The Pilot Drill Bit Bosch 2 608 594 255 is a high-speed steel (HSS G) pilot bit designed for precise guidance of hole saws and for drilling centre holes. With a diameter of 7.15 mm and packaging suitable for rotary hammer applications, it offers improved durability and accurate guidance across a range of materials.

Advantages

The HSS G geometry and enlarged diameter increase robustness and extend service life compared with its predecessor, providing up to three times higher speed and longer lifetime thanks to the optimized tip design. The bit delivers improved guidance for more accurate hole placement and can be used for centre-hole preparation before using hole saws.

Suitable for

• Wood
• Drywall
• Plastics
• Metal and non-ferrous metals

How to use

Fit the pilot drill bit into a compatible rotary hammer or drill chuck designed to accept this shank type. Mark the centre point of the hole, position the bit firmly, and drill at a controlled speed ensuring correct alignment. Use the pilot hole to guide hole saws or to create precise centre holes. Apply appropriate cutting speed and feed for the material being drilled and avoid excessive side loading to preserve tip geometry.

Recommendations

Use appropriate personal protective equipment and clamp workpieces when possible. For metals and stainless steel, use cutting fluid or reduced speed to extend bit life. Replace the bit when wear affects guidance or cutting performance.
