Vrták Bosch 2 608 594 254 pilotní

The Bosch pilot drill bit 2 608 594 254 (HSS G) is a replacement pilot bit designed for use with hole saws and for making centre holes prior to further machining. With a 7.15 mm diameter and HSS G tip geometry, the bit offers improved guidance, greater robustness and higher drilling speed and lifetime compared with the previous design. It is supplied in blister packaging for convenient storage and handling and is suitable for a wide range of materials.

Advantages

The HSS G tip geometry and larger diameter provide greater durability, improved guidance while drilling and up to three times longer lifetime and faster drilling. The bit produces accurate centre holes that help stabilise hole saws and other cutting tools. Its construction is suitable for use on a variety of materials, reducing the need to change tools frequently.

Suitable for (tasks / use cases)

• Drilling centre holes for hole saws
• Precision pilot drilling in wood and drywall
• Drilling in plastics and non-ferrous metals
• Pilot drilling in metal and stainless steel
• DIY and professional applications requiring accurate guidance

How to use

Fit the pilot bit in the chuck of a compatible drill or rotary tool and ensure it is tightened securely. Use the pilot bit to drill a centre hole at the marked position; the improved tip geometry will help maintain accurate guidance. For hole-saw operations, use the pilot hole to stabilise the saw before cutting. Select appropriate speed and cutting parameters for the work material and apply steady, moderate pressure to avoid overheating.

Recommendations

For best results, choose drilling speeds and feed consistent with the material being worked (lower speeds for stainless steel, higher for wood), use cutting lubricant when drilling metals, and replace the bit when wear affects guidance or cutting performance.
