Drill bit Bosch 8 mm HSS model 2608680289 for metal and wood

Bosch 8 mm HSS drill bit model 2608680289 is a high-speed steel twist drill designed for drilling clean, accurate holes in metal and wood. The 8 mm diameter and HSS material provide a combination of wear resistance and heat tolerance for routine workshop, installation and repair tasks. It is suitable for use in hand-held electric drills and drill presses and is intended for general-purpose metalworking and wood-working applications where consistent hole quality is required.

Advantages

The HSS construction ensures improved hardness and better heat resistance compared with ordinary carbon-steel bits, allowing longer life under typical drilling conditions. The twist-flute geometry supports efficient chip evacuation when drilling through metal and wood, reducing clogging and maintaining cutting performance. The 8 mm diameter offers a common size for fasteners and dowels, simplifying selection for everyday repair and installation work. The bit is compatible with standard drill chucks and provides stable concentricity for accurate hole placement.

Подходит для

• Сверление стальных и цветных металлов
• Сверление древесины и деревянных заготовок
• Монтажные и ремонтные работы
• Работа с ручными дрелями и сверлильными станками

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 8 mm
• Flute type: Twist / two-flute
• Intended materials: Metal and wood
• Usage: General-purpose drilling

How to use

Secure the drill bit in the chuck of a hand-held drill or drill press, ensuring it is tightly clamped and centered. Select a drill speed appropriate for the material: moderate to high speeds for wood and lower speeds for harder metals. Mark the drilling point, use a center punch for precise placement when drilling metal, and apply steady axial pressure while keeping the drill perpendicular to the surface. For metal, withdraw the bit periodically to clear chips and allow cooling; for prolonged metal drilling use light cutting lubricant to reduce heat and wear. After use, clean the bit of debris and store it in a dry place to prevent corrosion.

Рекомендации по использованию

Для длительного срока службы соблюдайте рекомендованные скорости сверления и применяйте смазку при обработке твёрдых металлов. При сверлении древесины следите за отсутствием излишнего нагрева и проверяйте зазор в патроне для минимизации биения.
