Set di punte Bosch 0603663A03 — set di punte di ricambio per elettroutensili, MPN 0603663A03

Bosch 0603663A03 replacement drill bit set contains precision-ground bits designed for general drilling tasks in wood, metal and plastic depending on the bit types included. The set is manufactured to match common power drill chucks and maintain drilling accuracy, offering a compact selection for maintenance, renovation and on-site repair work. Materials and flute shapes are selected to provide predictable chip evacuation and consistent hole geometry when used within recommended speeds and feed rates.

Advantages

The replacement drill bit set is made with hardened cutting edges and accurate centering tips to reduce wandering and improve hole accuracy. Bits are finished to resist corrosion and designed for uniform diameter tolerance, which supports interchangeability between drills and accessories. The compact selection combines multiple bit sizes to cover frequent drilling needs while minimising the need to change tools during a job.

Suitable for

• Drilling holes in wood for furniture assembly and carpentry.
• Drilling and pilot holes in metal for fastening and fabrication.
• Creating openings in plastic components for repair and modification.
• General maintenance, renovation and professional onsite tasks.

Key specifications

• Material: hardened and ground tool steel suitable for standard drilling.
• Tip design: precision-centred tips for reduced walking and improved start accuracy.
• Finish: corrosion-resistant surface treatment for longer storage life.
• Compatibility: designed for standard power drill chucks (cylindrical shank sizes typical for handheld drills).
• Application range: intended for use in wood, metal and plastic depending on selected bit size and type.

How to use

Select the appropriate bit size for the required hole, insert the bit securely into the drill chuck and tighten. Use recommended drill speed and steady, even feed pressure to avoid overheating and to maintain hole quality; for metal, begin with a pilot hole if required and apply cutting fluid when appropriate. Keep the bit perpendicular to the workpiece for accurate holes and clear chips periodically to prevent clogging. Replace worn or blunted bits to maintain performance and safety.

Recommendations

Use suitable personal protective equipment such as safety glasses and gloves when drilling. Match drill speed and feed to the material: higher speeds for wood, lower speeds and lubrication for harder metals. Store bits in a dry container to prevent corrosion and inspect bits before use for signs of wear or damage.
