لقم مثقب بوش المعدنية المصنوعة من الفولاذ سريع القطع قياس (2.5X30X57mm) تباع (علبة من 10 قطع)

Specifications: 2.5 mm diameter, 57 mm total length, 30 mm flute length, HSS construction, and a pack of 10 bits. The design emphasizes precision twist cutting for smooth metal drilling.

Compared to standard low-cost bits, this HSS twist bit offers better heat resistance and longer life under metalworking conditions.

Use cases include drilling small, precise holes in metal components, electrical panels, aluminum profiles, and hardware assemblies. It can also handle light-duty drilling in wood and plastic when a small hole is needed.

Insert the bit into a drill chuck, tighten securely, and set a moderate speed appropriate for metal. Apply steady pressure without forcing the bit, and consider using cutting oil or lubricant to reduce heat and extend life. Keep the workpiece clamped to avoid movement.

Yes. Wear eye protection, clamp your workpiece, secure the drill, and avoid overheating the bit. Let the bit do the cutting with steady feed, and stop if the drill binds or binds to prevent breakage.

It’s optimized for metal drilling (like mild steel and aluminum) and can handle wood and plastic for small-diameter holes, though metal work is its primary strength.

Clean off chips after use, store them in their original pack or a labeled bit organizer to prevent dulling or rust, and avoid overheating by using proper lubrication and moderate drilling speeds.

Yes, a 10-pack provides a ready supply for ongoing metalworking tasks, reducing the need for frequent replacements and ensuring you have spares for different projects.

Begin with a light, steady plunge to create a small pilot mark, then gradually increase feed pressure while maintaining perpendicular alignment to the work surface for clean, centered holes.

HSS bits like this one offer good heat resistance and general-purpose performance for metal and other materials. Cobalt or TiN-coated bits typically last longer under heavy metal drilling and extreme heat but may be more expensive and specialized for tough alloys.
