لقم الثقب (Bosch) المصنوعة من الفولاذ سريع القطع قطر (3.5mm) للمعادن ذات السماكة (39mm) (2-608-595-058)

DIN 338 is a standardized specification for twist drill bits. It ensures consistent diameter, tolerance, flute geometry, and shank compatibility across DIN-compliant bits, so the 3.5 mm bit will fit standard chucks and produce predictable hole sizes.

You can drill into metal, steel, and various non-ferrous metals. Its HSS-G construction and precision tip are optimized for durable, accurate drilling in metallic workpieces.

Key specs include: High-Speed Steel (HSS-G) construction for wear resistance, precision ground tip for accurate holes, DIN 338 standard, 3.5 mm diameter, corrosion-resistant coating for longer tool life, and a pack quantity for convenient replacement.

Insert the bit shank into the drill chuck and tighten securely to remove play. Use appropriate drilling speed for metal (start with moderate RPM), apply steady pressure, and keep the bit cool with light lubrication or cutting fluid to minimize heat buildup and prolong bit life.

HSS-G offers good wear resistance, toughness, and heat tolerance for metal drilling. It maintains a sharp edge longer than standard carbon steel bits and helps achieve cleaner holes with reduced wandering.

Keep bits cool with cutting fluid or light lubrication, avoid excessive feed pressure, clean residue after use, store in a dry environment to prevent corrosion, and use the bit only for its intended metal materials to minimize wear.

Wear eye protection and gloves, secure the workpiece, ensure the drill is stable, start with a pilot hole if needed, and use appropriate speed and feed. Let the bit do the work and avoid overheating the tool and workpiece.

Compared to other 3.5 mm HSS-G DIN 338 bits on Fepy, you’ll typically see differences in coating, brand reputation, and flute geometry.

Ideal for metal fabrication, automotive repairs, electronics enclosures, and DIY metal projects where precise, small-diameter holes are needed in metal sheets, plates, or components.

The bit is sold per pack as a 3.5 mm HSS-G DIN 338 drill bit. It is designed to fit standard drill chucks that accept DIN 338 bits, so you should check your chuck’s compatibility with a 3.5 mm shank and ensure proper clamping to avoid slippage.

Yes. Its DIN 338-standard dimensions, HSS-G construction, and corrosion-resistant coating make it appropriate for professional metalworking tasks as well as home workshop projects requiring reliable, precise drilling in metal.
