مجموعة ريش الثقب ماكيتا الخاصة بالمعدن قياس (9.5X125mm) المصنوعة من الفولاذ سريع القطع (HSS) و المكونة من (5) قطع موديل (D-06557)

HSS-G stands for High-Speed Steel grade G. This construction provides good wear resistance and toughness for metal drilling, allowing faster cutting, smoother holes, and longer life under heavy use compared with standard carbon steel bits.

Key specs include: 9.5 mm diameter, 125 mm length, five pieces in the pack, High-Speed Steel (HSS) construction, heat-resistant coating, and compatibility with most standard drill machines for metalwork.

These bits are designed for metal drilling and perform well in steel and similar metals. They can handle other non-ferrous and certain alloys, though performance will vary. For best results in steel, use appropriate speed and lubrication.

They're ideal for metal fabrication, automotive repairs, home metalworking projects, and any task requiring deeper, precise holes in metal components thanks to the 125 mm reach.

Use them in a drill or drill press with a compatible chuck. Secure your workpiece, start at a moderate speed, and apply steady pressure. Use cutting oil or lubricant for metal drilling and regularly withdraw to clear chips and prevent overheating.

The 9.5 mm diameter is a common size for medium-to-large holes in metal, and the 125 mm length allows deeper drilling into thicker pieces, reducing the need to flip or re-position the workpiece mid-task.

Keep bits sharp, avoid overheating by using appropriate speeds and lubrication, clean and dry them after use, and store them in a dry place to prevent corrosion. The heat-resistant coating also helps maintain cutting performance over time.

Wear safety goggles and gloves, secure the workpiece, keep hair and clothing away from the drill, and always unplug the tool before changing bits. Use proper lubricant to reduce heat and always monitor for overheating.

This Makita D-06557 set offers a premium HSS-G construction, a 9.5 mm diameter, and a 125 mm length in a pack of five, making it a strong choice for metal drilling. For direct comparisons with other HSS metal bit sets on Fepy, look for sets with the same diameter and length, HSS-G or equivalent steel, and similar coating or longevity features. If you share the exact Fepy product URLs you’re considering, I can tailor the comparison and include direct links to each alternative.

Yes. With five bits in one pack, a consistent 9.5 mm diameter for medium-to-large holes, and a length of 125 mm for deeper drilling, the Makita D-06557 set provides durability and readiness for multiple tasks, delivering good value for both professional and DIY metalworking.
