مثقاب فولاذ عالي السرعة (HSS) - عيار سلكي

I've been using these HSS wire gauge drills for some light grey cast iron work, and they hold a sharp edge better than my old bits. The screw machine design helps the chips clear out quickly without binding.

The wider flutes on this drill bit cleared chips perfectly when I was boring through some cast iron. It started cutting cleanly without any binding, and the high speed steel held its edge through a full day of use. Exactly what I needed for precise work on tougher metals.

I needed a bit that wouldn't wander on some cast iron, and these HSS drills bite right in without skipping. The wider flutes clear chips beautifully, keeping the hole clean.
