Material Features: This is real High Speed Steel (HSS) — not cheap tool steel. Packed with tungsten, molybdenum, chromium & vanadium. Hardness? HRC61–67. Even at 600°C, it stays sharp. Surface is smooth, no cracks — ready to machine, no extra grinding needed. Why It’s Efficient: Drill, mill, or punch copper, aluminum, or soft steel like butter. Lasts 3–5x longer than ordinary steel. Cut faster. Change tools less. Save time. Save money. Perfect for workshops, CNC shops, and serious DIYers who want to maximize output. Must-Know Tips: ✅ Wipe dry after use ✅ Coat with mineral oil for long-term storage — it’s your rust shield. ✅ Avoid salt, vinegar, juice — acids eat HSS fast. ✅ Use coolant when grinding — dry grinding = cracked edges. ✅ Wear safety glasses & gloves — flying chips are no joke.
