Drill bit for metal Smart HSS cylindrical 4.5 mm 10 pcs

Smart HSS cylindrical drill bits for metal, 4.5 mm diameter, pack of 10 pieces, are high-speed steel tools designed for drilling consistent, clean holes in ferrous and non-ferrous metals. The cylindrical shank fits standard chucks and is suitable for workshop drills and drill presses. These drill bits provide a reliable cutting edge and dimensional stability for routine metalworking and repair tasks.

Advantages

Manufactured from HSS (high-speed steel), these drill bits retain hardness at elevated temperatures and offer good wear resistance during repeated metal drilling operations. The cylindrical shank ensures compatibility with a wide range of standard chucks and simplifies bit changes. Supplied as a 10-piece set, the pack gives spare tools for continuous work and reduces downtime from breakage or dulling.

Подходит для

• Сверление углеродистой и легированной стали
• Работа с алюминием и другими цветными металлами
• Мастерские и бытовой ремонт
• Сверлильные станки и переносные дрели
• Серийное и разовое сверление с требованием стабильного диаметра отверстия

Key specifications

• Material of cutting part: high-speed steel (HSS)
• Diameter: 4.5 mm
• Shank type: cylindrical shank for standard chucks
• Quantity: 10 pieces per pack
• Intended materials: ferrous and non-ferrous metals
• Typical applications: hand drills and drill presses for metalworking

How to use

Secure the drill bit in the drill chuck and tighten firmly to prevent wobble. Select an appropriate spindle speed for the material being drilled (slower speeds for harder steels, higher speeds for softer non-ferrous metals) and use cutting lubricant when drilling steel to reduce heat and extend tool life. Apply steady pressure, back out occasionally to clear chips, and maintain perpendicular alignment for precise, round holes. Replace bits from the pack when wear or chipping affects hole quality.

Usage recommendations

For best performance when drilling thicker or harder steel, use a cutting fluid and moderate feed rate to avoid overheating. When drilling aluminium or other soft metals, increase speed and ensure chip evacuation to prevent clogging. Store the bits dry and organized to protect cutting edges and keep spares ready for ongoing workshop work.
