Drill bit for metal Forsage 4.5 mm HSS, 2 pieces

Forsage 4.5 mm HSS drill bits, pack of 2, are high-speed steel tools designed for drilling precise holes in mild steel, ferrous and non-ferrous metals, and common metal alloys. Each bit has a 4.5 mm diameter and a standard twist design suited for both hand drills and drill presses, providing consistent hole size and clean entry on sheet and plate materials used in metalworking, repair, and fabrication tasks.

Advantages

High-speed steel construction provides a balance of hardness and toughness for reliable performance when cutting metal. The 4.5 mm diameter ensures uniform hole sizing where this specific dimension is required. The pair format gives immediate replacement or spare for continued work without interruption. The twist geometry and polished shank improve chip evacuation and reduce walking at start-up under appropriate pilot techniques.

Suitable for

• Drilling holes in mild steel sheets and plates
• Creating pilot or through-holes in ferrous and non-ferrous metals
• Maintenance, repair, and fabrication tasks requiring 4.5 mm holes
• Use with handheld drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 4.5 mm
• Quantity: 2 pieces per pack
• Tip style: standard twist point suitable for general metal drilling
• Compatibility: for use in handheld electric drills and drill presses

How to use

Secure the workpiece and mark the drilling position. Use appropriate clamping to prevent movement. Select the correct drill chuck holding the 4.5 mm HSS bit and ensure it is tightened firmly. Begin drilling at low to moderate speed for metal, applying steady pressure and allowing the bit to cut without forcing. Use cutting fluid or lubricant for improved cutting life and chip flow, especially when drilling harder steels. Withdraw the bit occasionally to clear chips and cool the cutting edge.

Usage recommendations

For best results, pre-drill pilot holes when working with thicker plates, use appropriate cutting lubricant, and adjust drill speed to material hardness—lower speeds for harder steels and moderate speeds for softer metals. Replace bits showing wear or loss of cutting edge to maintain hole quality and tool safety.
