Drill bit set MODECO HSS cylindrical for metal 4.5 mm, 10 pieces MN-60-445

Set of 10 MODECO HSS cylindrical drill bits, each with a 4.5 mm cutting diameter, designed for drilling metal. Made from high-speed steel (HSS) to provide wear resistance and maintain sharpness when working with a range of ferrous and non-ferrous metals. The cylindrical shank fits standard drill chucks, allowing use with hand drills and drill presses in workshop, maintenance, and fabrication environments where precise, repeatable holes are required.

Advantages

The high-speed steel composition delivers a balance of hardness and toughness for drilling through thin sheet metal, structural steel, and non-ferrous metals with reduced risk of premature dulling. The uniform 4.5 mm diameter across all ten pieces ensures consistent hole size for batch operations and repairs. The cylindrical shank provides compatibility with common chucks and quick mounting, while the set format supplies multiple spare bits to minimize downtime during projects.

Suitable for

• Drilling holes in thin sheet metal and metal panels
• General workshop and maintenance drilling tasks
• Fabrication and metalworking projects requiring 4.5 mm holes
• Repair and retrofit work on machinery and metal structures

Key specifications

• Drill type: twist drill bits for metal
• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Diameter: 4.5 mm
• Quantity: 10 pieces

How to use

Select a drill speed and feed appropriate for the metal being drilled; lower speeds are recommended for harder steels and higher speeds for softer, non-ferrous metals. Secure the workpiece to prevent movement and center-punch the drill location to reduce wandering. Mount the cylindrical shank securely in the drill chuck and use steady pressure, allowing the bit to cut without forcing. For deeper holes or tougher materials, periodically withdraw the bit to clear chips and reduce heat buildup. Apply cutting fluid or lubricant when drilling steel to extend bit life and improve hole quality.

Usage recommendations

Use a suitable cutting lubricant or coolant when drilling ferrous metals, and replace bits that show significant wear or chipping. Store the set in its original case or a dedicated organizer to protect cutting edges and ensure consistent fit in the chuck.
