Drill bit for metal MODECO HSS cylindrical 9 mm set of 5 (MN-60-490)

Set of five MODECO HSS cylindrical drill bits with 9 mm diameter designed for drilling metal. These drill bits are made from high-speed steel (HSS) to provide the hardness and heat resistance required for cutting through a range of ferrous and non-ferrous metals. The cylindrical shank fits standard drill chucks, making the set suitable for hand drills, bench drills and portable drilling machines used in workshops, repair shops and on-site metalworking tasks.

Advantages

The HSS material offers improved wear resistance and elevated temperature tolerance compared with standard carbon-steel bits, enabling consistent drilling performance in repeated operations. The 9 mm diameter is useful for medium-sized holes frequently required in fabrication and maintenance. Cylindrical shanks provide secure clamping in standard chucks and straightforward replacement during work. Supplied as a set of five, the pack reduces downtime by providing spare bits for continuous tasks.

Suitable for

• Drilling holes in steel, stainless steel, aluminium and other non-ferrous metals
• Workshop fabrication and assembly tasks
• Maintenance, repair and overhaul operations
• Portable on-site drilling with hand or cordless drills

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 9 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Pack quantity: 5 drill bits
• Intended use: metal drilling (ferrous and non-ferrous)

How to use

Select the appropriate drill speed and apply cutting fluid or coolant when drilling harder metals to prolong bit life and improve chip evacuation. Secure the workpiece with clamps or a vice to prevent movement, fit the 9 mm cylindrical shank into a compatible chuck and tighten firmly. Start drilling at a moderate speed with steady, even pressure; withdraw periodically to clear chips and reduce heat buildup. Replace bits from the set when wear or bluntness affects cutting performance.

Usage recommendations

For best results, use suitable cutting lubricant, choose drill speeds according to the metal type (lower speeds for stainless steel), and ensure the drill and workpiece are securely fixed. Inspect bits before use and replace damaged or excessively worn bits to maintain safe and accurate drilling.
