Drill bit for metal MODECO HSS cylindrical 11 mm set of 10 MN-60-310

Set of ten MODECO HSS cylindrical drill bits for metal, 11 mm diameter. These drill bits are made of high-speed steel (HSS) and feature a straight cylindrical shank designed for standard drill chucks. Intended for drilling steel and other ferrous metals, the set is suitable for workshop, industrial maintenance and DIY metalworking tasks where durable, accurate metal drilling is required.

Advantages

High-speed steel construction provides good hardness and heat resistance for cutting through steel and other ferrous metals. The cylindrical shank ensures compatibility with a wide range of standard drill chucks and straightforward tool changeover. Supplied as a set of ten, the package supports repeated use and reduces downtime by keeping spare bits on hand. The uniform 11 mm diameter allows consistent hole sizing across multiple operations.

Suitable for

• Drilling holes in mild and medium-hard steels
• Workshop and industrial maintenance tasks
• DIY metalworking and fabrication projects
• Pre-drilling for tapping or fastening in ferrous materials

Key specifications

• Material: High-speed steel (HSS)
• Tip type: Standard twist drill geometry for metal
• Shank type: Cylindrical (straight) shank for standard chucks
• Diameter: 11 mm
• Quantity: 10 pieces per set

How to use

Secure the drill bit firmly in a compatible drill chuck, ensuring correct centring on the shank. Mark and clamp the workpiece to prevent movement, then start drilling at low speed to create a pilot groove and reduce wandering. Apply steady pressure and use coolant or cutting oil as appropriate to reduce heat build-up when working with steel. Periodically withdraw the bit to clear chips and inspect the cutting edges; replace the bit when wear or damage reduces drilling performance.

Usage recommendations

Use appropriate cutting fluid for drilling ferrous metals to extend bit life and maintain drilling quality. Match drill speed and feed to material hardness—lower speeds for harder steels—and ensure secure clamping of the workpiece. For threaded preparations, drill the hole to the recommended tapping size for the intended thread.
