Drill bit for metal Smart HSS cylindrical 6 mm set of 10 (mpn 24-060)

Set of ten Smart HSS cylindrical drill bits, 6 mm diameter, designed for drilling through steel and other ferrous and non-ferrous metals. The bits are made from high-speed steel (HSS) to provide wear resistance and cutting performance in typical workshop and maintenance applications. Cylindrical (straight) shanks ensure compatibility with standard drill chucks and portable drills, making the set suitable for fabrication, repair and precision metalworking tasks that require clean, round holes.

Advantages

High-speed steel construction offers a balance of hardness and toughness for general-purpose metal drilling. The 6 mm diameter is a common size for bolts and dowels, providing predictable hole dimensions. Cylindrical shanks fit conventional chucks without adapters, simplifying tool changes. Supplied as a set of ten, the pack reduces downtime by keeping replacements on hand for repetitive or multiple-site jobs.

Suitable for

• Drilling holes in mild and medium carbon steel
• Work with stainless steel and non-ferrous metals (with appropriate feed and speed)
• Workshop fabrication, repair and maintenance tasks
• Portable and bench drilling where a 6 mm hole is required

Key specifications

• Material: High-speed steel (HSS)
• Drill diameter: 6 mm
• Shank type: Cylindrical (straight shank) compatible with standard chucks
• Quantity: Set of 10 drill bits
• Typical applications: Metal drilling for fabrication and maintenance

How to use

Secure the drill bit in the drill chuck and tighten firmly to prevent slippage. Select an appropriate spindle speed and feed rate for the metal being drilled—lower speeds and steady pressure for harder alloys, higher speeds for softer non-ferrous metals. Use cutting fluid or lubricant when drilling steel to reduce heat and extend bit life. Back the drill out periodically to clear chips and prevent clogging of the flutes. After use, clean and store the bits in their case to avoid corrosion and maintain tip geometry.

Usage recommendations

For best results, start with a center punch to locate the hole and reduce bit wandering. When drilling stainless steel or harder alloys, use reduced speed and increased coolant; for softer metals, moderate speed and steady feed give the best balance of finish and tool life.
