Drill bit set MODECO HSS metal cylindrical bits MN-60-906 — assorted diameters 1.5–6.5 mm

MODECO HSS metal cylindrical drill bit set MN-60-906 contains a range of solid high-speed steel bits for drilling metal and similar materials. The set includes assorted diameters from 1.5 mm to 6.5 mm, covering common small to medium hole sizes used in workshop repairs, fabrication and precision metalworking. These straight-shank bits are compatible with standard hand drills and drill presses and are intended for cutting through sheet metal, plates and other ferrous and non-ferrous metals when used with appropriate speeds and cutting fluids.

Advantages

The bits are manufactured from high-speed steel to provide hardness and wear resistance at elevated cutting temperatures. A straight cylindrical shank ensures secure clamping in chucks and easy interchangeability between tools. The assortment of diameters allows selection of the correct size for precise hole diameters without the need for reaming. The compact set simplifies storage and keeps commonly used sizes available for maintenance and production tasks.

Suitable for

• Drilling holes in sheet metal and thin plates
• Workshop repairs and maintenance
• Small fabrication and assembly work
• Precision hole preparation prior to threading or reaming

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight cylindrical shank for standard chucks
• Diameter range: 1.5 mm to 6.5 mm (assorted sizes)
• Intended materials: ferrous and non-ferrous metals, sheet metal
• Compatible tools: hand drills and drill presses

How to use

Secure the selected drill bit in the drill chuck ensuring concentric clamping. Mark and, if necessary, centre-punch the drilling point to reduce wander. Use recommended spindle speeds for the bit diameter and workpiece material, and apply cutting fluid or lubricant when drilling thicker or tougher metals to extend tool life and improve chip evacuation. Feed the drill steadily without excessive side pressure and clear chips periodically. After drilling, deburr the hole as required.

Usage recommendations

For best results when drilling metal, start with lower speeds for larger diameters and harder materials, and use cutting oil to reduce heat and wear. Replace worn bits to maintain hole quality and safety.
