Drill bit set MODECO HSS cylindrical for metal 7 mm, 10 pcs (MN-60-270)

Set of 10 MODECO HSS cylindrical shank drill bits for metal with 7 mm diameter. Manufactured from high-speed steel (HSS), these drill bits are intended for drilling steel and other metallic materials. The cylindrical shank design fits standard chucks and is suitable for workshop, maintenance and metalworking tasks requiring precise 7 mm holes. This set provides uniform geometry across bits to ensure consistent hole quality and repeatable performance in general metal drilling applications.

Advantages

High-speed steel (HSS) construction offers good hardness and wear resistance at typical drilling temperatures, while the cylindrical shank ensures compatibility with most drill chucks and holders. A uniform 7 mm diameter across all ten bits simplifies drill selection for repetitive tasks. The set format reduces downtime by providing immediate replacements when individual bits become worn or damaged. The geometry is optimized for general-purpose metal drilling, balancing cutting efficiency and hole finish.

Suitable for

• Drilling through mild and alloy steels
• Workshop and maintenance drilling operations
• Metal fabrication and repair tasks
• Preparing holes for bolts, rivets or fasteners in metal parts

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Drill diameter: 7 mm
• Quantity: 10 pieces per set
• Intended use: Metal drilling

How to use

Secure the selected 7 mm HSS drill bit in a compatible drill chuck, ensuring proper clamping and alignment. Use appropriate cutting fluid or coolant when drilling steel and harder alloys to reduce heat and extend tool life. Begin drilling at low to moderate speed, applying steady axial pressure; adjust speed according to material hardness and drill condition. Withdraw the bit periodically to clear chips and prevent clogging. After use, clean chips from the flutes and store the bits in their container or a dry, protected location to avoid corrosion.

Usage recommendations

For best results when drilling steel, use cutting fluid and a drill speed appropriate for a 7 mm HSS bit in metal (moderate RPM). Replace worn bits to maintain hole accuracy and reduce the risk of workpiece damage.
