Drill Bit Set MODECO HSS cylindrical for metal 6.5 mm, 10 pcs (MN-60-465)

Set of MODECO HSS metal drill bits with cylindrical shanks, diameter 6.5 mm, 10 pieces. These bits are manufactured from high-speed steel (HSS) and are intended for drilling steel and other ferrous and non-ferrous metals. The cylindrical shank design fits standard drill chucks used in handheld drills and drill presses, offering reliable concentricity and straightforward mounting. The set is appropriate for metalworking, maintenance and fabrication tasks where a 6.5 mm hole is required.

Advantages

HSS construction ensures elevated hardness and improved wear resistance compared with general-purpose carbon steel bits, maintaining sharpness during repetitive metal drilling. The cylindrical shank allows secure clamping in most standard chucks and simplifies bit changes. Supplied as a set of 10 identical bits, it provides work continuity and quick replacement in case of wear or breakage. The 6.5 mm diameter is a common size for through-holes, clearances and pilot operations in mechanical assembly.

Suitable for

• Drilling holes in mild steel, stainless steel and other metal sheets
• Use with handheld electric drills and corded/cordless drills with compatible chucks
• Use on drill presses and pillar drills for controlled depth and alignment
• Maintenance, repair and fabrication tasks in workshops and industrial settings

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank for standard chucks
• Drill diameter: 6.5 mm
• Quantity in set: 10 pieces
• Intended materials: Steel and other metals

How to use

Secure the drill bit in the chuck ensuring concentric clamping and correct alignment. Select appropriate rotational speed and feed rate for the metal being drilled, typically moderate speeds for steel to avoid overheating. Use cutting fluid or coolant when drilling harder metals to extend tool life and improve chip evacuation. Apply steady, even pressure without forcing the bit; retract periodically to clear chips on deeper holes.

Usage recommendations

For best performance, pre-mark and center-punch the drilling point to prevent bit wandering. Match drilling speed and cooling to the specific metal: lower speeds and cutting fluid for stainless steel, moderate speeds for mild steel. Replace worn or chipped bits promptly to maintain hole quality and reduce spindle load.
