Drill bit for metal Smart HSS cylindrical 6.5 mm set 10 pcs (11-065)

Set of 10 Smart HSS cylindrical drill bits with a 6.5 mm diameter designed for drilling steel and other metallic materials. Manufactured from high-speed steel (HSS), these bits offer wear resistance and maintain hardness at elevated temperatures encountered during metal drilling. The cylindrical shank is compatible with standard chucks used in hand drills and drill presses, providing reliable clamping and straightforward tool changes for workshop, maintenance and metalworking tasks that require precise 6.5 mm holes.

Advantages

High-speed steel construction ensures durability and resistance to heat-related softening during continuous drilling operations. The 6.5 mm diameter is produced to consistent tolerances for repeatable hole size. Cylindrical shanks provide universal compatibility with common drill chucks, enabling fast replacement and stable running. Supplied as a set of 10 pieces, the package reduces downtime by providing spare bits for routine workshop and maintenance work.

Suitable for

• Drilling holes in mild and alloy steels
• Metal fabrication and assembly work
• Workshop maintenance and repair tasks
• Preparation of holes for tapping or fastening
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 6.5 mm
• Shank type: cylindrical (straight)
• Quantity in set: 10 pieces
• Intended application: drilling in metallic materials (steel and alloys)

How to use

Secure the selected 6.5 mm bit in the drill chuck and tighten firmly to prevent slippage. Select an appropriate cutting speed and feed rate for the metal being drilled; reduce speed for harder alloys to limit heat buildup. Apply steady pressure and, if possible, use cutting fluid or lubricant to improve chip evacuation and extend tool life. Clear chips from the hole periodically and allow the bit to cool if operating continuously to avoid premature wear.

Usage recommendations

For best results when drilling steel, use a cutting lubricant, start with a pilot hole if drilling larger assemblies, and ensure the drill is aligned perpendicular to the workpiece to achieve accurate 6.5 mm holes and prolong bit life.
