Drill bit FANAR HSS cylindrical 11 mm – metal drilling, solid HSS construction

FANAR HSS cylindrical 11 mm drill bit is designed for drilling metal, offering a solid high-speed steel construction for consistent cutting performance. The cylindrical shank fits standard drill chucks and drill presses that accept straight shanks. This 11 mm diameter drill bit is intended for accurate hole-making in a range of ferrous and non-ferrous metals in workshop, maintenance and fabrication settings.

Advantages

The drill bit’s HSS (high-speed steel) composition provides good wear resistance and heat tolerance compared with standard carbon steel bits, ensuring longer tool life during metal cutting. Its solid one-piece design delivers reliable concentricity and reduced vibration when used with compatible drills, allowing for precise 11 mm holes. The cylindrical shank ensures easy mounting in common chucks and steady performance in drill presses and hand drills.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminium and other non-ferrous metals
• Workshop metalworking and fabrication tasks
• Maintenance, repairs and component assembly requiring 11 mm holes
• Use with drill presses and hand drills that accept cylindrical shanks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank
• Cutting diameter: 11 mm
• Construction: solid one-piece drill bit
• Intended material: ferrous and non-ferrous metals

How to use

Select an appropriate drill and chuck that securely clamp a cylindrical shank. Mark and center-punch the drilling point on the workpiece to reduce wandering. Use suitable cutting fluid or coolant when drilling harder metals to reduce heat and improve chip evacuation. Start at a low speed to establish the hole, then increase speed within the drill’s and bit’s recommended range for the material. Apply steady, even pressure and clear chips periodically to maintain cutting efficiency and prolong tool life.

Usage recommendations

For best results when drilling metal, use cutting oil or coolant, clamp the workpiece securely, and avoid excessive feed pressure that may overheat or dull the HSS cutting edges. Re-sharpen or replace the bit if signs of wear or chipping appear to maintain hole quality and operator safety.
