FANAR HSS cylindrical drill bit, 11 mm diameter, designed for precise drilling in various metals. Manufactured from high-speed steel (HSS), this cylindrical-shank drill bit provides consistent cutting performance and wear resistance for workshop, maintenance and industrial metalworking tasks. The straight cylindrical shank fits standard chucks, allowing secure mounting and stable operation when creating through-holes in steel, iron, non-ferrous alloys and other machinable materials.
Advantages
The HSS material ensures elevated hardness and heat resistance, which helps maintain edge sharpness during repeated use and under increased temperatures. The cylindrical shank offers reliable clamping in standard drill chucks and reduces runout for improved hole quality. The 11 mm diameter provides a balance between rigidity and cutting area, suitable for medium-sized hole drilling with controlled chip evacuation in typical metalworking conditions.
Suitable for
- Creating through-holes in steel, iron and non-ferrous metals
- General workshop drilling and maintenance tasks
- Industrial applications requiring repeatable, accurate holes
- Use with hand-held or bench drills equipped with standard chucks
Key specifications
- Material: high-speed steel (HSS)
- Shank type: cylindrical (straight) shank
- Diameter: 11 mm
- Intended use: metal drilling / through-holes
- Compatibility: standard drill chucks and drilling machines
How to use
Secure the 11 mm cylindrical shank firmly in a properly rated drill chuck. Select an appropriate spindle speed and feed rate for the specific metal being drilled—lower speeds for harder steels, higher speeds for softer non-ferrous metals—to reduce heat and wear. Apply steady, moderate pressure and allow the cutting edges to remove material without excessive force. Use cutting fluid or lubricant when drilling steels and alloys to extend tool life and improve surface finish. After drilling, clear chips from the hole before measuring or performing subsequent operations.
Usage recommendations
For best results, match spindle speed, feed and coolant to the workpiece material. Re-sharpen HSS drills when edge wear increases, and inspect the shank and flutes for damage before mounting. Use proper personal protective equipment and secure the workpiece to prevent movement during drilling.
