## Summary description

Luna HSS cylindrical drill bit set for metal, model 209540103, containing assorted diameters from 1.5 mm to 10 mm. High-speed steel (HSS) construction provides durability and heat resistance for drilling into various metal materials. Suitable for workshop, maintenance and fabrication tasks requiring precise metal drilling with hand drills or drill presses.

## Long description

Luna HSS cylindrical drill bit set for metal contains assorted straight-shank drill bits in diameters from 1.5 mm up to 10 mm. Manufactured from high-speed steel (HSS), the set is designed for drilling holes in a variety of metal materials using hand-held drills or drill presses. The cylindrical shank ensures compatibility with standard chucks and steady, concentric rotation for precise hole making.
Advantages
The HSS material offers good hardness and heat resistance for metalworking operations, reducing wear during repeated drilling. The assortment of diameters covers common hole sizes needed in maintenance, fabrication and assembly work, which minimizes the need to change tools frequently. The straight cylindrical shank fits standard chucks and simplifies mounting in both portable drills and bench machines.
Suitable for
 Drilling holes in mild steel, stainless steel, aluminium and other common metals
 Workshop maintenance, mechanical repairs and small fabrication projects
 Use with hand drills, drill presses and portable drilling units
 Applications requiring a range of hole diameters from 1.5 mm to 10 mm
When it may not be suitable
This HSS cylindrical set is intended for general-purpose metal drilling; it may not be optimal for very hard alloy steels, cast iron with high hardness, or abrasive non-metal materials where specialized coatings or carbide tips are required. For production drilling at high speed or extended continuous use, drills with specific coatings or carbide grades can offer longer life.
Key specifications
 Material: High-speed steel (HSS)
 Shank type: Cylindrical (straight shank) compatible with standard chucks
 Diameter range: 1.5 mm to 10 mm (assorted sizes within this range)
 Intended use: Drilling metal materials
How to use
Select the drill bit with the required diameter and secure it firmly in the drill chuck. Use appropriate cutting speed and feed for the metal being drilled: lower speeds for harder steels and higher speeds for softer metals like aluminium. Apply cutting fluid or coolant when drilling steel to reduce heat and extend tool life. Start with a center punch on the workpiece to prevent walking, clamp the workpiece securely, and drill with steady pressure. Withdraw the bit periodically to clear chips when drilling deeper holes.
What to consider before purchase
 Verify that the diameter range covers the hole sizes you need (1.5 mm–10 mm)
 Confirm compatibility of the cylindrical shank with your drill chuck
 Consider material thickness and type to determine if HSS is appropriate or if coated/carbide tools are required
 Check whether you need additional accessories such as cutting fluid, center punches or clamping equipment
Usage recommendations
Use appropriate spindle speeds and cutting fluid to prolong drill life; begin holes with a center punch and steady feeds, and match speed to material hardness. For repeated or heavy-duty drilling in hard alloys, consider drills with special coatings or carbide grades.
