## Long description

GRAPHITE HSS cylindrical drill bit set covers diameters from 1.0 mm to 13.0 mm in standard increments and is intended for drilling metal. Manufactured from high-speed steel (HSS), the bits provide the hardness and heat resistance required for cutting ferrous and non-ferrous metals. The set is supplied in a compact organizer that keeps bits sorted and accessible for workshop, maintenance and fabrication tasks.
Advantages
The HSS material ensures good edge retention and higher cutting speeds compared with carbon steel, enabling reliable hole-making in a range of metal materials. Cylindrical shanks allow use in standard chucks and drilling machines without the need for special adapters. The organizer case protects individual bits during storage and transport while making size selection quick and convenient.
Suitable for
 Drilling holes in mild steel, stainless steel, aluminium and other non-ferrous metals
 General workshop and maintenance drilling
 Metal fabrication and repair
 Manufacturing setups that require a range of standard diameters
Key specifications
 Material: High-speed steel (HSS)
 Shank type: Cylindrical
 Diameter range: 1.0 mm to 13.0 mm
 Packaging: Compact organizer case with individual slots
 Typical use: Cutting/drilling in ferrous and non-ferrous metals
How to use
Select the required diameter from the organizer and secure the bit in a properly rated drill chuck. Use appropriate cutting speed and feed for the workpiece material—lower speeds for stainless steel and higher speeds for aluminium. Apply cutting fluid or coolant when drilling harder metals to reduce heat, improve tool life and obtain cleaner holes. Ensure the workpiece is clamped securely and follow standard safety practices including eye protection.
Usage recommendations
To extend tool life and improve hole quality, pre-drill pilot holes for large diameters, use progressive pecking on deep holes to clear chips, and maintain correct coolant application. Store bits in the organizer to prevent damage and keep sizes labelled for quick selection.
