## Summary description

Set of GRAPHITE HSS drill bits with titanium coating for drilling metal. The set (MPN 57H198) includes assorted diameters ranging from 1.5 mm to 6.5 mm (listed sizes within product name). Designed for use with hand drills and drill presses, these cylindrical-shank bits provide wear resistance from the Ti coating and are suitable for steel, non-ferrous metals and general metalworking tasks in workshops and maintenance.

## Long description

Set of GRAPHITE HSS drill bits with titanium coating for metal, assorted diameters from 1.5 mm to 6.5 mm. These bits have cylindrical shanks and are made from high-speed steel (HSS) with a titanium surface layer that increases wear resistance and reduces friction during drilling. The set is intended for use in hand drills and drill presses and is suitable for drilling steel, cast iron, aluminium and other non-ferrous metals in workshop, maintenance and hobby applications.
Advantages
Titanium coating extends the life of the cutting edges and improves heat resistance compared with uncoated HSS bits. Cylindrical shanks ensure secure clamping in standard drill chucks. The assortment of diameters from 1.5 mm to 6.5 mm covers a wide range of common hole sizes, reducing the need to buy individual bits. These bits deliver reliable performance for general metalworking tasks while maintaining consistent hole quality.
Suitable for
 Drilling holes in steel and cast iron
 Working with aluminium and other non-ferrous metals
 Workshop repairs and maintenance tasks
 Use with hand drills and small drill presses
 Hobby and DIY metal projects
Key specifications
 Material: high-speed steel (HSS)
 Coating: titanium surface layer for improved wear resistance
 Shank type: cylindrical shank compatible with standard chucks
 Diameter range: 1.5 mm to 6.5 mm (assorted sizes)
 Intended use: metal drilling (steel, non-ferrous metals)
How to use
Select the appropriate diameter from the set for the required hole size and clamp the bit securely in the drill chuck. Use appropriate drill speed for the material being drilled—lower speeds for hard steels and higher speeds for softer metals such as aluminium. Apply steady feed pressure and keep the drill perpendicular to the work surface to maintain hole accuracy. Use cutting fluid or lubricant when drilling hard materials to reduce heat and prolong bit life. After use, clean chips from the flutes and store the bits in their case to prevent damage and corrosion.
Usage recommendations
For best results, pre-center holes with a center punch when drilling sheet or plate to prevent walking. Start with a pilot hole when drilling large or deep holes and use light, consistent pressure. Replace bits that show significant wear, chipping or loss of cutting performance to avoid workpiece damage. Always follow safety practices: wear eye protection and secure the workpiece before drilling.
