## Summary description

Set of GRAPHITE HSS cylindrical drill bits for metal, covering diameters from 1.5 to 6.5 mm. High-speed steel (HSS) construction provides wear resistance suitable for drilling steel and other metal alloys. Cylindrical shank design fits standard chucks and hand drills. Practical for metalworking, maintenance, fabrication and hobby projects requiring small to medium hole sizes.

## Long description

Set of GRAPHITE HSS cylindrical drill bits for metal, covering diameters from 1.5 to 6.5 mm. These high-speed steel (HSS) twist drills are designed for cutting and enlarging holes in steel and common metal alloys. The cylindrical shank fits standard drill chucks and hand drills, providing straightforward mounting and secure grip for manual and light machine operations. The set includes a range of small to medium diameters suitable for precision tasks and general metalworking needs.
Advantages
High-speed steel construction offers good hardness and wear resistance for drilling into steel and similar alloys. Cylindrical shanks ensure compatibility with a wide range of standard chucks and bench or hand drills, simplifying tool changes. The size range from 1.5 to 6.5 mm covers frequent small-to-medium hole requirements, reducing the need to switch between multiple individual bits. The twist-drill geometry provides efficient chip evacuation and stable cutting when used with appropriate speeds and lubrication.
Suitable for
Drilling holes in mild and hardened steel (subject to appropriate cutting speeds and cooling)
General metal fabrication and sheet metal work
Maintenance and repair tasks on machinery and metal assemblies
Hobbyist projects involving metal components and small fittings
Key specifications
Material: high-speed steel (HSS)
Shank type: cylindrical (straight shank) for standard chucks
Diameter range: 1.5 mm to 6.5 mm
Application: drilling in steel and common metal alloys
How to use
Select the drill bit diameter that matches the required hole size, clamp the cylindrical shank securely in the drill chuck, and set the drill to an appropriate speed for the material. For steel and harder alloys, use lower cutting speeds and apply cutting fluid or lubricant to reduce heat and extend drill life. Begin drilling with steady pressure, keeping the drill perpendicular to the workpiece for an accurate hole. Withdraw the bit periodically to clear chips when drilling deeper holes.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves) and secure the workpiece before drilling. For best results on steel, apply cutting oil and maintain moderate spindle speeds; for thin sheet metal, backing the material can reduce burrs and deformation. Inspect bits for wear and replace when cutting performance declines to avoid workpiece damage.
