## Summary description

Cylindrical HSS drill bit by GRAPHITE, 9 mm diameter (model 55H031), designed for drilling metal. Made from high-speed steel (HSS) for wear resistance and heat tolerance, suitable for handheld drills and drill presses. Ideal for creating clean through-holes in steel, iron and non-hardened metal sheets in workshop and maintenance tasks.

## Long description

GRAPHITE HSS cylindrical drill bit, 9 mm diameter, model 55H031, is designed for drilling holes in metal. Made of high-speed steel (HSS), the bit provides wear resistance and maintains cutting performance at elevated temperatures. Its cylindrical shank fits most chucks on handheld drills and drill presses, enabling stable rotation and reliable hole making in steel, iron and non-hardened metal sheets for workshop and maintenance tasks.
Advantages
The HSS material offers improved hardness and heat tolerance compared with carbon steel, reducing wear during prolonged drilling in metal. The cylindrical shank ensures compatibility with standard drill chucks and facilitates quick mounting. The 9 mm diameter produces precise through-holes while the geometry of the cutting edges is optimized for efficient chip evacuation and smoother drilling in typical metalworking applications.
Suitable for
 Drilling through steel and iron sheets and plates
 Creating mounting or clearance holes in maintenance and repair work
 General-purpose metalworking in workshops and on-site service
Key specifications
 Material: high-speed steel (HSS)
 Shank type: cylindrical
 Drill diameter: 9 mm
 Recommended use: drilling through metal and non-hardened steel
 Compatibility: handheld drills and drill presses with standard chucks
How to use
Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the shank is fully inserted and tightened. Mark the drilling position and, when possible, use a center punch to prevent wandering. Start drilling at low speed to establish a pilot groove, then increase speed appropriate for the metal thickness and tool capability. Apply steady pressure without forcing the bit; allow the bit to cut and remove heat. For thicker or harder metal, use cutting fluid or coolant to extend tool life and improve chip evacuation. After finishing, retract the bit while the drill is running slowly to clear chips, then stop and remove the bit.
Usage recommendations
 Use appropriate personal protective equipment such as safety glasses and gloves, clamp workpieces securely, and choose drill speeds and cutting fluids suitable for the metal being drilled to maximize bit life and hole quality.
