## Summary description

GRAPHITE HSS-TiN drill bit set for metal, 19-piece range from 1.0 to 10.0 mm. High-speed steel (HSS) bits with titanium nitride (TiN) coating provide improved wear resistance and reduced friction. Suitable for drilling steel and other metals, workshop and maintenance tasks, and manual or machine drilling with standard chucks.

## Long description

GRAPHITE HSS-TiN 1.0–10.0 mm, 19 pcs drill bit set offers a comprehensive range of high-speed steel bits with a titanium nitride (TiN) coating. The set covers diameters from 1.0 mm to 10.0 mm in incremental sizes, enabling versatile drilling tasks in steel and other metals. Designed for use in hand drills and machine spindles with standard chucks, these bits combine HSS core strength with TiN surface hardness to extend service life and maintain cutting performance.
Advantages
The TiN coating increases surface hardness and reduces friction, resulting in improved wear resistance and longer tool life compared with uncoated HSS bits. Precision ground flutes and a standard helix geometry provide stable chip evacuation and consistent hole quality across the size range. The set format supplies a broad diameter selection for general workshop, maintenance and fabrication needs, reducing the need to purchase individual sizes.
Suitable for
 Drilling steel and ferrous metals
 Drilling non-ferrous metals and alloys
 Workshop maintenance and repairs
 Preparation work for fittings and assemblies
 Use in hand drills and drill presses with standard chucks
Key specifications
 Material: High-speed steel (HSS) with titanium nitride (TiN) coating
 Diameter range: 1.0 mm to 10.0 mm
 Number of pieces: 19 drill bits
 Coating purpose: Reduced friction and increased wear resistance
 Application: Metal drilling (steel, non-ferrous metals)
 Shank type: Straight round shank for standard chucks
How to use
Select the correct diameter for the required hole and secure the drill bit in the chuck ensuring it is properly centered and tightened. Use appropriate cutting speeds and feed rates for the metal being drilled; lower speeds for harder steels and higher speeds for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat buildup and extend bit life. Withdraw the bit periodically to clear chips and avoid clogging; when drilling deeper holes, peck drilling can improve chip removal.
Usage recommendations
For best results, match drill speed to material hardness and use a quality cutting fluid for ferrous materials. Inspect bits before use for straightness and intact cutting edges. Store the set in a protective case or organizer to prevent damage to the TiN coating and to keep sizes readily accessible.
