Drill bit set, titanium-coated HSS-G, 19 pcs, sizes 1–10 mm

19-piece drill bit set, titanium-coated HSS-G, sizes 1–10 mm. This set contains high-speed steel (HSS‑G) twist drill bits with a titanium nitride (TiN) coating, covering a continuous range of small to medium diameters from 1 mm up to 10 mm. The bits are produced for general workshop and maintenance use and are suitable for drilling metal, wood and plastics. The TiN coating increases surface hardness and improves wear resistance to extend cutting life compared with uncoated HSS bits.

Advantages

The TiN coating provides higher surface hardness and reduced friction during cutting, which helps maintain sharpness and reduces heat buildup. HSS‑G base material offers toughness and edge retention for a variety of materials. The comprehensive range of diameters allows precise selection for pilot holes, fastening, and light to medium drilling tasks. Bits are supplied in a compact organizer for convenient storage and quick size identification.

Suitable for

• Drilling in ferrous and non‑ferrous metals (thin to medium thickness)
• Woodworking tasks requiring clean pilot or clearance holes
• Plastics and composite materials
• General workshop maintenance and repair work
• Preparing holes for screws, bolts and dowels

Key specifications

• Material: high-speed steel (HSS‑G) with titanium nitride (TiN) coating
• Number of pieces: 19
• Diameter range: 1 mm to 10 mm (continuous sizes within set)
• Geometry: standard twist drill flute design for general-purpose drilling
• Finish: gold-colour TiN coating to reduce wear and friction
• Storage: compact organizer case for bit protection and size sorting

How to use

Select the correct drill diameter for the required hole and secure the workpiece to prevent movement. Fit the chosen HSS‑G TiN-coated bit into a compatible drill chuck and tighten securely. Use appropriate drill speed: lower speeds for larger diameters and metal work, higher speeds for small diameters and wood, while avoiding excessive heat. Apply steady feed pressure and clear chips regularly. When drilling metal, use cutting fluid or lubricant to further reduce heat and prolong bit life.

Usage recommendations

For best results, pre-drill pilot holes when installing fasteners in hard materials, keep drill speeds and feed consistent, and store bits dry in their case to protect the TiN coating. Avoid excessive side loads and use appropriate lubrication when drilling metals to maximize life of the coated HSS bits.
