Drill bit set GEKO titanium-coated cylindrical 1.5–10 mm assorted sizes

GEKO titanium-coated cylindrical drill bit set covers a practical range of metric sizes from 1.5 mm to 10 mm for common drilling tasks. The set includes a selection of diameters—1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7.5, 8, 8.5, 9, 9.5 and 10 mm—designed to fit standard chucks and handheld drills. Titanium coating on the cutting flutes increases surface hardness and reduces friction, which helps extend tool life and maintain cutting performance across repeated use in metal, wood and plastic materials.

Advantages

The titanium coating improves wear resistance and reduces heat buildup during drilling, enabling longer service life compared with uncoated bits for routine workshop and construction tasks. A broad assortment of metric sizes in one set removes the need to purchase individual bits for common diameters, simplifying tool selection. Cylindrical shanks are compatible with most drill chucks and provide stable clamping for accurate holes in a range of materials.

Suitable for

• Drilling holes in mild steel, aluminium and other metals (with appropriate speeds and lubrication)
• Woodworking tasks including cabinetry, shelving and fixture installation
• Plastic and composite materials used in hobby, repair and assembly work
• General workshop and construction drilling where a variety of hole sizes is required

Key specifications

• Drill bit type: twist drill bits with titanium coating
• Shank shape: cylindrical shank compatible with standard chucks
• Diameter range: 1.5 mm to 10 mm in multiple metric increments
• Material compatibility: suitable for metal, wood and plastics
• Finish: titanium coating for improved hardness and reduced friction

How to use

Select the required diameter for the task and secure the bit in the drill chuck, ensuring it is centered and tightened. Use appropriate drill speeds for the material being drilled: lower speeds and cutting fluid for metals, higher speeds for softer woods and plastics. Apply steady, moderate pressure and clear chips frequently to avoid overheating. After use, wipe the bits clean and store them dry to preserve the titanium coating and prevent corrosion.

Usage recommendations

For metal drilling, use cutting fluid and reduced speed to prolong bit life; for wood and plastics, use higher spindle speeds and a backing support when drilling thin sheets to prevent splintering.
