Drill bit set for metal GEKO G38231 — titanium-coated 1.5–6.5 mm, 13 pieces

GEKO G38231 is a 13-piece drill bit set designed for drilling metal. The set includes titanium-coated high-speed steel bits in sizes from 1.5 mm to 6.5 mm, covering a range of small to medium diameters suitable for repairs, fabrication and general metalworking. Bits are compatible with handheld drills and drill presses and are intended for cutting into steel, iron, non-ferrous metals and common metal alloys where corrosion-resistant, wear-resistant edges improve tool life.

Advantages

The titanium coating reduces friction and increases surface hardness, which helps extend bit life compared with uncoated high-speed steel. A range of thirteen sizes from 1.5 mm to 6.5 mm provides flexibility for different hole diameters without changing tool types. The set is compact and organised for easy storage and quick selection of the required diameter when working on fabrication, automotive or household metal-drilling tasks.

Suitable for

• Drilling holes in mild and medium-hard steels
• Automotive repair and maintenance tasks
• Metal fabrication and sheet metal work
• Home workshop and DIY metal projects
• Use with handheld drills and drill presses

Key specifications

• Set composition: 13 drill bits
• Material: high-speed steel (HSS) with titanium coating
• Diameter range: 1.5 mm to 6.5 mm
• Intended materials: steel, iron, non-ferrous metals and common metal alloys
• Shank type: straight round shank for standard chucks

How to use

Select the drill bit diameter appropriate for the hole required and secure it in the drill chuck. When drilling metal, clamp the workpiece to prevent movement and use a centre punch to mark the drilling point if precision is needed. Start at low speed to establish the hole, then increase speed as appropriate for the material and bit size. Apply cutting oil or lubricant during drilling to reduce heat and wear on the titanium-coated surface and to prolong bit life. Withdraw the bit periodically to clear chips and allow cooling.

Usage recommendations

Use moderate feed pressure and appropriate rotational speed for the material; reduce speed for harder steels and larger diameters. Maintain lubrication when drilling to maximise bit life, and replace excessively worn bits to avoid poor hole quality and increased risk of bit breakage.
