Drill bit set GEKO G38241, 13 pieces, sizes 1.5–6.5 mm, titanium-coated, plastic storage box

GEKO G38241 is a 13-piece drill bit set that covers sizes from 1.5 mm to 6.5 mm in convenient 0.5 mm or 1.0 mm increments. Each twist drill bit has a titanium coating that improves surface hardness and increases wear resistance compared with uncoated steel bits. The set is supplied in a compact plastic storage box that keeps bits organised and protected during transport and storage. The set is intended for common drilling tasks in wood, plastics and metal sheets where standard HSS twist drill bits are used, suitable for DIY, repair and light professional applications.

Advantages

The titanium coating on the GEKO G38241 drill bits provides enhanced surface durability and reduces friction during cutting, which helps extend bit life under normal conditions. The selection of 13 sizes from 1.5 mm to 6.5 mm covers a wide range of common hole diameters without the need to purchase individual bits. The plastic storage box is lightweight, keeps the bits sorted and protected from damage, and simplifies transport and storage between jobs.

Suitable for

• Drilling wood for furniture assembly and carpentry tasks
• Drilling plastics and composite panels
• Drilling thin metal sheets and light fabrication work
• General DIY and home repair projects
• Light professional use where standard HSS bits with coating are acceptable

• Coating: titanium coating for increased surface hardness and wear resistance
• Material type: high-speed steel twist drill bits (HSS style)
• Storage: plastic storage box with individual bit positions
• Applicable materials: wood, plastics, thin metal sheets

How to use

Select the appropriate drill diameter for the required hole size and secure the workpiece to prevent movement. Fit the selected bit into a compatible drill chuck and tighten securely. Use appropriate drill speed and feed for the material being drilled: lower speeds for metals and higher speeds for wood and plastics. Apply steady pressure without forcing the bit; allow the coating and cutting geometry to remove material efficiently. For metal drilling, use cutting fluid where appropriate. After use, clean chips from the bit and store it in the plastic box to protect the coating and cutting edge.

Usage recommendations

To prolong the service life of the titanium-coated bits, avoid overheating by using correct speeds and intermittent drilling when working with metals, and store the bits dry and clean in the provided box. Replace dull or damaged bits to maintain hole quality and reduce risk to the drill and workpiece.
