Drill bit set GEKO G38250 titanium-coated twist bits 13 pcs, sizes 1.5–6.5 mm, hex shank

GEKO G38250 drill bit set contains 13 titanium-coated twist bits in sizes from 1.5 mm to 6.5 mm with hex shanks. The set is intended for drilling tasks in wood, plastics and soft metals. Titanium coating on the cutting edges improves wear resistance and increases heat tolerance during continuous drilling, while the hex shank design ensures secure engagement with hex-compatible chucks and quick-change holders. The compact assortment covers common small-diameter drilling needs and is suitable for both handheld drills and drill drivers that accept hex shanks.

Advantages

The titanium coating extends the service life of the bits and helps maintain cutting performance under higher temperatures. Hex shanks provide faster bit changes and reduce slippage in chucks and bit holders. A broad range of small diameters from 1.5 mm to 6.5 mm allows precise hole making for fastening, pilot holes and detail work. The set's compact format simplifies storage and transport.

Suitable for

• Drilling pilot holes in wood for screws and dowels
• Working with plastics and acrylic sheets
• Light drilling in soft metals such as aluminum and brass
• Small-diameter holes for electronics and model making
• Quick bit changes with hex-compatible chucks and holders

How to use

Select the appropriate bit size for the required hole diameter and secure it in a hex-compatible chuck or quick-change holder. When drilling, start at low to medium speed for precise positioning and increase speed as material and bit stability allow. Use a steady feed pressure and avoid excessive lateral force to prevent bit breakage. For metal drilling, apply cutting lubricant or coolant when appropriate to reduce heat buildup and extend bit life. After use, clean debris from the flutes and store the bits in their case to protect the titanium coating.

Usage recommendations

For best results, pre-drill clearance or pilot holes when driving screws in hardwood, and use a suitable lubricant for prolonged drilling in metals. Replace bits that show visible wear, loss of edge, or significant chipping to maintain hole quality and operator safety.
