## Summary description

GEKO G38506 is a set of four conical HSS drill bits with TiN coating designed for drilling aluminium and similar non-ferrous materials. The kit includes diameters Ø4–12, Ø4–20, Ø4–32 and Ø4–39, providing stepped hole sizes with a single tool. High-speed steel construction and titanium nitride finish improve wear resistance and cutting performance. Suitable for metalworking, fabrication and repair tasks.

## Long description

GEKO G38506 is a set of four conical HSS TiN-coated drill bits engineered for drilling aluminium and other non-ferrous metals. Each stepped bit provides a range of hole diameters in a single tool — Ø4–12, Ø4–20, Ø4–32 and Ø4–39 — allowing you to create progressively larger holes without changing tools. The combination of high-speed steel (HSS) construction and titanium nitride (TiN) coating increases surface hardness and wear resistance, while the conical (step) geometry supports controlled material removal and faster hole enlargement in thin and medium-thickness workpieces.
Advantages
The TiN coating reduces friction and extends cutting edge life compared with uncoated HSS, and the HSS core maintains toughness to resist chipping during drilling. Using conical step bits from this set simplifies operations where multiple hole sizes are required, reduces tool changes and improves workflow efficiency. The stepped design also helps deburring and creates consistent hole diameters while reducing the risk of snagging on softer materials like aluminium.
Suitable for
 Drilling aluminium sheets, plates and profiles
 Creating or enlarging holes in non-ferrous metals (brass, copper)
 Metalworking, fabrication and light repair tasks
 Situations where multiple hole sizes are needed without frequent bit changes
Key specifications
 Material: High-speed steel (HSS) with titanium nitride (TiN) coating
 Type: Conical (stepped) drill bits
 Set composition: 4 stepped bits covering diameters Ø4–12, Ø4–20, Ø4–32, Ø4–39
 Intended materials: Aluminium and other non-ferrous metals
 Typical applications: Progressive hole sizing and hole enlargement
How to use
Select the stepped bit that includes the target diameter and clamp the workpiece securely. Fit the bit in a drill or drill press chuck, ensure concentric mounting and set an appropriate rotational speed for aluminium—moderate to high RPMs depending on bit diameter and machine capacity. Use light feed pressure and steady cooling or lubrication if required to reduce heat buildup; withdraw the bit occasionally to clear chips. Start with the smaller steps and progress to larger diameters as needed for a clean stepped hole.
Usage recommendations
 For best results when drilling aluminium, use a suitable cutting fluid or light lubricant, maintain steady speed and feed, and avoid excessive pressure that can cause burring or bit overheating. Regularly inspect the TiN coating and cutting edges for wear and replace bits when performance declines.
