## Summary description

Step drill bit by GEKO, HSS substrate with TiAlN coating, cutting range 4–39 mm. Designed as a stepped (conical) bit for drilling progressively larger holes in metal, sheet, plastic and similar materials. Supplied as a pack of 50 identical bits; suitable for workshop use, production runs and repetitive drilling tasks requiring incremental hole sizes.

## Long description

Step drill bit GEKO step HSS TiAlN 4–39 mm is a stepped (conical) drill designed to create progressively larger holes in thin materials. Made on an HSS substrate and finished with a TiAlN (titanium aluminum nitride) coating, the bit covers a continuous cutting range from 4 mm up to 39 mm and is supplied as a pack of 50 identical pieces intended for workshop and production use where repeated incremental drilling is required.
Advantages
The TiAlN coating increases surface hardness and heat resistance compared with uncoated HSS, improving wear resistance during high-speed or continuous drilling. The stepped geometry allows multiple hole diameters to be produced with a single tool, reducing tool changes and setup time. Supplied in a bulk pack of 50, the set supports repetitive tasks and production environments by ensuring consistent tool availability and reduced downtime.
Suitable for
 Drilling progressively larger holes in thin metal sheets (steel, stainless steel, aluminum)
 Creating stepped holes in plastic and composite panels
 Workshop and production-line repetitive drilling tasks
 Deburring and enlarging existing holes to intermediate diameters
Key specifications
 Cutting range: 4–39 mm in stepped increments
 Material substrate: High-speed steel (HSS)
 Coating: TiAlN (titanium aluminum nitride) for improved heat and wear resistance
 Geometry: Stepped (conical) profile for multiple diameters per tool
 Pack quantity: 50 identical drill bits
How to use
Secure the workpiece and mark the initial drilling point. Install the step drill bit in a compatible drill or drill press chuck, ensuring proper centering and tight clamping. Start at low to moderate speed appropriate for the material—lower speeds for stainless steel and harder alloys, higher speeds for softer metals and plastics. Apply steady, moderate feed pressure and allow the bit to cut progressively through each step until the desired diameter is reached. Use cutting fluid or lubricant when drilling steel or stainless steel to extend tool life and reduce heat buildup. After use, inspect the cutting edges and clean off debris before storage.
Usage recommendations
For best results, select drill speeds and feed rates suited to the workpiece material, apply cutting fluid when machining ferrous metals, and replace bits from the pack when signs of wear or chipping appear to maintain hole quality and extend overall productivity.
