Drill bit Vorel Sthor 22610 — single piece, standard size (1 pc)

Vorel Sthor 22610 — single-piece standard drill bit supplied as one unit for general-purpose drilling tasks. Made from high-speed HSS steel with surface nitride and titanium treatment, this graduated drill bit is designed to work across a range of materials including stainless steel, structural steel, non-ferrous metals, sheet metal and plastics. The bit features a cylindrical shank that fits standard chucks and a stepped (graduated) geometry that allows progressive hole sizing at 2 mm increments, providing precise control over hole diameter during workshop and construction use.

Advantages

The Vorel Sthor 22610 combines high-speed steel core strength with surface treatments that improve wear resistance and heat dispersion during prolonged drilling. Its stepped profile produces clean, well-defined hole edges and reduces the risk of grabbing on rounded or slippery surfaces. The cylindrical shank ensures compatibility with a wide range of standard chucks, making the single-piece supply convenient for replacing a worn bit or keeping a spare for on-site tasks.

Suitable for

• Drilling holes in stainless and structural steel
• Piercing sheet metal and non-ferrous metals
• Creating progressive-diameter holes in workshop fabrication
• Drilling plastics and thin construction materials
• Use with handheld drills and drill presses that accept cylindrical shanks

Key specifications

• Material: high-speed steel (HSS) with nitride and titanium surface treatment
• Type: stepped/graduated drill bit with increments every 2 mm
• Shank: cylindrical, compatible with standard chucks
• Application range: stainless steel, carbon/structural steel, non-ferrous metals, sheet metal, plastics
• Packaging: single piece (1 pc)

How to use

Secure the Vorel Sthor 22610 in a suitable chuck ensuring the cylindrical shank is clamped evenly and tightly. Select drilling speed appropriate for the material: lower speeds for stainless and hardened steels, moderate speeds for non-ferrous metals and higher speeds for plastics. Use cutting fluid or coolant when drilling hard metals to reduce heat and extend tool life. Advance the bit steadily, using the stepped geometry to achieve the desired hole diameter; retract occasionally to clear chips and maintain cooling.

Usage recommendations

For best results, start with a pilot position or center punch on sheet materials to prevent wandering. When drilling stainless or thick steel, apply a suitable cutting lubricant and use controlled feed to avoid overheating. Inspect the bit regularly for wear and replace the single-piece unit when tip rounding or dulling reduces cutting performance.
