Drill bit set Vorel 22190 — 19-piece Sthor 22190, assorted sizes

Vorel 22190 — 19-piece Sthor drill bit set provides a comprehensive selection of HSS drill bits for general metalworking and everyday drilling tasks. Supplied in a compact metal case, the set covers a continuous range of small to medium diameters to match a variety of drilling requirements. These bits are designed for use with standard handheld drills and drill drivers and are intended for DIY, home repair and light construction work where accurate, durable high-speed steel bits are needed.

Advantages

The drill bits are manufactured from high-speed steel (HSS) with a blackened surface finish and conform to DIN 338 geometry, delivering consistent cutting performance and wear resistance for metal and mixed-material applications. The assortment of 19 sizes reduces the need to change tools frequently and the metal storage case keeps bits organized and protected during transport and storage. The uniform shank and classic twist design ensure compatibility with common chucks and stable drilling operation.

Suitable for

• Drilling holes in metal sheets and thin-walled metal components
• General-purpose drilling in wood and some plastics when using appropriate speeds
• DIY home repairs and assembly tasks requiring multiple hole sizes
• Light construction and maintenance work with handheld drills

How to use

Select the drill bit matching the required hole diameter and insert it securely into the drill chuck, tightening according to the drill manufacturer’s instructions. Use appropriate cutting speed and feed for the material being drilled — lower speeds for harder metals and higher speeds for softer materials. Apply steady pressure without forcing the bit, and withdraw occasionally to clear chips and avoid overheating. When drilling metals, a cutting lubricant or coolant is recommended to extend bit life and improve hole quality.

Usage recommendations

For best results, clamp the workpiece firmly, start with a pilot hole for larger diameters, and use cutting oil when drilling steel or other hard metals. Replace worn or damaged bits to maintain hole accuracy and safety.
