Drill bit Vorel Sthor 22611 — single-piece general-purpose metal/wood drill bit

Drill bit Vorel Sthor 22611 — single-piece general-purpose metal/wood drill bit is supplied as a single replacement or spare for handheld and bench drills. It is intended for everyday drilling tasks in workshops and at home, compatible with standard drill chucks when the drill’s chuck and the bit shank are matched. The bit is presented as a gradual/step-style cutting tool suitable for drilling a range of common materials including wood and various metals.

Advantages

The Vorel Sthor 22611 bit is made from high-speed HSS steel with a protective nitrogen-titanium surface treatment that improves wear resistance and heat behavior during drilling. Its gradual (step) geometry enables drilling multiple hole diameters with a single tool and reduces the tendency to wander on rounded or slippery surfaces. The cylindrical shank fits standard chucks and the grind and coating support faster heat dissipation and clean hole edges with minimal burrs when used within recommended material limits.

Suitable for

• Drilling holes in wood for general carpentry and repairs
• Drilling thin to medium sheet metals and colored metals
• Workshop and home maintenance tasks requiring a single spare or replacement bit
• Use with handheld or bench drills that accept cylindrical shanks

Key specifications

• Material: high-speed steel (HSS) with nitrogen-titanium coating
• Design: gradual/step drill geometry with multiple step diameters
• Shank type: cylindrical
• Typical applications: wood, steel sheets, stainless and structural steels, plastics and colored metals
• Features: automatic centering on rounded surfaces, reduced burr formation, improved heat dissipation

How to use

Install the Vorel Sthor 22611 drill bit securely in a compatible chuck, ensuring the cylindrical shank is properly seated and tightened. Select an appropriate drill speed for the material: lower speeds for stainless and hard steels, medium speeds for general steels and metals, and higher speeds for wood and plastics. Apply steady, even pressure; allow the bit to cut and clear chips periodically to avoid overheating. Use cutting fluid when drilling metals to prolong bit life and improve hole quality. After use, clean and store the bit to prevent corrosion.

Usage recommendations

Verify chuck and shank compatibility before operation, match drilling speed and lubrication to the material, and replace the bit if signs of wear or chipping appear to maintain safe and accurate drilling performance.
