Drill bits Vorel 22340 set – 25 pieces

Vorel 22340 drill bit set – 25 pieces is a compact collection of high-speed steel twist drills designed for a range of general and repeat drilling tasks. The set contains multiple small- and medium-diameter bits that cover common hole sizes, packed in a practical metal case for organized storage and easy transport. These bits are suitable for work in wood, plastic and a variety of soft and harder materials where HSS performance and corrosion-resistant surface treatment are beneficial.

Advantages

The drills are manufactured from HSS high-speed steel and heat-treated to meet DIN 338 dimensional standards, providing consistent geometry and reliable cutting performance. A titanium nitride (gold-colored) surface coating increases surface hardness, reduces friction and extends tool life when drilling through tougher materials, including stainless and acid-resistant steels. The supplied metal case keeps the 25 bits neatly arranged and protects cutting edges during storage and transport.

Suitable for

• General repair and maintenance tasks around the house
• Woodworking and cabinetry when standard twist drills are required
• Drilling in plastics and composite materials
• Light metalworking, including drilling in stainless and acid-resistant steel
• DIY projects requiring a range of small to medium hole diameters

How to use

Select the drill bit diameter that matches the required hole size and secure it in the drill chuck, ensuring it is seated concentrically. Use appropriate drilling speeds and feed pressure for the material: slower speeds and steady pressure for harder metals, moderate speeds for plastics and higher speeds for softwoods. Apply cutting fluid or coolant when drilling stainless or acid-resistant steels to reduce heat buildup and preserve drill life. After use, clean swarf from the flutes and return bits to the metal case to protect edges.

Usage recommendations

Wear appropriate eye and hand protection when drilling. For best results on metal, clamp the workpiece securely and use center punches for precise starts on smooth surfaces. Replace dulled bits to avoid burning or oversized holes; maintaining correct speed and lubrication will prolong bit life and ensure repeatable results.
