Drill bit set Vorel 22330 — 19 pcs, assorted sizes, for metal and wood

Vorel 22330 is a 19-piece drill bit set designed for general-purpose drilling in metal and wood. The set contains a wide range of diameters to cover common drilling tasks and is suitable for use with hand drills and drill drivers in construction, repair and DIY projects.

Advantages

The drill bits are made of HSS (high-speed steel) and conform to DIN 338 parameters, providing consistent geometry and cutting performance. A titanium nitride (gold-colored) surface treatment increases surface hardness and wear resistance, extending tool life when used appropriately. The assortment of 19 sizes allows precise hole selection without changing to different sets, reducing downtime on multi-diameter jobs.

Suitable for

• Drilling holes in mild and stainless steels
• Drilling in wood and wood-based materials
• General construction and repair tasks
• Home DIY projects and hobby work

How to use

Select the drill bit diameter appropriate for the desired hole. Secure the workpiece and use suitable clamping to prevent movement. Install the chosen HSS drill bit in the chuck of a hand drill or drill driver and tighten the chuck securely. Start drilling at low speed to create a pilot entry, then increase speed as appropriate for the material. For metal drilling, use cutting fluid or lubricant to reduce heat and prolong bit life. For wood, apply steady pressure without excessive feed to avoid splintering. After use, clean chips from flutes and store bits dry to prevent corrosion.

Usage recommendations

Use drill speeds and feed rates appropriate to the material; reduce speed and apply cutting fluid when drilling stainless or acid-resistant steels. Wear suitable eye protection and follow safe drilling practices. Store the set in its case or a dry place to maintain the titanium nitride coating and overall condition of the bits.
