Drill Bit Set kwb 39 pc(s)

Combination bit and drill bit set with 39 pieces, including 24 universal 25 mm bits in the most common profiles, metal, wood and stone drill bits, socket bits, a countersink and a quick-change bit holder. All bits have a C6.3 shaft and are supplied in an L-box for organised storage. The set is designed for use with standard power drills and cordless screwdrivers and supports typical right-hand rotation operation.

Advantages

The kit provides a wide selection of bit profiles and drill diameters in one compact case, reducing the need to change tools between tasks. CR-V bit material offers good wear resistance for general screwing, while HSS metal drills and carbide-tipped stone drills provide appropriate cutting properties for metal and masonry. Standard C6.3/E6.3 shafts ensure compatibility with common bit holders and quick-change chucks.

Suitable for

• Screwing and fastening with common screw heads (Phillips, Pozidriv, Torx, Hex)
• Drilling in metal, wood and masonry
• General repair, assembly and DIY projects

How to use

Select the appropriate bit or drill for the material and task, insert it into the tool chuck or quick-change holder, and secure it according to the tool manufacturer’s instructions. Use the metal HSS drills for steel and non‑ferrous metals, wood drills with 3‑point tips for clean holes in timber, and carbide‑tipped masonry drills for brick, concrete or stone. Operate the drill or screwdriver at the recommended speed for the selected bit and apply steady, even pressure.

Usage recommendations

For longer tool life, avoid excessive axial force and high speeds on small diameter drills; use suitable cutting fluid when drilling metal; start masonry holes at low speed and increase as appropriate. Always wear eye protection and follow safety instructions of your power tool.
