## Long description

Wapienica WIERTLO KWPN FI 20.00 300/400MM HM is a 20 mm diameter masonry drill bit with a hard-metal (carbide) cutting tip and available overall lengths of 300 mm and 400 mm. Intended for rotary drilling in construction and industrial environments, this drill bit is made to penetrate concrete, masonry, brick and similar materials where a durable carbide tip is required. It fits standard chuck-mounted rotary drills and compatible SDS systems when the shank type matches the drill.
Advantages
The carbide tip provides long wear resistance and maintains cutting performance when drilling abrasive materials. A 20 mm diameter offers a balance between hole size and chip removal efficiency for common installation and fixing tasks. The availability of two overall lengths (300 mm and 400 mm) allows selection based on required drilling depth and reach. The bit’s geometry is focused on reliable rotary drilling and stable penetration in dense substrates.
Suitable for
Drilling holes in concrete and reinforced concrete for anchors and dowels
Creating openings in masonry, brick and block walls
Installing electrical boxes, plumbing brackets and construction fixings
Industrial rotary drilling tasks where carbide tips are preferred
Key specifications
Cutting tip: carbide (hard metal) for increased durability
Diameter: 20 mm
Overall lengths available: 300 mm and 400 mm
Designed for rotary drilling in masonry, concrete and similar materials
Compatible with standard chucks and SDS-type systems when shank matches the drill
How to use
Select the bit length suitable for the required drilling depth and secure it in the drill chuck or compatible SDS-holder. Mark the drilling position, ensure stable drill alignment, and start at low speed to establish the hole, then increase speed and apply steady axial pressure appropriate to the drill and material. Periodically withdraw the bit to clear dust and debris to maintain cutting efficiency and avoid overheating. Use appropriate personal protective equipment and follow the drill manufacturer’s instructions.
Usage recommendations
For best results in dense concrete or reinforced sections, use a hammer-drill function where available and allow the carbide tip to do the cutting without excessive side load. For deeper holes choose the 400 mm length; for standard-depth anchor or fixture work select the 300 mm length. Inspect the carbide tip before use and replace the bit if the tip is chipped or excessively worn.
