## Long description

GRAPHITE 20 mm solid carbide drill bit (model 57H328) is designed for drilling clean, accurate 20 mm diameter holes in concrete and masonry. The bit features a solid carbide tip and a cylindrical straight shank compatible with hammer and rotary hammers that accept straight shanks. It is intended for tasks such as anchor installation, fixing systems, conduit and pipe entry, and general construction and renovation work where a robust, wear-resistant drilling tool is required.
Advantages
The solid carbide tip provides high hardness and extended cutting life when working in abrasive concrete and masonry. The straight cylindrical shank ensures compatibility with a wide range of rotary and percussion drilling tools that accept straight shanks. The 20 mm diameter delivers consistent hole size for anchors, dowels and fixings while the overall construction reduces breakage risk under typical construction loads.
Suitable for
Drilling 20 mm holes in concrete and masonry
Installing anchors, plugs and mechanical fixings
Preparing holes for conduit, pipes and cable entries
General construction, renovation and installation work
Key specifications
Diameter: 20 mm
Tip material: solid carbide
Shank type: cylindrical (straight) shank
Primary application: concrete and masonry
How to use
Select a drill or hammer drill that accepts straight cylindrical shanks and set the tool to the appropriate drilling mode (rotary or rotary-percussion) depending on material hardness. Mark the drilling location and start drilling at low speed to create a guide point, then increase speed and apply steady, moderate pressure. Clear dust periodically from the hole to improve drilling efficiency and reduce bit wear. For anchor installation, verify hole depth and cleanliness before inserting anchors or fixings.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling concrete. Match drilling speed and feed pressure to the material: excessive force or high speed may reduce bit life. For prolonged drilling in reinforced concrete or very hard aggregates, consider using intermittent drilling and clearing dust frequently to prevent overheating.
