## Summary description

GRAPHITE SDS+ drill bit 4 mm (57H400) designed for drilling in concrete. Compatible with SDS+ hammer drills, it provides a 4 mm hole diameter for anchoring, doweling and installing fixtures.

## Long description

GRAPHITE SDS+ drill bit 4 mm (model 57H400) is a single-piece rotary-percussion bit designed for drilling small-diameter holes in concrete and masonry. Built for use with SDS+ hammer drills, this 4 mm concrete drill bit enables accurate anchoring, doweling and fixture installation where compact, precise holes are required. The bit is intended for both professional tradespeople and DIY users performing tasks that demand stable, repeatable results in hard materials.
Advantages
The SDS+ 4 mm drill bit offers reliable penetration in concrete thanks to its hardened carbide tip and spiral flute geometry that evacuates dust effectively. Its single-piece construction minimizes the risk of component separation under percussion loads, while compatibility with SDS+ chucks ensures secure bit retention and consistent transfer of impact energy. The compact 4 mm diameter allows precise positioning for anchors and small fasteners, reducing the need for rework.
Suitable for
 Drilling 4 mm holes for chemical and mechanical anchors in concrete
 Installing dowels, small bolts and screws into masonry
 Preparing pilot holes for light fixtures and switches on solid walls
 Repair and renovation tasks requiring precise small-diameter holes
Key specifications
 Shank type: SDS+ compatible shank for hammer drills
 Cutting diameter: 4 mm suitable for small anchors and fasteners
 Design: single-piece rotary-percussion drill bit for concrete and masonry
 Tip material: carbide cutting tip for increased wear resistance
 Flute: spiral flute for efficient dust removal during drilling
How to use
Fit the drill bit into the SDS+ chuck of a compatible hammer drill until it locks. Select an appropriate percussion or hammer-drilling mode for concrete and set drill speed according to manufacturer recommendations for a 4 mm hole—typically moderate speed with steady pressure. Begin drilling with a light, steady feed to establish the hole, then maintain consistent pressure and allow the tool's percussion action to advance the bit. Periodically withdraw the bit to clear dust if drilling deep holes. After completing the hole, clean out debris before inserting anchors or fasteners.
Usage recommendations
Use personal protective equipment including eye protection, hearing protection and dust mask when drilling concrete. For extended life of the drill bit, avoid excessive lateral force and keep the drill speed appropriate for masonry. Replace the bit when the carbide tip shows significant wear or when drilling performance decreases.
