Rotary Hammer Drill Bit GEKO G40025 SDS‑Plus 14 x 250 mm, pack of 100

GEKO G40025 is a pack of 100 SDS‑Plus rotary hammer drill bits with a 14 mm diameter and 250 mm overall length designed for impact drilling and light chiselling in concrete, masonry and natural stone. The bits are made for use with SDS‑Plus rotary hammers and are intended for repetitive, high‑volume drilling where consistent hole diameter and tool durability are required on construction and renovation sites.

Advantages

The set offers a uniform 14 mm diameter across all pieces, which simplifies tool selection and reduces downtime when multiple identical holes are needed. SDS‑Plus shanks ensure quick, secure fitting and efficient energy transfer from the hammer. The 250 mm length provides reach for medium‑depth anchoring and through‑material drilling while maintaining rigidity to resist bending. Supplied as a bulk pack of 100, the bits are convenient for professional applications and projects with continuous drilling requirements.

Suitable for

• Drilling anchor and fixing holes in concrete and aerated concrete
• High‑volume drilling tasks on construction sites and renovation projects
• Preparing holes for plugs and screws in masonry and stone
• Repeated impact drilling where consistent hole diameter is required

Key specifications

• Shank type: SDS‑Plus compatible
• Diameter: 14 mm
• Overall length: 250 mm
• Intended material: concrete, masonry, natural stone
• Pack quantity: 100 pieces

How to use

Insert the SDS‑Plus shank into the rotary hammer chuck until it locks. Select a hammer drill mode with impact enabled and use appropriate drill speed and feed pressure for the material—moderate steady pressure for concrete and harder stone, lighter pressure for softer masonry. Periodically withdraw the bit to clear debris and allow dust extraction if available. Use personal protective equipment such as safety glasses, hearing protection and dust mask during operation.

Usage recommendations

For optimal tool life, avoid excessive side load and overheating: allow the bit to cool between long drilling cycles and use an appropriate drill speed and impact setting for the material. When drilling deep holes, stage the operation by clearing debris frequently and consider using dust extraction or a vacuum to maintain visibility and bit performance.
