Pilot drill for SDS adapters 8x110 mm – Professional precision for demanding projects
Are you looking for a reliable and extremely precise tool for initial drilling into the hardest construction materials? The GEKO SDS 8x110 mm pilot drill bit (SKU: G40095) is a top-notch tool designed for flawless penetration into concrete, brick, stone and cement. This high-quality pilot drill bit is an indispensable piece of equipment for both professional builders and demanding DIYers who do not compromise on their work.
Thanks to its advanced design and proven SDS Plus clamping system, this drill bit ensures optimal power transfer from the rotary hammer directly to the workpiece. This means less effort, faster drilling speed and extremely precise results without unwanted slippage or material damage.

Why choose the GEKO SDS Plus 8x110 mm pilot drill?
When working with hard construction materials, it is crucial to use a tool that can withstand high loads and extreme temperatures generated by friction. The GEKO pilot drill is made of premium, heat-treated steel, which ensures exceptional wear resistance and a long service life, even with daily intensive use on the construction site.
Its primary function is to guide or center larger drill bits or adapters. Without a precise pilot drill bit, drilling larger holes in concrete is almost impossible, as the drill bits can quickly slip out of alignment. With a length of 110 mm and a diameter of 8 mm, this drill bit offers the ideal balance between stability and penetration depth.

Key features and technical specifications

Drill diameter: 8 mm – the perfect size for precise pre-drilling and stable guidance of adapters.
Total length: 110 mm – optimal length for a wide range of applications and achieving the appropriate depth.
SDS Plus clamping system: Allows for extremely fast tool changes without the use of an additional key and ensures a safe and firm connection to the impact drill.
Premium material: Made of high-quality steel that is resistant to bending, high temperatures and long-term stress.
Universal compatibility: Perfectly adapted for use with all standard SDS Plus rotary hammers, allowing maximum impact power.
Versatile use: Extremely effective when drilling in reinforced and classic concrete, silicate brick, natural stone, masonry and cement boards.


Advantages of using the GEKO pilot drill
Using a quality pilot drill brings numerous advantages that are directly reflected in the speed and quality of the work performed:

Exceptional precision without deviations: The drill bit prevents the drill bit from "dancing" across the surface when you start drilling. This ensures that the final hole will be exactly where you planned it.
Longer service life of the entire system: Since the pilot drill takes the first, heaviest impact and stabilizes the process, uneven wear on drill bits and adapters is reduced.
Time efficiency: Quick change with SDS Plus means less time wasted on the jobsite. Simply insert the drill bit into the chuck and you're ready to go.
Exceptional price-quality ratio: For an extremely affordable price, you get a professional tool that will cope with even the most demanding challenges in renovation or new construction.


A versatile partner for every construction job
Whether you're renovating a bathroom, installing electrical wiring, installing an air conditioner, or performing more demanding construction work, the GEKO 8x110 mm SDS Plus pilot drill is your ticket to professional results. Its robust design ensures that the drill bit won't break or bend even when it encounters harder obstacles in the material.
Rely on the proven quality of the GEKO brand and make your work easier with a tool that will never let you down.

Frequently Asked Questions (FAQ)
Which materials is this pilot drill best suited for?
The GEKO 8x110 mm SDS Plus pilot drill bit is specially designed for drilling into hard building materials. It achieves the best results when working with concrete, brick, natural and artificial stone, and cementitious materials.
Is this drill bit compatible with all drilling machines?
This drill bit uses the SDS Plus chuck. It is compatible with all rotary hammers and impact drills that have a standard SDS Plus chuck. It is not suitable for classic keyless chucks without the SDS system.
What is the role of the pilot drill when used with adapters?
The pilot (or centering) drill bit is placed in the center of the core bit adapter. Its function is to drill into the material first, thereby stabilizing and guiding the larger core bit. This prevents the core bit from moving and ensures a perfectly round and precise hole.

Same summary

The pilot drill bit for SDS adapters 8x110 mm is suitable primarily for users who occasionally drill holes in various materials and are looking for an easier solution for assembly or repair at home. The dimensions of the drill bit are suitable for frequent tasks where a smaller diameter and precise start of drilling with the appropriate adapter are required. This drill bit is a good choice for those who already have an SDS tool and need a pilot solution, but it is important for the user to consider the limitation - it is not intended for intensive professional tasks or drilling particularly hard materials such as concrete without the appropriate drill bit. Due to its multifunctional design, it is a good complement to the basic tool set for home use.
