Drill Bit Set GEKO G40039 — 12-piece SDS Plus chisels and masonry bits

GEKO G40039 is a 12-piece drill bit set designed for SDS Plus rotary hammers. This kit includes a selection of masonry drill bits and chisel-type accessories intended for hammer drilling and light chiseling in concrete, brick and other masonry materials. The components fit SDS Plus tool holders and provide a compact solution for general construction, renovation and demolition tasks that require impact drilling and shaping.

Advantages

The set offers compatibility with SDS Plus rotary hammers, ensuring secure bit retention and efficient power transfer during hammering. A mix of masonry bits and chisels covers common drilling diameters and light demolition needs without requiring multiple separate purchases. The hardened steel construction of the accessories increases wear resistance under repeated hammer impact, while the organized kit format keeps tools accessible on-site or in a workshop.

How to use

Select the appropriate drill bit or chisel for the task and insert it fully into the SDS Plus tool holder until it locks. Use the rotary hammer in the recommended hammer-drill or chisel mode, applying steady pressure without forcing the tool. For drilling, start at low speed to establish a location, then use hammer action to penetrate masonry. For chiseling, set the tool to chisel mode and control the angle and blows to remove material safely. Replace worn bits when cutting performance or centering deteriorates.

Usage recommendations

Always wear appropriate personal protective equipment such as safety glasses, ear protection and dust mask when hammer drilling or chiseling masonry. Secure the workpiece and check that the rotary hammer is set to the correct mode before starting. Use lubricant or cooling only when recommended for a specific bit type and avoid excessive side loads to prolong tool life.
