This refers to a specific type of shank and size combination for rotary hammer drill bits. SDS Max is a shank system designed for heavier-duty rotary hammers, providing a secure and efficient connection for transmitting high torque and impact energy. The “1/4 bit” component specifies the diameter of the cutting head, indicating a relatively small drill bit appropriate for tasks requiring precision or smaller holes.
The significance of this particular configuration lies in its ability to bridge the gap between power and finesse. SDS Max shanks are typically associated with larger diameter bits used for demolition or heavy concrete work. However, a smaller diameter provides increased control and accuracy. This combination is beneficial in scenarios requiring the power of an SDS Max hammer with the precision typically associated with smaller drills. Historically, this allows for increased versatility, eliminating the need for separate tools for large and smaller drilling tasks.
