Product Description
Milwaukee SDS+ Thin Wall Center Pin
Model Number: 48-20-6150
The Milwaukee 48-20-6150 is an SDS+ Thin Wall Center Pin — the centering pilot pin for use with Milwaukee SDS+ Thin Wall Diamond Core Bit adapter systems to provide accurate hole centering during the initial engagement phase of thin wall core drilling in concrete and masonry. The center pin inserts through the SDS+ adapter and thin wall core bit's center, extending beyond the diamond cutting segments to contact the work surface at the marked hole center and establish the correct drilling axis before the diamond rim begins cutting. Without the center pin, the thin wall core bit's large-diameter rim has no centering reference during initial contact with the flat concrete surface — allowing the bit to wander off the marked center before the diamond segments have established the circular kerf that guides subsequent drilling. The SDS+ thin wall center pin is specifically designed for the Milwaukee SDS+ thin wall adapter system's center pin engagement interface.
The center pin is a replaceable consumable item in the SDS+ thin wall core drilling system — it wears from repeated contact with concrete surfaces during the initial positioning phase of each hole's drilling cycle and requires periodic replacement to maintain the precise centering that accurate installation positioning requires. Using the correct Milwaukee center pin ensures the proper pin length and diameter for the SDS+ adapter's center pin bore and the core bit's center passage for correct centering function. Verify compatibility with your specific Milwaukee SDS+ thin wall adapter model before ordering.
