Milwaukee 49-56-7135 Retractable Starter Bit Large Arbor

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 49-56-7135 is a retractable starter bit and large arbor assembly designed for use with hole saws when cutting tile, stone, and glass. The hard carbide retractable bit marks the hole center securely before cutting begins, eliminating the need to drill a pilot hole first. This reduces setup time and improves centering accuracy on hard, brittle surfaces where wandering is common. The large arbor fits hole saws 1-1/4 inches and larger, removing the need for a separate arbor on compatible saw sizes. This tool is suited for tile setters, stone fabricators, and trade professionals who cut hard materials regularly.

This starter bit and arbor combination is intended for drilling into tile, stone, and glass using standard hole saws. It is well suited for residential and light commercial applications where accurate, centered cuts in hard surfaces are required. The retractable design allows the carbide tip to extend for marking and retract once the hole saw engages the material, keeping the bit protected during the cut. Installers working with plumbing rough-ins, electrical fixture cutouts, or HVAC penetrations through tile and stone surfaces will find this tool reduces rework from off-center starts.

Installation Notes

When cutting tile or glass, use appropriate coolant or water feed if required by the hole saw manufacturer to prevent cracking and extend bit life.
