ELIMINATE PILOT HOLES IN HARD MATERIALSWhen dealing with high-cost materials like porcelain tile, natural stone, or glass, bit walking is the primary cause of material damage and lost productivity. The Milwaukee 49-56-8025 Retractable Starter Bit is a mechanical solution engineered to integrate with Diamond Plus™ threaded hole saws, providing a precise centering point without the need for a dedicated pilot hole. The retractable carbide tip creates a secure anchor, allowing the diamond grit to engage the surface with surgical accuracy. This system maximizes the service life of your consumables and ensures a professional finish on the most abrasive materials, delivering a significantly lower cost-per-hole for the professional contractor. / Hardened Carbide Tip: Delivers aggressive marking on abrasive surfaces while maintaining edge retention through repeated cycles in stone and tile. / Retractable Mechanism: Automatically clears the path once the hole saw is engaged, allowing for continuous cutting without stopping to remove a pilot bit. / Universal Arbor Compatibility: Features a 1/4 in. size designed to fit standard hole saw arbors, ensuring versatility across your existing tool kit. / Optimized for Diamond Plus™: Specifically engineered to work with threaded hole saws ranging from 3/16 in. to 1-1/8 in. for maximum productivity.
