Spline Bit 2-Cutter 1-1/4 in. x 16 in. - Milwaukee Electric Tools

The Milwaukee 48-20-4125 Spline Bit is a professional-grade 2-cutter rotary hammer drill bit designed for demanding concrete and masonry applications. Engineered for maximum energy transmission, this bit ensures efficient material removal and consistent performance with spline drive hammer drills. It features a robust construction with superior quality carbide nibs, vacuum-brazed to a heat-treated steel body for enhanced durability and prolonged tool life.

Key Features

• Optimized Power Transfer: The spline shank design with 12 splines ensures positive engagement with the hammer drill's drive system, maximizing energy transmission from the tool to the bit for efficient pulverizing action.
• Durable 2-Cutter Head: Equipped with a 1-1/4 inch diameter, 2-cutter head, it efficiently breaks down concrete as the bit rotates and impacts the work surface.
• Premium Carbide Construction: Superior quality carbide nibs are vacuum-brazed to a heat-treated steel body, providing exceptional hardness and resistance to wear for extended use in tough materials.
• Efficient Material Removal: Designed to pulverize concrete effectively, contributing to faster drilling speeds and cleaner holes.
• Precision Drilling: Features a centering point and unique flute geometry for accurate, precise, and round holes with efficient dust removal.
