Carbide Multi-Material Drill Bits, 5 Pack

Milwaukee 48-20-8898 SHOCKWAVE™ Carbide Multi-Material Drill Bit Set – 5-Piece Impact-Rated Bit Set

The Milwaukee 48-20-8898 SHOCKWAVE™ 5-piece carbide drill bit set is designed for efficient drilling through a range of base materials using impact drivers, drill/drivers, or hammer drills with a 1/4" hex-compatible chuck. Engineered with multi-grind carbide cutting edges and impact-rated shanks, this set is suitable for masonry, metal, wood, tile, and composite substrates.

Each bit features an aggressive carbide tip geometry that enhances speed and extends bit life when used on stacked or dense materials. The hex shank design minimizes bit slippage and supports high torque transfer in both rotary and percussion modes.

Field Application Notes

This bit set is optimized for general construction, electrical, plumbing, and HVAC trades requiring consistent performance across dissimilar substrates. Carbide cutting edges are suitable for use with or without hammer mode, depending on the material. For harder aggregates or heavy-gauge steel, maintain moderate feed pressure and allow the bit to clear debris between cycles to prevent overheating.

Advantages for Trade Professionals

• Reduces Tool Change Time: Allows drilling into multiple material types with one bit set
• Increased Bit Life: Maintains edge sharpness over repeated metal and masonry use
• Impact Compatibility: Hex shank design supports high torque input without slipping or shearing
• All-Purpose Coverage: Covers the most common hole diameters used in mechanical fastening and fixture installation
