Century Drill & Tool 83717 Sonic SDS Max Drill Bits With Multi-Cutter pneumatic accessory

SDS Max Bits for Reinforced Concrete

Century Drill & Tool 83717 Sonic SDS Max Drill Bits use a multi-cutter tip to prevent seizing in reinforced concrete. The reinforced crushing tips reduce vibration and protect the carbide from breakage. A self-centering point keeps the hole accurate from the start. Wear mark indicators show when a bit is no longer safe for anchoring work.

20× Speed Limit Over Standard Masonry Drills

The bits crush material up to 20 times faster than standard masonry drills. This speed applies to the SDS Max rotary-hammer interface they are built for. Performance drops if the tool cannot deliver the required impact energy or if the concrete aggregate exceeds the cutter design limits. Heat buildup in deep holes can also reduce the effective rate.

SDS Max Shank Fits Compatible Rotary Hammers

The SDS Max shank locks into any rotary hammer that accepts the SDS Max standard. No adapters or special tools are needed for installation. Problems usually arise when the chuck is worn or contaminated, which prevents the bit from seating fully. Using the bits in a standard SDS Plus chuck will not work and can damage both the bit and the tool.
