![]() ![]() The Milwaukee Shockwave Red Helix drill bits were designed with drilling toughness in mind. The best drill bits penetrated surfaces quickly, drilled aggressively, and stayed sharp throughout the testing process.įor everyday drilling, whether on the job or for DIY projects, a set of dependable all-purpose bits comes in handy. I noted accuracy of hole placement and any movement of the bit prior to surface penetration, drilling speed, chip or “drill dust” consistency, and cleanliness of the holes at the entry and exit points. Following best practices for each bit type, drill type, and material type, I drilled three holes with each bit in every selected test material. Test materials included wood, PVC, and aluminum for titanium-coated high-speed steel bits cast iron, stainless steel, and aluminum for cobalt alloy bits brick, cinder block, and poured concrete for masonry bits and ceramic, travertine, and glass tiles for carbide-tipped tile bits.Īfter noting the physical characteristics of each bit set, I selected four different drill bits from each set. I tested the picks in a workshop using a benchtop drill press with a keyed chuck and a cordless drill driver with a keyless chuck. After reviewing more than 50 drill bit sets, I selected our top picks based on functionality, size combinations, cost, and availability. Then I began searching the most reputable tool brands to find the best drill bit designs and materials available. To kick off this project, I spent 20 hours researching drills and drill bits for common household repairs, maintenance, and DIY projects and learning about best drilling practices.
