Best Twist Drill Bits for Metalworking in Canada — Top 5 for 2026

Milwaukee's Shockwave Red Helix Cobalt set stands out in metalworking for its Red Helix flute geometry and cobalt-alloy construction that deliver aggressive chip evacuation, higher heat resistance and extended life under heavy use. Compared with the other sets here it commands a higher upfront price but reduces lifecycle cost per hole through longer tool life and impact-driver compatibility, making it best-in-class for tough, high-hour metal drilling jobs.

DEWALT's Pilot Point Industrial cobalt bits are a market-leading choice for precision metalworking because the Pilot Point tip gives reliable centering and reduced walking for repeatable, clean holes in production environments. They trade a bit of the rapid chip clearance found in helix-optimized bits for superior hole-start accuracy and consistent cycle times, which makes them financially attractive for shops that prioritize throughput and reduced rework versus the more aggressive Milwaukee design.

Norseman Viking HSS bits are a durable, value-oriented option for general metalworking—offering solid edge retention and toughness in standard high-speed steel without the premium of cobalt. Versus the cobalt and premium HSS options on this list they deliver a lower purchase price and sensible life for light-to-medium duty work, making them a cost-effective choice when heat and extreme hardness are not primary concerns.

Irwin's Turbomax Speed Helix series focuses on fast cutting and efficient chip evacuation through an optimized helix and flute geometry, enabling higher feed rates in metalworking while maintaining reasonable wear life. It sits between commodity HSS and full cobalt solutions in both performance and price—faster and more productive than basic HSS (like Norseman) but typically less costly than premium cobalt sets—so it’s a pragmatic option where speed and moderate durability are required.
