Best Hex Drill Bits in 2026

Most people assume that a standard high-speed steel bit is enough for a home workshop, but you'll quickly realize how much they struggle once you hit stainless steel or cast iron. These BAIDETS 1/8 inch bits change the game by utilizing M35 cobalt steel with a 5% cobalt content, which significantly boosts wear resistance. During testing, the 135° quick cut flow point was a standout, allowing for precise positioning and fast penetration without the bit walking across the surface. The fully ground spiral grooves do a great job of clearing out debris, which keeps friction and heat to a minimum. Whether you are tackling aluminum alloy or wood, this 10-piece set provides a reliable, durable solution for heavy-duty DIY tasks.

The metallic scent of shaved stainless steel fills the air as these bits bite into hard surfaces with surprising ease.

The 135° quick cut flow point is a game changer for precision, preventing that frustrating 'walking' effect when you first touch the metal. Because the spiral grooves are fully ground, they clear out debris quickly, which keeps heat levels down and prevents the bits from seizing up during deep holes. For a 13-piece set that includes everything from 1.5mm to 6.5mm, the included metal storage case makes it incredibly easy to keep your workbench organized for DIY repairs.

The sharp, aggressive bite of the 135° quick cut flow point makes short work of stubborn materials that usually stall standard bits.
