What problems it solves

This drill bit is purpose-built for metal drilling where control and durability matter. The 3-flat shank minimizes wobble in the chuck, reducing wandering on initial entry. The two-flute geometry clears chips quickly, lowering heat and chatter that can mar finished work. Its robust metal construction makes it a reliable choice for repeated use in demanding fabrication, automotive, HVAC, and DIY metal projects.

Ideal for

• Professional metal fabrication and workshop use
• Automotive and mechanical repair tasks
• DIY projects involving steel, aluminum, or other metals
• Through-holes and pilot-hole drilling where alignment and precision matter

Tips for best results

• Use a steady feed rate and apply cutting oil or coolant when drilling steel to reduce heat and extend bit life.
• Coordinate drill speed with material type—slower speeds for harder metals, faster speeds for softer metals.
• Keep the bit sharp and clean; a dull bit increases heat and can cause wandering.

With the Diablo Metal Demon 13/64 in. x 3.4 in. L drill bit, you gain a reliable tool that delivers precise holes and consistent performance across metalworking tasks. Add it to your toolkit for dependable metal drilling that professionals and serious DIYers can trust.
