Best Practices for Use
To get the longest life out of these bits, keep these tips in mind:
Use Cooling Fluid: When drilling thick metal, use a few drops of cutting oil or multipurpose oil. This reduces heat and prevents the tip from dulling prematurely.
Manage Your Speed: Generally, the harder the metal or the larger the drill bit, the slower the drill speed should be.
Secure the Workpiece: Metal can catch on a drill bit and spin the material; always ensure your metal piece is clamped down securely before you begin.
