Step Drilling Lubricant Guide – Cleaner Holes, Longer Bit LifStep Drilling Lubricant Guide – Cleaner Holes, Longer Bit Life
Drilling through hardened steel doesn’t need to be a fight. The right lubricant—like CUT-IT metal cutting paste—keeps your drill bit cool, clean, and cutting efficiently.
The Situation: Why Step Drilling Hardened Metal Is Tough
When drilling through thick or hardened metals, it’s common to use a step drill bit to gradually enlarge holes…
The Problem: Heat, Friction & Chip Welding
Each “step” of a step drill bit increases resistance. Without a proper lubricant:
- Heat builds up at the cutting edge
- Chips weld to the flutes
- Bit temper softens—reducing hardness and lifespan
The Implication: Time, Cost & Tool Waste
When bits overheat, you’re not just losing a tool—you’re losing efficiency…
The Need-Payoff: CUT-IT Paste Makes Step Drilling Easy
- Reduces friction & heat buildup instantly
- Stays in place—even when drilling overhead or vertically
- Cleans as it cuts, preventing chip welding
- Extends drill bit life up to 4X
