Stop drilling wrong-sized holes.
You know the frustration. Hole's too small. Next bit makes it too big.
So you wiggle. You force it. The edge tears. Project ruined.
The Ironedge 6-piece hybrid set gives you 50 hole sizes from one case. Three step bits handle enlarging. Three sawtooth bits handle routing and slotting. HSS steel with titanium coating so they stay sharp — not just for the first hole, but the tenth.
No more swapping bits. No more guessing. Pick your size, drill, done.

✓ 50 sizes from 6 bits
Three pagoda-style step bits cover 3mm to 32mm. Three sawtooth bits handle slots and routing. One case replaces a drawer full of drill bits.
✓ Titanium coating that holds its edge
HSS 4241 steel with titanium plating resists heat buildup. Cuts stay sharp through aluminum, steel, plastic, and wood — not just the first hole.
✓ No more wrong-size holes
Each step is laser-marked for easy reading. Drill to the exact millimeter you need, then stop. No measuring. No guessing.
✓ Fits standard drills and impacts
Tri-flat shank locks into any 3/8" chuck or drill press. No slipping. No walking. Secure grip on every rotation.

Frequently asked questions
Can these cut through stainless steel?
These bits are designed for mild steel, aluminum, plastic, and wood. For hardened stainless or thick plate, use cobalt bits with cutting oil.
What size shank do they have?
All bits feature a tri-flat shank that fits standard 3/8" drill chucks and most drill presses.
Are the size markings easy to read?
Yes. Each step is laser-engraved directly into the steel for permanent, readable markings.
Do I need cutting oil?
For metal, light cutting oil extends bit life. For wood and plastic, no lubricant needed.
How to use
- Step 1: Select the bit that covers your target hole size.
- Step 2: Secure your workpiece. For thin sheet metal, clamp firmly to prevent spinning.
- Step 3: Start at low speed. Let the bit cut — don't force it. Use cutting oil on metal.
- Step 4: Stop when you reach the marked size you need. Clean edges, project done.
