PEG Material — Polyethylene Glycol Block
PEG (polyethylene glycol) material blocks for diamond dressing and instrument conditioning. A simple, effective method for restoring cutting efficiency to clogged diamond burs, extending instrument life without chemical treatments.
Restore Diamond Bur Cutting Efficiency
Diamond burs lose cutting efficiency over time as the spaces between diamond particles become clogged with fine debris from the materials being cut — ceramic dust, metal particles, and acrylic residue. This clogging reduces effective cutting speed and increases heat generation, shortening instrument life. Wagner Precision PEG Material provides a clean, physical method of opening up clogged diamond surfaces: the soft, waxy polyethylene glycol matrix carries debris out of the diamond matrix during brief conditioning use, restoring the open cutting structure without chemicals.
- Cleans and opens clogged diamond bur surfaces mechanically
- Extends usable instrument life significantly
- Safe and easy to use — no chemicals or solvents required
- No chemical residue on instrument after dressing
- Compatible with all diamond bur types and grit sizes
- Can be used between cuts during long procedures to maintain efficiency

Why Diamond Burs Clog
Diamond burs cut via the exposed tips of diamond particles bonded to the instrument shank. Material debris from cutting — ceramic dust, metal fines, composite resin — accumulates between the particles and blocks the cutting action.
The soft PEG matrix enters the inter-particle spaces during dressing use, physically lifts the debris, and carries it away — restoring the open diamond cutting surface.
How to Use PEG for Diamond Dressing
Diamond dressing with PEG material is a quick, simple procedure that can be performed between cases or at any point during a procedure when cutting efficiency declines.
Mount the Diamond Bur
Seat the clogged diamond bur in the handpiece as normal. The dressing procedure is performed with the bur spinning at its standard working speed.
Run the Bur at Speed
Bring the handpiece up to normal operating speed. Run without water coolant for the dressing procedure — the dry contact with the PEG block is what performs the cleaning action.
Contact the PEG Block
Bring the spinning bur into light contact with the surface of the PEG block. Apply gentle pressure and make 3–5 short passes across the block surface for 5–10 seconds.
Return to Use
Blow any remaining PEG residue from the bur with an air syringe if needed. The bur is ready to return to use with restored cutting efficiency. Repeat as needed throughout the procedure.
