Classic diamond disc format trusted in dental laboratories and operatories for decades. Precision diamond coating on a traditional substrate, available in multiple diameters and four grit levels for ceramic, composite, and acrylic separation and contouring.
Traditional diamond discs remain the instrument of choice for many dental laboratories
and clinicians who rely on a familiar, proven format for separation and contouring
procedures. Wagner Precision’s traditional disc line carries the same commitment to
abrasive quality and dimensional consistency found across the entire Wagner instrument
portfolio.
Precision electro-deposited diamond coating is applied to a carefully selected steel
substrate, delivering aggressive initial cutting that is maintained consistently as
the disc wears. Available in three standard diameters and four grit levels to match
any separation or contouring workflow.

Each grit level is identified by a distinct color band on the disc substrate for
instant selection in a busy laboratory or clinical environment.
| Grit | Band Color | Particle Size | Primary Application |
|---|---|---|---|
| Coarse | Red | 125 – 150 µm | Aggressive separation; maximum material removal on hard ceramics and zirconia |
| Medium | Blue | 88 – 125 µm | General-purpose IPR and crown separation; most restorative materials |
| Fine | Yellow | 40 – 88 µm | Refined contouring, contact point adjustment, and pre-polishing passes |
| Extra Fine | White | 8 – 40 µm | Final surface smoothing after separation; composite and acrylic finishing |
Match disc diameter to the procedure. Use the 7/8″ for general contouring and
broad separation. The 3/4″ and 9/16″ sizes provide improved access in posterior
and anterior regions respectively.
Always operate with water coolant at the recommended speed range. Heat generated
during dry use at high RPM will degrade diamond bonding, shorten disc life, and
risk thermal damage to the restoration and adjacent structures.
Allow the diamond cutting surface to engage the material naturally. Excessive force
increases disc deflection risk, accelerates wear, and reduces cut accuracy. Short
intermittent passes yield superior results.
Examine each disc for substrate warping, cracks, or diamond delamination before
mounting. Discard any damaged disc immediately. Use only with a properly fitted guard.
Traditional diamond discs mount on standard screw-type and snap-on mandrels in
HP shank configuration. The precision-machined central aperture ensures a secure,
concentric mount at all operating speeds.
Wagner Precision mandrels are available separately and are compatible with all standard
high-speed laboratory handpieces. Mandrel and disc replacement programs are available —
contact us for volume pricing on mandrel/disc combinations.
Diamond discs must always be operated with a properly fitted safety guard. Never use
a diamond disc without a guard regardless of the speed or procedure type. Always inspect
the disc and mandrel for damage before each use. Discard discs showing any sign of
substrate cracking, warping, or diamond delamination.
