Deprag W4 Compatible Milling Burs

Deprag W4 Compatible Dental Milling Burs

Aftermarket dental milling burs cut to match OEM geometry for the Deprag W4. These burs process zirconia, glass ceramic, PMMA and wax on the Deprag W4 under its native wet and dry spindle workflows workflow, with 3 mm typical Deprag handpiece shank so the tool changer accepts them without modification.

Bur selection on the Deprag W4

• Roughing pass: larger tip diameter for fast material removal on zirconia, glass ceramic, PMMA and wax
• Semi-finish pass: medium diameter for axial walls
• Finish pass: small diameter for detail and margin
• Shank: 3 mm typical Deprag handpiece shank for direct OEM replacement

Tool life notes

Keep a simple log (job count per bur, material, any margin issues) and the pattern becomes obvious within a week or two. Most early tool failures are feed/speed or coolant issues, not bur quality - sudden chipping usually means the collet is loose or the spindle TIR has drifted, not that the bur is defective.

Support

If the first bur you order does not drop straight into the Deprag W4 tool changer, contact us with a photo of the OEM bur alongside ours and we will confirm whether it is a shank-mismatch issue or something else. We would rather get the spec right before a second order than have you run a partial batch with the wrong tool.
