1X Miller-Colburn Bone File 8.1 mm / 4.8 mm, Cross-Cut Paddle-End Bone Smoothing File

The 1X Miller-Colburn bone file is the base instrument in the Miller-Colburn cross-cut series and is selected whenever a case calls for flat, paddle-style bone smoothing rather than the curved or angled access offered by the 2X and 3X in the same series. Both working ends share the same paddle-shaped profile, so the instrument’s role is defined by width rather than a change in tip shape.

The larger paddle-shaped end measures 8.1 mm and is proportioned for broad ridge crest smoothing, while the opposite end is a smaller 4.8 mm paddle, exactly half the size of the larger end, for finer or more confined paddle-style work on the same handle. Because both ends carry a cross-cut serration, the file removes bone on both the push and pull stroke, which speeds smoothing across broader surfaces compared to a straight-cut instrument.

Clinically, the 1X is typically the first instrument reached for in the Miller-Colburn series before moving to the curved-end 2X or 3X, and it is well suited to general ridge and crest smoothing where the bone surface is relatively flat rather than contoured. Double-ended, medical-grade stainless steel, corrosion resistant, autoclavable.

Product Features

• 1X Miller-Colburn Bone File pairs an 8.1 mm and a 4.8 mm paddle-shaped end for two-direction cross-cut smoothing
• Smaller paddle end is proportioned to exactly half the size of the larger paddle end
• Cross-cut serration cuts on both push and pull strokes for efficient bone removal
• Flat paddle geometry on both ends suits broad to moderate ridge surfaces
• Entry instrument in the Miller-Colburn series, typically used before the curved-end 2X and 3X
• Consistent paddle-style access at two working widths on a single handle
• Medical-grade stainless steel, corrosion resistant, fully autoclavable

1X Miller-Colburn vs 2X Miller-Colburn: The 1X carries two paddle-shaped working ends, a larger 8.1 mm paddle and a smaller 4.8 mm paddle exactly half its size, for consistent paddle-style access at two widths. The 2X replaces one paddle with a curved working end for contoured surfaces. Start a series with the 1X for general paddle-end smoothing, then move to the 2X or 3X for curved or mixed-end access.
