  • Fine grade delivers smooth surface preparation
  • Open coating coverage reduces heat buildup on workpiece

Industrial deburring wheel for metal finishing

The 3M 14629 convolute wheel uses silicon-carbide abrasive in a non-woven, open-coat structure rated Hard density 8 and Fine grade. Its 8-inch diameter and 1/2-inch face width fit 3-inch arbor spindles on stationary or handheld tools. The gray XL-WL series wheel is built for consistent deburring, blending and finishing on ferrous and non-ferrous metals.

Sustained load performance at rated speed

At the maximum 500 RPM the wheel maintains a steady cut without glazing because the open coating releases swarf and reduces heat buildup during extended passes. The hard-density construction resists compression so the abrasive contact area stays uniform across long production runs. Load-resistant properties keep the surface free-clogging when working softer alloys or gummy materials.

Practical limits of the 500 RPM spindle interface

The 500 RPM ceiling means the wheel must run on equipment that cannot exceed this spindle speed; faster grinders will overspeed the bond and risk disintegration. The 3-inch centre hole requires a matching arbor or flange set, so machines with different bore sizes cannot mount the wheel directly. The 1/2-inch face width limits the contact patch, making the wheel unsuitable for wide-surface stock removal in a single pass.

Questions about this item

How much noise and heat does the 3M 14629 generate when running continuously at 500 RPM?

The wheel operates at 500 RPM with a non-woven silicon carbide construction that runs cooler than bonded abrasives; noise level depends on the drive tool and workpiece contact.

What drive tool and arbor are required to mount the 3M 14629 convolute wheel?

The wheel has a 3 in centre hole and 1/2 in face width; it must be mounted on a compatible bench grinder or sander arbor rated for at least 500 RPM.

Will the 3M 14629 fit on the same shaft as my existing 8 in grinding wheels?

Yes, the 8 in overall diameter and 3 in centre hole match common bench-grinder spindles; verify your machine’s maximum speed meets or exceeds 500 RPM before use.
