Combination bench stone for edge maintenance

This Norton 85455 bench stone combines coarse and fine silicon carbide grits on a single 8-inch plate. The dual-grade surface lets users establish a new bevel and then refine it without changing tools. It is built for workshop use on metals such as stainless steel, aluminium, brass, bronze, copper, titanium and masonry. Oil lubrication is recommended during sharpening.

Suited for general metalwork and tool upkeep

The stone serves machinists, maintenance technicians and hobbyists who need a versatile manual sharpener for the materials listed. It is not intended for high-volume production grinding or for automated sharpening systems. Users who require diamond or ceramic abrasives, water-based lubrication only, or a larger surface area should consider other options.

Dual-grade silicon carbide abrasive decides fit

The defining specification is the combination of coarse and fine silicon carbide layers bonded to one bench stone. This grit pairing determines whether the tool can both repair damaged edges and produce a finished cutting angle in a single workflow. Verify that silicon carbide and oil lubrication match the workpiece material and shop practice before purchasing.

Questions about this item

Should I choose the coarse or fine side of the 85455 bench stone?

The 85455 is a combination benchstone with both coarse and fine silicon carbide surfaces; use the coarse side for rapid material removal and the fine side for honing a keen edge.

How does the 8-inch length of the 85455 affect sharpening larger tools?

The 8-inch overall length provides a long stroke surface suitable for full-length passes on plane irons, chisels and kitchen knives without repositioning the blade.

What does the silicon carbide abrasive in the 85455 mean for lubrication choice?

Silicon carbide cuts aggressively on stainless steel, titanium and non-ferrous metals and is designed for use with oil lubrication rather than water.
