Shitime 21-Piece Diamond Chainsaw Sharpener Kit – 1/8 Shank, 5/32, 3/16, 7/32 Diameters

Fast, precise sharpening without removing the chain

Shitime’s 21-piece diamond chainsaw sharpening kit is designed to refresh chain teeth quickly, often in just a few minutes, without taking the chain off the bar. The streamlined workflow can be a convenient replacement for a hand chain saw file or sharpener, especially when you’re working from a cluttered workshop or on a job site.

What makes this kit stand out

The emery surface features evenly distributed particles for a fine, uniform filing effect. Users report clean cuts with big flakes rather than fine sawdust, which helps reduce dust while maintaining a sharp edge.

• Fast sharpening without chain removal for smoother, more efficient maintenance.
• Even emery distribution delivers a consistent filing action.
• Titanium-coated emery improves durability and longevity compared to non-coated options.

Durability and kit details

The set includes 21 pieces across three head diameters to cover common chain sizes: 5/32" (4.0 mm), 3/16" (4.8 mm), and 7/32" (5.5 mm). Each diameter has seven heads. The shank is 3 mm in diameter and the overall length is 1.77 inches, making the kit compact enough to carry in a toolbox or on site.

• Three grinding head sizes: 5/32", 3/16", 7/32" with seven pieces each.
• 3 mm shank and 1.77" overall length for portable use.
• Titanium-coated emery for solid, long-lasting performance.

Versatility and practical uses

Beyond chainsaw maintenance, the kit’s emery surface can be employed in mechanical and metalworking tasks and in woodworking, jade, and glass polishing. The material’s versatility makes it suitable for molds, steel bars, and other precision projects. It also serves as a practical gift for DIY enthusiasts, hobbyists, and professionals alike.

What to expect in real-world use

Results can vary by chain condition and material, but many users may experience a smoother sharpening routine, reduced downtime, and a sharper edge with less effort. Treat it as a potential upgrade to your maintenance toolkit rather than a guaranteed outcome.

Care and longevity

Because the emery is titanium-coated and designed for reuse, these heads can withstand regular use and light cleaning, offering longer life than basic grinding wheels when cared for properly.
