Koyo-Sha Bias Sisal Buff Disc

The Koyo-Sha Bias Sisal Buff Disc offers high-performance cutting and polishing performance with consistent results. Its bias-cut sisal construction and treated finish ensure excellent compound absorption, extended buff life, and reliable rapid polishing, helping fabricators improve workflow and finish quality on a variety of metals.

Features

Layered Sisal + Cotton Construction

The disc is made by die-cutting sisal and cotton sheets, layering them, then stitching in spiral from the centre to the edge. This prevents sisal fibres from fraying and improves compound retention.

Spiral Stitching

Spiral stitching ensures uniform tension, strength, and durability across the disc, essential for even and stable polishing.

Multiple Ply Options (4-ply, 6-ply)

Depending on the ply (number of sisal layers), the disc varies in thickness and hardness. More plies mean more material, hence greater cutting ability and durability.

Thin, Rigid Profile

Even though it is relatively thin (≈8 mm for 4-ply, ≈12 mm for 6-ply), the construction gives it sufficient stiffness. Good for small, narrow parts or detailed finishing where flexibility is not desired.

Good Compound Retention

The combination of sisal and cotton layers plus the spiral stitching helps the disc hold polishing compound more effectively for longer polishing operations.
