Norton 3″ SG Blaze Speed-Lok TR Discs Grit 36 – 25 Pack

Description

Product Overview

The Norton 3″ SG Blaze Speed-Lok TR disc set is engineered for high‑performance sanding on the toughest metal substrates. Constructed from 100% ceramic alumina grain, each disc delivers a consistent 36‑grit finish that removes stock quickly while maintaining a cool cutting temperature. The proprietary self‑lubricating grain treatment reduces heat buildup, extending disc life and ensuring a smoother finish on stainless steel, alloy steel, and other hard metals. Dimensions measure 3 × 3 × 0.04 inches and each disc weighs 12.8 ounces, providing a lightweight yet durable solution for power sanders. The package includes 25 discs, each featuring the TR Type III roll‑on/roll‑off plastic attachment system, which enables rapid disc changes without the need for tools. This quick‑change capability minimizes downtime and maximizes productivity on the shop floor.

Usage

These discs are ideal for a range of industrial and fabrication applications where fast material removal and precise surface preparation are critical. Use them on a right‑angle grinder or a compatible power sander to deburr weld seams, blend welds, and strip paint or corrosion from metal surfaces. The coarse 36‑grit profile excels at removing excess material, shaping edges, and preparing surfaces for subsequent finishing operations such as polishing or coating. Because the discs are designed for a 3‑inch tool interface, they fit most standard handheld and bench‑mounted sanders used in automotive repair, aerospace maintenance, shipbuilding, and heavy equipment refurbishment. The self‑lubricating grain ensures that even under heavy load, the disc remains cool, reducing the risk of thermal distortion on delicate components.
