Why this disc stands out: the fiberglass-reinforced design delivers enhanced tensile strength and durability under high-speed use, reducing cracking and wear during quick, precise cuts. The slim 1/32" profile provides the finesse needed for fine trimming and accurate notches on metal, hard plastics, and composite materials, while the 1/8" arbor ensures broad compatibility with common rotary tools.
Ideal use cases
- Trimming thin metal stock or brackets in tight spaces where a larger wheel won’t fit
- Precision cutting and notching on plastic components and lightweight composites
- Deburring and cleanup after material removal to achieve smooth, accurate edges
- Miniature or hobbyist projects requiring controlled cuts with minimal material distortion
Practical tips for best results: run at or near the maximum speed specified (up to 45,000 RPM) with light, steady pressure—let the disc do the cutting rather than forcing it. Ensure your rotary tool is compatible with a 1/8" arbor and always use proper safety gear, including eye protection and a guarded setup. The 2-disc pack provides ready-to-use backups for ongoing projects or multiple workpieces.
Choose Gyros Tools Fiber Disk ST for dependable, high-tensile cutting performance that businesses and hobbyists can rely on. When precision, control, and durability are the priorities, these 1-1/2" cutting discs in a convenient two-pack are tailored to deliver.
