Olfa 45 mm Tungsten‑Steel Rotary Blade – 5‑Pack (RB45‑5)

Ideal for high‑precision cutting of delicate optical films, backlight foils, PET anti‑reflection coatings, and gaskets—without tearing, dusting, or smearing.

Why This Blade Is a Go‑To in Optical & Cleanroom Workflows

• Ultra-sharp tungsten-steel edge polished for clean, drag‑free cuts with exceptional edge retention. Cuts up to 8 layers of cotton fabric in one pass per OLFA manufacturing spec.
• Universal 45 mm diameter fits any standard rotary cutter—OLFA RTY‑2, RTY‑2/DX, RTY‑2/G, and equivalent models.
• Compact pack of five blades, each housed in a sealed plastic cartridge—perfect for batch cleanroom handling or rotation.
  

Target Applications

With razor-sharp control and minimal lateral pressure, these blades excel at:

• Backlight film trimming (PET stacks, vapor-deposited layers, TiGold HEA2000 AR film): ensures straight cuts without stretching, wrinkling, or leaving edge residue that can trap particles.
• Anti-reflection coating on PET substrates: maintains coating integrity and prevents micro-crack formation or surface delamination during edge trimming.
• Foam gasket strip cutting for touch‑panel seal and glass covers: produces crisp, square edges even for cushioned or pressure-sensitive foams, ideal for uniform gasketing and minimal flash.

Cleanroom & Optical Assembly Best Practices

1. Use a self-healing cutting mat, wiped between cuts with 70% IPA, to minimize adhesive residue transfer and extend blade life.
2. Handle workpieces gently, with materials held flat and in light tension—rotary action ensures low drag and less particulate generation than shears or knives.
3. Swap blades proactively: once edge performance begins to dull—e.g., slight fiber fuzz or resistance—use the next fresh blade.
4. Rotate the blade on quick-change handles to engage a fresh section of the rim for extended life.

Packaging & Specifications

The Olfa 45 mm Tungsten Steel 5‑Pack is the go-to precision blade for clean cutting in optical assembly environments—backlight film edge trimming, AR-coated PET sheets (such as TiGold HEA2000), adhesive-free foam gasket fabrication and exacting OCA prep work. With remarkable sharpness, compatibility across most cutters, and low contamination risk, it’s the most reliable tool for technicians working at the intersection of optical quality and cleanroom compliance.
