CNC PRECISION MACHINED AVIATION ALUMINUM BODY — PROFESSIONAL FIBER CLEAVER FOR DAILY SPLICING: The TM20 body is machined from aviation-grade aluminum using CNC precision manufacturing — ensuring consistent blade contact geometry, stable cleave angle, and zero flex under repeated one-hand operation. The high-quality slider rail runs smooth with zero side-play, delivering flat end-face preparation on every cleave. Achieves ≤0.5° cleave angle with bare fiber diameter 125μm across single-mode G.652 and multimode fiber types. Designed and validated for professional daily use in FTTH, FTTB, and fiber-to-the-desk deployments. 24-POSITION BLADE WITH 48,000 CLEAVE LIFE AND AUTO-RETURN MECHANISM: The TM20 tungsten steel blade has 24 indexed cleaving positions — 50% more than standard 16-position cleavers — extending blade life to 48,000 total cleaves before replacement. The automatic rebound slider rail returns to the open position after each cleave without manual reset, increasing work throughput during high-volume FTTH installation sessions. Blade position indexes automatically; no manual height adjustment tool required. INTEGRATED 3-IN-1 FIBER FIXTURE — BARE FIBER, PIGTAIL & DROP CABLE IN ONE CLEAVER: The TM20's 3-in-1 fiber fixture handles 0.25mm bare fiber, 0.9mm tight-buffered pigtail, and 3.0mm jacketed leather cable without adapter changes. Cutting length range: 7–16mm providing flexibility for different splice protection sleeve requirements. The built-in fiber scrap collector captures cut waste inside the cleaver housing. Anti-broken fiber design prevents fiber crushing even in cold-weather field conditions below 0°C. COMPLETE FIBER OPTIC CUTTER FOR FTTH INSTALLATION, FIBER SPLICING & NETWORK MAINTENANCE: The TM20 handles the full FTTH workflow — drop cable termination, loose-tube cable splicing, pigtail preparation, and patch cord end-face preparation. Compatible with all major fusion splicers. Compact at 328g — lighter than most 24-position alternatives — fits alongside a fusion splicer in any standard FTTH tool bag. The compact design enables precise one-hand cleave initiation even in confined spaces. QIIRUN TM20 — PROFESSIONAL FIBER CLEAVER WITH DIRECT MANUFACTURER SUPPORT: The TM20 is purpose-built for fiber splicers and FTTH installation teams who need reliable daily-use performance. CNC aviation aluminum body, 24-position blade, auto-return mechanism, and ≤0.5° cleave angle — matched to field requirements, not lab specifications.

The QIIRUN TM20 is a CNC precision-machined optical fiber cleaver for FTTH installation teams, fiber splicers, and telecom technicians who demand professional cleave quality at a field-practical price. Aviation-grade aluminum body, 24-position tungsten steel blade, and auto-return slider mechanism — engineered for high-volume daily use.   TECHNICAL SPECIFICATIONS Cleave Angle: ≤0.5°typical Bare Fiber Diameter:125μm Supported Coating: 0.25mm/ 0.9mm / 3.0mm Cutting Length: 7–16mm Blade: 24-position tungsten steel | 48,000 cleave life | Auto-rotation Body: CNC precision machined aviation aluminum Rail: High-quality stainless steel (auto-return mechanism) Weight: 328g    Q: What is the difference between the TM20 and TM27? A: The TM20 uses aviation-grade aluminum with CNC precision machining to tighter tolerances than the TM27, adds 24 cleaving positions (vs TM27's 16), includes an auto-return slider rail for faster multi-cleave workflows, and supports a 7–16mm cutting length range (vs TM27's 9–16mm). Both achieve ≤0.5° cleave angle. The TM20 is the better choice for high-volume daily splicing work; the TM27 is ideal for occasional use or teams on tighter tool budgets. Q: What does the auto-return slider rail do? A: After each cleave, theTM20 slider rail automatically returns to the open (load) position without any manual reset action. During back-to-back splicing sessions, this saves approximately 5–10 seconds per cleave cycle and reduces operator fatigue over a full day of fiber work. Q: How does it perform in cold-weather field conditions? A: The TM20 includes an anti-broken fiber design that maintains consistent cleave quality even in cold environments below 0°C. This prevents the fiber-crushing failures that lower-quality cleavers experience when the blade contacts cold, brittle fiber.
