Introducing the Fein Starlock 1-3/8 in. X 1-3/8 in. L Bi-Metal E-Cut Long-Life Saw Blade — a purpose-built oscillating-tool blade crafted to power through metal with precision and lasting durability. Built on bi-metal construction and tuned for the demanding routines of professional installers and serious DIYers, this blade is designed to deliver clean, fast cuts where it matters most.
Why this blade stands out
-
Bi-metal durability combines high-strength steel teeth with a flexible alloy backing. The result is a blade that resists tooth chipping and cracking under heavy use, extending life in challenging metals and profiles.
-
E-Cut Long-Life geometry optimizes tooth design for efficient metal cutting, delivering quick penetration and smoother edge quality without excessive heat buildup.
-
Compact, practical dimensions at 1-3/8 in length with a cutting depth of 1-5/8 in — ideal for tight spaces, furniture brackets, conduit runs, and other constrained-metal tasks.
-
Universal Starlock compatibility fits Starlock and Starlock Universal mounting systems, making it a versatile choice across a wide range of oscillating tools without the need for adapters.
-
Single-blade packaging in a clam shell keeps the blade protected and ready for immediate use on site.
Ideal use cases
This blade excels in metal-focused tasks where precision and durability matter. Use it for:
- Cutting metal studs, brackets, and channel in wall assemblies during renovations.
- Ripping through light-gauge steel and aluminum extrusions in fabrications or HVAC installations.
- Trimming conduit, metal housings, and fasteners in tight spaces where a traditional saw can’t reach.
- Shaping and deburring metal edging on DIY projects where a clean edge is essential.
How it improves your workflow
With the Fein Starlock E-Cut Long-Life blade, you’ll experience less blade downtime and more productive cuts. The bi-metal build reduces wear on the teeth, meaning fewer blade replacements during a project. The universal Starlock fit simplifies tool selection, so you can switch between compatible oscillating tools without swapping blades or adapters. This translates into faster job completion, less tool fatigue, and cleaner edge quality on metal work.
Practical tips for best results
- Allow the tool to do the work — steady feeds and light pressure minimize heat buildup and extend blade life.
- Keep cuts cool with brief pauses if you’re cutting through thick or tough metal profiles.
- Pre-score through stubborn spots with a light touch to reduce tooth strain and prevent wander.
- Inspect the blade after heavy use; replace if you notice chipped teeth or significant wear to maintain edge quality.
The Fein Starlock 1-3/8 in. X 1-3/8 in. L Bi-Metal E-Cut Long-Life Saw Blade is the reliable choice for those who demand longevity, compatibility, and precise metal-cutting performance from their oscillating tool.
