Master the Perfect Sharpening Angle with Hex-Tech
A portable manual hexagonal chainsaw file designed for precise chain tooth restoration. Keep your cutter teeth perfectly tuned with flat-edge cut technology and integrated physical angle guides.
Engineered for Precise Chain Maintenance
Hexagonal Sharpening Rod
The standard hexagonal cross-section profile matches your chain's cutting teeth perfectly. It refines cutter teeth into a sharp, straight angle, allowing you to slice wood fibers cleaner and significantly lower chain vibration.
Built-In Wing Angle Alignment
No more guessing. The handguard handle is uniquely engineered with dual wing guards pre-set to 25° on the left and 30° on the right. Keeping these wing guards parallel to your chainsaw guide bar makes perfect sharpening effortless for beginners.
Quick-Release Detachable Connection
The separable structure connects via a tight push-in hexagonal socket. Swap rod diameters as needed for different chains, save valuable storage space in your toolbox, and quickly swap files once worn out.
Hardened Hexagonal Teeth
Built from heat-treated quenched high-carbon steel, this sharpening rod delivers superb surface hardness. It cuts smoothly through tough chains while effectively resisting wear, deformation, and structural breakage.
Single & Double Cut Variations
Customize your file setup with two tooth-pattern options. Choose Single Cut for rapid, aggressive material removal, or select Double Cut for clean, fine-tooth polishing and smooth blade finishing.

Frequently Asked Questions
How do the left 25° and right 30° wing guides help when sharpening?
The handle's wing guards project flat outwards at pre-calculated angles (25° on one side, 30° on the other). During sharpening, keeping these wings visually parallel to your guide bar ensures your cutter profile retains the precise cutting angle without the need for guesswork.
Can I use the same handle to hold different file diameters?
Yes. The ergonomic handle is built with a standard quick-release hexagonal interface. You can insert any compatible hexagonal file rod size (3.8mm, 4.5mm, or 5.2mm) to adjust to different chain configurations quickly.
What is the difference between the Single Cut and Double Cut options?
The Single Cut file contains uniform parallel cuts, making it ideal for fast metal filing and quick rough grinding. The Double Cut file features cross-pattern teeth, designed for precision fine polishing and ultra-smooth tooth finishing.
