Oregon Tool H78 Controlcut 20 in Chainsaw Chain

Product Description

The OREGON TOOL H78 is a ControlCut replacement chainsaw chain designed for 20-inch guide bars. It uses Micro Chisel cutters with small-radius working corners that deliver consistent cutting performance while remaining easy to file and maintain in the field. Hardened rivets create a load-bearing surface that resists wear and reduces chain stretch, which means fewer tension adjustments during a work session. The low-kickback design helps meet safety expectations for both occasional property owners and working commercial cutters. At 0.812 pounds, the chain is lightweight and straightforward to handle during installation.

The H78 is suited for residential property maintenance, lot clearing, firewood cutting, and light-to-moderate commercial cutting applications. Its Micro Chisel cutter geometry performs reliably across a range of wood species and conditions. The low-vibration characteristic reduces operator fatigue during extended cutting. This chain is appropriate for gas-powered and compatible electric chainsaws fitted with a 20-inch bar.

Key Features

• Micro Chisel cutters with small-radius corners for smooth cutting and simple sharpening
• Hardened rivets resist wear and strengthen the chain under load
• Reduced chain stretch minimizes the frequency of tension adjustments
• Low-vibration design decreases operator fatigue during prolonged use
• Low-kickback construction for improved handling safety

Compatibility

Designed as an OEM-style replacement chainsaw chain for 20-inch guide bars on compatible gas-powered and electric chainsaws.

Installation Notes

Chainsaw chain installation and tensioning should be performed by a qualified operator following the saw manufacturer's guidelines. Always power down and engage the chain brake before handling the chain, and wear cut-resistant gloves throughout the process. After installation, verify correct tension by pulling the chain along the bar and confirming it seats firmly without sagging. Run the chain through a brief break-in cycle and re-check tension before returning to full cutting duty.
