Power chainsaw sharpener Makita D-72154 — single unit, bench-mounted sharpening device

Makita D-72154 is a bench-mounted power chainsaw sharpener supplied as a single unit. Designed for restoring and maintaining cutting edges on chains, this workshop device provides consistent geometry and repeatable sharpening results to improve cutting performance and extend chain life. It is suitable for use in small repair shops, professional service bays and by home users who require accurate, mechanically guided grinding rather than manual filing.

Advantages

The Makita D-72154 offers stable bench mounting, a motor-driven grinding system and adjustable settings to achieve uniform tooth profiles. Its design reduces operator fatigue compared with hand filing and ensures repeatability across multiple teeth. The unit helps preserve chain dimensions and cutting angles so chains perform closer to factory specifications after sharpening.

Suitable for

• Repair shops and service workshops that sharpen multiple chains
• Forestry contractors and arborists maintaining their own equipment
• Homeowners and hobbyists who prefer bench sharpening over handheld methods
• Small-scale sawmill or carpentry operations that require consistent cutting performance

Key specifications

• Bench-mounted design for stable operation
• Motor-driven grinding for consistent tooth geometry
• Adjustable angle and depth settings for different chain profiles
• Single-unit supply for immediate installation on a workbench
• Suitable for restoring and maintaining cutting edges on common chainsaw chains

How to use

Secure the Makita D-72154 on a suitable workbench according to the mounting provisions, then fit the chain in the guide and set the grinding angle and depth to match the chain type being serviced. Start the motor and advance the grinding wheel to each tooth in turn, following the device's mechanical stops or adjustment marks to maintain uniformity. Clean the chain of filings and inspect tooth shape after sharpening; repeat passes if required until the desired profile is achieved.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves when operating the sharpener. Verify chain compatibility and follow chain manufacturer guidelines for correct filing angles and limits to avoid over-grinding. Periodically inspect and dress the grinding wheel for best performance and replace worn wheels as needed.
